What Is This “App Tracking Transparency” Apple Added to iOS 14.5?

You’ve likely seen mention of the dispute between Apple and Facebook. It revolves around App Tracking Transparency (ATT), a technology Apple released in iOS 14.5.

The goal of ATT is to give iPhone and iPad users more control over the extent to which app makers can track their data and activities across apps and websites owned by other companies. Before App Tracking Transparency, nothing prevented companies from sucking a vast amount of data about your everyday activities and connecting it to other data to build an insanely detailed picture of who you are and what you do. Apple has written A Day in the Life of Your Data white paper and released the Tracked TV ad to give you a sense of how apps track you. We like to think of app tracking as a fleet of tiny drones constantly hovering over your head, recording your every waking moment for their corporate masters.

Facebook is particularly perturbed by the introduction of App Tracking Transparency because the company makes billions of dollars every year by gleaning as much as it can about you and then selling advertising access to you to companies that want to target people like you. For instance, Facebook knows if you’re a New York City lawyer and divorced mother of two who loves dogs, donates to the Sierra Club, and has Crohn’s disease. Although App Tracking Transparency won’t prevent Facebook from tracking your behavior across its own apps, at least it won’t be able to track you across other companies’ apps and websites.

Once you upgrade to the latest version of iOS and iPadOS, App Tracking Transparency requires that apps ask for permission to track you. However, depending on your current privacy settings, you may never see those requests. In Settings > Privacy > Tracking, if Allow Apps to Request to Track is turned off, you won’t receive any permission requests, and apps won’t be able to track you. Turn that setting on, and you’ll start getting alerts that ask for permission.

Put bluntly, there is absolutely no reason to allow any app to track you. Apple explicitly says that apps may not withhold features from those who opt out of tracking. So if you turn on the Allow Apps to Request to Track setting, tap Ask App Not to Track whenever you’re prompted. If you accidentally tap Allow, you can always go back to Settings > Privacy > Tracking and turn off the switch to rescind permission.

You might want to enable Allow Apps to Request to Track to see which apps were likely violating your privacy before and are still willing to do so even after App Tracking Transparency has exposed their sleazy business practices. Frankly, we’d encourage you to think about whether you want to use apps from such companies—perhaps the best reason to allow the requests is to identify privacy-abusing apps that you’ll then delete.

Early statistics from analytics company Flurry suggest that 94%–96% of users in the United States have opted out of app tracking, either by tapping Ask App Not to Track or by disabling the Allow Apps to Request to Track. We’re surprised the number is so low.

Social Media: New in iOS 14.5 is a privacy-protecting feature called App Tracking Transparency, which forces apps to ask you for permission to track your activities across other apps and websites. Learn more about why you should never allow tracking here:

It’s Time to Consider Upgrading to macOS 11 Big Sur

We’re cautious when it comes to recommending upgrades to new versions of macOS. Apple makes the upgrade process easy—though it can be time-consuming—but upgrading can create workflow interruptions, render favorite apps inoperable, and have other consequences. At the same time, it’s important to stay in sight of the cutting edge for security reasons and to take advantage of advances from Apple and other developers. Upgrading is not an if question; it’s a when question.

We’re not saying that everyone needs to upgrade to macOS 11 Big Sur now, but if you want to, it should be safe now that Apple has released several bug-fix updates. However, there are still a few caveats, and preparation is essential.

Reasons Not to Upgrade

Some people should continue to delay upgrades to Big Sur due to software incompatibilities. Most software under steady development will have been updated for Big Sur by now, but some workflows rely on older versions of apps where an upgrade isn’t practical or possible (ancient versions of Adobe Creative Suite, for instance), or on obsolete apps that will never be updated. You may be able to learn more at RoaringApps, but those who haven’t yet upgraded past 10.14 Mojave may have to upgrade or replace 32-bit apps that ceased working starting with 10.15 Catalina.

The other app category that continues to have trouble with Big Sur are backup apps that make bootable duplicates. Catalina moved macOS to its own read-only volume, and Big Sur goes a step further by applying cryptographic signatures that make it even harder for an attacker to compromise the operating system. Unfortunately, that also makes creating a bootable duplicate difficult. Carbon Copy Cloner and ChronoSync have developed workarounds; SuperDuper remains incompatible at this point, although an older version can create data-only backups. If you rely on one of these apps for critical backups, make sure you know what you’re getting into before upgrading or reassess your backup strategy.

Before You Upgrade

Once you’ve decided to upgrade to Big Sur, you have three main tasks:

  • Update apps: Make sure all your apps are as up-to-date as possible. If you regularly put off updates, now’s the time to let them complete so you have Big Sur-compatible versions.
  • Clear space: Big Sur needs a minimum of 35.5 GB to upgrade, and as of macOS 11.2.1, the installer won’t proceed unless there’s enough space. Don’t cut this close—you should always have at least 10–20% free space for virtual memory, cache files, and breathing room.
  • Make a backup: Never, ever install a major upgrade to macOS without ensuring that you have at least one current backup first. In an ideal world, you’d have an updated Time Machine backup, a bootable duplicate, and an Internet backup. That way, if something goes wrong as thousands of files are moved around on your drive, you can easily restore.

After those tasks are complete, make sure you don’t need your Mac for a few hours. There’s no telling exactly how long the upgrade will take, especially if it has to convert your drive to APFS, so never start an upgrade if you need the Mac soon.

Initiating the upgrade is just a matter of opening System Preferences > Software Update, clicking the Upgrade Now button, and following the instructions.

After You Upgrade

Part of the reason to set aside plenty of time for your Big Sur upgrade is that there are always clean-up tasks afterward. We can’t predict precisely what you’ll run into, but here are a few situations we’ve noticed:

  • macOS will probably need to update its authentication situation by asking for your Apple ID password, your Mac’s password, and if you have another Mac, its password too. Don’t worry that this is a security breach—it’s fine.
  • Some apps may have to ask for permission to access your contacts and calendar even though you previously granted permission. Again, that’s fine.
  • If you use your Apple Watch to unlock your Mac and apps (and you should, it’s great!), you’ll need to re-enable that in System Preferences > Security & Privacy > General.
  • If you use Gmail or Google Calendar or other Google services, you may need to log in to your Google account again.
  • Websites that usually remember your login state will likely require that you log in again. If you’re using a password manager like 1Password, that’s easy.
  • You may have to re-enable text-message forwarding to your Mac on your iPhone in Settings > Messages > Text Message Forwarding.
  • Those who use Backblaze for Internet backups will find their backups have been “safety frozen.” Follow these instructions for thawing your account.

Finally, Time Machine in Big Sur now supports and prefers APFS-formatted drives, and all of Apple’s development is going in that direction now. You can keep using your existing Time Machine backup in Big Sur, but after you’re confident that everything is working well—and you have another backup—it’s worth removing your Time Machine backup drive in System Preferences > Time Machine > Select Disk, reformatting the drive as APFS in Disk Utility, and restarting the backup in the Time Machine preference pane.

With all that housekeeping done, it’s time to check out all the new features in Big Sur!

Social Media: Should you upgrade to macOS 11 Big Sur? There’s no need to do so yet, but it should be safe for most people, so if you’re excited about the new look and the new features, this is a good time to upgrade. Read on for our pre- and post-upgrade tasks.

So, Are Apple’s New M1-Based Macs Any Good?

In November, Apple unveiled its new M1 chip and three new Macs that use it: the MacBook Air, 13-inch MacBook Pro, and Mac mini. The M1-based MacBook Air replaces the previous Intel-based MacBook Air, but with the 13-inch MacBook Pro and the Mac mini, Apple continues to sell some Intel-based models with beefier specs—most notably a higher memory ceiling.

Even though Apple makes impressive performance claims for the new Macs, the community was still somewhat skeptical. Were these new Macs as fast as Apple said? Would they be limited in some other way? And the biggest question of all, should we be buying untested M1-based Macs or tried-and-true Intel-based models? Now that these new Macs are shipping and people have had a chance to try them, let’s address these and other questions so you can plan your future Mac purchases appropriately.

Are these new Macs fast?

It’s hard to overstate just how astonishing the performance benchmarks for these new Macs are. In single-core GeekBench 5 tests, the M1-based Macs beat every existing Mac by a lot: the most recent 27-inch iMac clocked in at a benchmark score of 1250, whereas the M1 Macs hovered around 1700. (The Mac Pro and iMac Pro are tweaked for faster multi-core performance instead, so they fare even worse on the GeekBench 5 single-core benchmarks.) For many everyday apps, single-core performance is what you’ll notice.

Of course, the top-of-the-line 28-core Mac Pro and its siblings outperform the 8-core M1-based Macs in the GeekBench 5 multi-core benchmarks, but if you focus on the new M1 Macs in the multi-core rankings below, you can see that they’re just behind the fastest 27-inch iMacs and low-end Pro models. That’s doubly impressive when you remember that the Mac Pro in the screenshot below costs $6000, compared to $700 for the Mac mini.

Benchmarks don’t lie, but they also don’t tell the whole story. These new Macs feel fast. Apps launch with only a bounce or two of the icon on the Dock. The MacBook Air and MacBook Pro wake from sleep and unlock with an Apple Watch so quickly that they’re ready to use by the time you’ve finished opening the screen. We can’t promise you’ll never see the spinning beachball wait cursor, but we haven’t so far. In some ways, using these new Macs feels more like using a fast iPad or iPhone, where everything happens nearly instantly.

Finally, note that only apps that have been rewritten to support the M1 chip receive the full speed boost. Older apps must be “translated” by Apple’s Rosetta 2, which converts apps from Intel instructions to the Arm instructions needed by the M1. That happens at launch, after which macOS launches the translated app. The first launch might be slow, but subsequent launches are faster. Although emulation environments are generally quite slow, early tests show apps translated by Rosetta 2 as running at about 80% of native speed. The upshot of that is that even translated apps might run faster than the equivalent app running on an Intel-based Mac.

What’s the deal with the new M1-based Macs having only 8 GB or 16 GB of RAM?

With the new M1-based Macs, you can choose between 8 GB and 16 GB of RAM, and that’s it. In contrast, the current Intel-based 13-inch MacBook Pro lets you go up to 32 GB, and the Intel-based Mac mini can take up to 64 GB.

Although 16 GB of RAM sounds limiting, that doesn’t seem to be nearly as concerning as one might think. The reason is that the M1 chips use what Apple calls “unified memory,” which is built onto the M1 chip itself and shared by the CPU, GPU, and Neural Engine. A significant performance bottleneck in modern computers is moving data around in memory. Benchmarks suggest that the memory bandwidth on the M1 chip is about 3x faster than on a 16-inch MacBook Pro. The faster that data can be moved around in memory and shared between the processing cores, the less memory is needed.

The speed of their SSDs also lets the M1-based Macs get away with less memory. When macOS uses all its physical RAM, it falls back on virtual memory, which effectively involves moving data on and off the SSD as needed. When Macs used hard drives, swapping memory to and from disk was very slow, but modern SSDs are fast enough to hide swapping delays.

To be fair, there are still memory-intensive tasks that will run better on Macs with lots of physical RAM. That’s a big reason Apple kept the Intel versions of the 13-inch MacBook Pro and Mac mini for sale. On the very high end, you can put a whopping 1.5 TB of RAM in a Mac Pro, and if you need that kind of RAM for your work, you’ll need to stick with Intel-based Macs for now.

How will the M1-based Macs fit into a workflow?

Here’s where things get tricky. If you have an office full of Macs, there are some good reasons why you might want to stick with Intel-based Macs for a while.

  • Big Sur: The M1-based Macs require macOS 11 Big Sur. In general, we recommend that people hold off on upgrading to Big Sur until Apple has released maintenance updates to solidify stability and compatibility. Plus, mixing versions of operating systems and apps can lead to interoperability problems.
  • Apps: Although Rosetta 2 appears to do a good job translating older apps, there may still be quirks or performance hits, particularly for complex apps.
  • Memory: As mentioned above, there are some tasks where lots of physical RAM is essential, and there’s currently no way to go above 16 GB on an M1-based Mac.

But here’s the thing. Apple very intentionally focused its initial M1-based Mac models on the low end of the Mac product line. These Macs are ideal for students and individuals, or as auxiliary or traveling Macs for office workers, particularly given the startlingly good battery life in the laptops. They won’t be replacing a Mac Pro or even a 27-inch iMac right now, but no one would have replaced such a machine with a MacBook Air, 13-inch MacBook Pro, or Mac mini before either.

In the end, we’re bullish on these new M1-based Macs. They’ve redefined what the most inexpensive Macs can do, making them compelling for those who don’t require more than 16 GB of physical RAM or need to slot them into highly specific workflows.

Social Media: Apple’s new M1-based Macs are getting rave reviews for their stunning performance and battery life. Should you buy one for your next Mac or stick with a tried-and-true Intel-based Mac? We look into that question in this piece.

Don’t Succumb to iOS 13 Update Fatigue!

Does it seem like that red badge on the Settings app indicating that there’s a new iOS 13 or iPadOS 13 update pops up at least once per week? You’re not imagining things—Apple has been frantically squashing bugs in its mobile operating systems since their release in mid-September.

If you haven’t yet upgraded from iOS 12, there’s no harm in waiting until the new year to see if things have settled down. (Well, no harm as long as you don’t receive a pair of Apple’s snazzy new AirPods Pro as a holiday gift, since they work only with devices running at least iOS 13.2, iPadOS 13.2, watchOS 6.1, tvOS 13.2, and macOS Catalina 10.15.1.)

That said, given Apple’s generally reliable record with major iOS updates, many people have upgraded to iOS 13. You shouldn’t feel bad if you have done so, either. Despite Apple’s flurry of bug fix updates, the overall user experience with iOS 13 has been generally acceptable.

Even if you haven’t noticed problems with iOS 13, it is important that you keep installing all these smaller updates, because they fix problems that could be serious. More important yet, if you do have trouble with your iPhone or iPad, and you’re not running the latest version of iOS or iPadOS, updating is the first fix to try.

To hammer home why you should stay up-to-date with iOS releases, here’s a brief timeline of Apple’s fixes so far:

  • iOS 13.0 (September 19): This was the initial release of iOS 13 for the iPhone, with oodles of new features… and lots of bugs. Apple promised iOS 13.1 and the first release of iPadOS 13.1 for September 29th, with additional features and bug fixes.
  • iOS 13.1 (September 24): After iOS 13.0 received scathing reviews in early iPhone 11 reviews, Apple moved the release date of iOS 13.1 up by five days. It added more features and addressed numerous bugs with Mail, Messages, Reminders, Notes, Apple ID sign-in, the Lock screen, and more.
  • iOS 13.1.1 (September 27): This quick Friday release the same week as iOS 13.1 fixed bugs that could prevent an iPhone from restoring from backup, cause batteries to drain too quickly, reduce Siri recognition accuracy, bog down Reminders syncing, and allow third-party keyboard apps to access the Internet without your permission.
  • iOS 13.1.2 (September 30): The next Monday brought iOS 13.1.2, which ensured that the progress bar for iCloud backups would disappear after a successful backup, addressed bugs that caused the Camera app and flashlight to fail, and improved the reliability of Bluetooth connections in some vehicles.
  • iOS 13.1.3 (October 15): After a two-week breather, this update addressed bugs that could prevent incoming calls from ringing, block meeting invites from opening in Mail, cause incorrect data in Health after daylight saving time changes, prevent apps and voice memos recordings from downloading after restoring from iCloud Backup, stop an Apple Watch from pairing successfully, and cause Bluetooth connection problems with vehicles (again) and hearing aids.
  • iOS 13.2 (October 28): With this update, Apple delivered additional promised features, including support for the HomePod, Siri privacy options, HomeKit Secure Video, new emoji, Deep Fusion in the iPhone 11 Camera app, and AirPods Pro support. It also fixed a bug with password autofill in third-party apps, resolved an issue that prevented swipe to go home from working on the iPhone X and later, eliminated a problem that caused saved notes to disappear temporarily, and ensured that manual iCloud backups completed successfully.
  • iOS 13.2.1 (October 30): As it turned out, iOS 13.2 could brick HomePods during installation or after a reset. This HomePod-exclusive update fixed that bug.
  • iOS 13.2.2 (November 7): This update stomped a big bug that could cause apps to quit unexpectedly in the background, potentially causing data loss and draining the battery more quickly. It also addressed two bugs that could cause an iPhone to lose cellular service.
  • iOS 13.2.3 (November 18): This release resolved one bug that could cause searches in Mail, Files, and Notes to fail and another that prevented photos, links, and other attachments from displaying in the Messages detail view. It also addressed problems that could prevent apps from downloading content in the background and prevent Mail from fetching new messages and including and quoting original content when replying.

With luck, you never ran into any of these bugs—they weren’t universal. But the problems were real, and they inconvenienced plenty of people. Just like with vaccinations, staying current with your iOS updates is the best way to keep the bugs at bay.

Social Media: Apple has been squashing bugs in iOS 13 and iPadOS 13 left and right, with numerous updates since their September release. If you’ve upgraded already, we recommend that you keep installing maintenance fixes as they come out.

When Should You Upgrade to macOS 10.15 Catalina, iOS 13, iPadOS 13, watchOS 6, and tvOS 13?

As we get into September, it’s a good bet that Apple will be pushing out the next major versions of macOS, iOS, watchOS, and tvOS, along with the new iPadOS, which is iOS with iPad-specific tweaks. Apple previewed these new versions back in June, and they’ve been in public beta since. Once Apple makes macOS 10.15 Catalina, iOS 13, iPadOS 13, watchOS 6, and tvOS 13 available, the question looms large—when should you install them?

(Note that we say when and not if. There’s no harm in delaying major operating system upgrades until Apple has squashed early bugs. But waiting too long puts you at risk from security vulnerabilities and prevents you from taking advantage of compelling new features. Plus, should you have to replace one of your Apple devices unexpectedly, you will likely have to use the current operating system, which could be awkward if you weren’t prepared.)

macOS 10.15 Catalina

We’ll start with the hardest decision—when should you upgrade to macOS 10.15 Catalina? Two features might make you want to upgrade soon: Screen Time and Voice Control. With Catalina, Macs get the same usage monitoring and limit setting that Apple introduced in iOS 12, which will make Catalina a must-have for parents trying to help Mac-using kids focus on what’s important. Voice Control makes it vastly easier to control your Mac—and dictate!—with just your voice, so if that’s compelling, look into upgrading soon.

Other new features are also attractive, such as dedicated Music, TV, and Podcasts apps that replace iTunes; using an iPad as a second screen or graphics tablet; and improved versions of Reminders, Notes, and Photos. They won’t drive most immediate upgrades, though.

Catalina has one big gotcha—it won’t run old 32-bit apps. If you rely on apps you haven’t updated in the last few years, hold off on Catalina until you’ve figured out how to update or replace them.

Regardless, we recommend waiting until at least version 10.15.1 or even 10.15.2 before upgrading. That gives you time to make sure your key apps are fully compatible with Catalina and for Apple to resolve any unanticipated problems. When you’re ready, check out the ebook Take Control of Upgrading to Catalina if you want detailed advice on how to do it right.

iOS 13

While we urge caution with macOS updates, iOS updates are an easier decision. Apple boasts that iOS 13 improves performance, particularly with Face ID unlocking and app launches, which many people will appreciate. iOS 13 also now offers a Dark mode like macOS that may be easier on the eyes in dark rooms, though light-on-dark text is generally harder to read than traditional dark-on-light text.

Photos in iOS 13 significantly improves photo editing, with portrait lighting control, a high-key mono effect, and individual adjustment and filter controls. Nearly all these editing tools work with videos too! Apple completely rewrote Reminders, adding smart lists and integrations that let Siri suggest reminders, as well as a quick toolbar to add times, dates, locations, and more to your reminders. iOS 13 also enhances Maps with Look Around, a Google Maps Street View competitor that gives you a 360º view of supported areas. Maps also features a rebuilt map with more detail, favorites, and collections of places to see.

iOS 13 may not be life-changing unless you plan to rely on its addition of Voice Control instead of touch, but we think it’s a good upgrade. Give it a week or two to make sure there isn’t a major gotcha that Apple missed, but after that, install when you have some time to play with the new features.

iPadOS 13

iPadOS 13 is “new,” but it’s not an entirely new operating system to learn. Instead, it’s a superset of iOS 13 with iPad-specific features. The Home screen can hold more icons, and you can pin Today View widgets to the side for quick access. Safari in iPadOS is now a desktop-class browser that lets you use complex Web apps like Google Docs, Squarespace, and WordPress much as if you were on a Mac. Apple also extended the iPad’s multitasking features so you can switch between multiple apps in SlideOver, open multiple “windows” for a single app in Split View, and use App Exposé to navigate among app combinations.

If you already use your iPad for productivity, we think iPadOS 13 will be a no-brainer upgrade. As with iOS 13, though, it’s probably best to wait a week or so to install, or until you’re certain that your key apps have been updated to be compatible.

watchOS 6

Once you’ve updated your iPhone to iOS 13, there’s no reason not to update to watchOS 6. It’s not a huge update, but it has some nice features. Most interesting are the health-related improvements, a Cycle Tracking app for women and a Hearing Health app that warns you when the ambient noise in your environment has risen to dangerous levels. Apple has also introduced new watch faces that may float your boat, Siri can identify songs playing nearby and return Web search results to your wrist, a new Audiobooks app lets you listen anywhere, and Activity Trends help you track your workout progress over time.

tvOS 13

tvOS 13 is the easiest to agree to install, and it has some welcome new features. Apple redesigned the Home screen a bit and allows the apps in your top row to play video previews of their content (but you can shut those off if you don’t like them). More compelling is the addition of Control Center, which lets you put the Apple TV to sleep, control background audio playback, choose audio output, search, and switch between users.

That’s right, tvOS 13 introduces multi-user support that changes the content within apps based on the current user. (Speaking of multi-user support, iOS 13 on the HomePod also now differentiates based on who’s speaking—finally!) tvOS 13 can also display lyrics in the Music app and supports Xbox One and PlayStation 4 wireless gaming controllers for Apple’s upcoming Apple Arcade service. And it boasts a new collection of gorgeous underwater screen savers.

Change can be hard, but we’re excited about these new operating systems. Like you, we won’t use all the new features, but we’re confident that some of them will radically enhance the experience of being an Apple user.

Social Media: So many new operating systems—macOS 10.15 Catalina, iOS 13, iPadOS 13, watchOS 6, and tvOS 13! We have a brief overview of the new features and calm advice on when you should upgrade each of your Apple devices to the new hotness.

Some May Like It Hot… But Your Technology Prefers to Stay Cool

When summer brings sunny days and rising temperatures, you may have ditched your business suit for shorts or skirts to stay comfortable, but your technological gear can’t do the same. And keeping your tech cool is about more than comfort—as temperatures rise, performance can suffer, charging may get slower or stop, various components might be disabled, and devices can become unreliable.

How Hot Is Too Hot?

You might be surprised by the recommended operating temperatures for Apple gear—whether you’re talking about an iPhone X or a MacBook Pro, the company recommends staying under 95° F (35° C).

Such temperatures happen regularly throughout the summer. Even in cooler climes, the temperature in a parked car in the sunshine can easily hit 130º F (54º C) in an hour and rise higher as time passes. And no, cracking the windows a couple of inches won’t make a significant difference. We hope you’re already thinking about that with regard to children and pets, but as you can see, tech gear should also be protected. Apple says its products shouldn’t even be stored—turned off—at temperatures over 113º F (45º C).

It’s not just cars you have to think about. Temperatures in homes and offices without air conditioning can also rise higher than electronics would prefer, and that’s especially true for computers that stay on most of the time and aren’t located in well-ventilated areas.

What’s the Danger?

First off, remember that all electronic devices produce their own heat on top of the ambient heat in the environment, so the temperature inside a device can be much, much hotter than outside. The CPU in an iMac can hit 212º F (100º C) under heavy loads.

Temperatures higher than what components are designed for can have the following effects:

  • Chips of all types can behave unpredictably as increased thermal noise (electrons vibrating more) causes a higher bit error rate. Because electrical resistance increases with heat, timing errors can also occur.
  • Lithium-ion batteries discharge well in high temperatures, but the increased rate of chemical reactions within the battery will result in a shorter overall lifespan.
  • As devices heat and cool, the uneven thermal expansion of different materials can cause microscopic cracks that can lead to a variety of failures over time.

Some heat-related problems are temporary, so when the device or component cools down, it will resume working correctly. But others, particularly drops in battery life—are irreversible and particularly worth avoiding.

When a Mac gets too hot, it will spin up its fans in an attempt to keep its internal components cool. If your Mac’s fans are ever running at full tilt, first quit apps you aren’t using, particularly those that might be CPU-intensive and thus creating a lot of heat. If that doesn’t make a difference, restart it to make sure the problem isn’t some rogue process. If the fans come back on at full speed quickly, shut it down and let it cool off for a bit. In the worst case, an overheated Mac will start acting unpredictably or crash.

iOS devices don’t have fans, so they employ other coping mechanisms. If your iPhone or iPad gets too hot, the device will alert you.

Apple says you might notice some of the following behaviors:

  • Charging, including wireless charging, slows or stops.
  • The display dims or goes black.
  • Cellular radios enter a low-power state. The signal might weaken during this time.
  • The camera flash is temporarily disabled.
  • Performance slows with graphics-intensive apps or features.

If you’re using Maps on an overheating iPhone for GPS navigation in the car, it may show a “Temperature: iPhone needs to cool down.” screen instead of the map. You’ll still get audible turn-by-turn directions, and the screen will wake up to guide you through turns,

How to Keep Your Tech Cool

For the most part, keeping Apple devices cool just requires common sense, since you’d do the same things for yourself.

  • As Apple’s specifications recommend, avoid using devices when the temperature is over 95º F (35º C). If you can’t avoid it entirely, keep usage to a minimum.
  • Don’t leave devices in cars parked in the sun for long periods of time. If it happens accidentally, let the device cool before using it.
  • Provide good ventilation so air can cool the device. Don’t block ventilation ports in the back of desktop Macs, and don’t use Mac laptops in bed, propped on a pillow, or under the covers. It can be worth vacuuming dust out of ventilation ports every so often.
  • Never put anything on the keyboard of an open Mac laptop.
  • Avoid stacking things on top of a Mac mini.
  • Monitor the temperature of server closets. If they get too hot, keep the door open, add a fan, or run the air conditioning.

Luckily, the temperatures that cause problems for Apple hardware aren’t terribly comfortable for people either, so if you’re way too hot, that’s a good sign your gear is as well.

Social Media: How hot is too hot for your Apple devices? You may be surprised by the answer.

What’s with All These Dialogs Saying, “SomeApp is not optimized for your Mac”?

If you’re running macOS 10.13.4 High Sierra or macOS 10.14 Mojave, you may have seen a dialog that says an app isn’t optimized for your Mac. The message differs slightly between High Sierra and Mojave, with the High Sierra version telling you the developer needs to update the app to improve compatibility whereas Mojave saying bluntly that the app won’t work with future versions of macOS.

What’s going on here, what should you do, and when should you do it?

What’s Going On: 32-bit and 64-bit Apps

Over a decade ago, Apple started to transition all the chips used in Macs, along with macOS itself, from a 32-bit architecture to a 64-bit architecture. Without getting into technical details, 64-bit systems and apps can access dramatically more memory and enjoy significantly faster performance.

Apple knew it would take years before most people were running 64-bit hardware and 64-bit-savvy versions of macOS, so it allowed macOS to continue running older 32-bit apps. However, maintaining that backward compatibility has a cost, in terms of both performance and testing, so at its Worldwide Developer Conference in 2017, Apple warned developers that High Sierra would be the last version of macOS to support 32-bit apps “without compromise.” At the next WWDC in June 2018, Apple announced that macOS 10.14 Mojave would be the last version of macOS to run 32-bit apps.

Happily, the only “compromise” for 32-bit apps in Mojave is the warning dialog, which appears every 30 days when you launch an older app. But the writing is on the wall: 32-bits apps will cease working in macOS 10.15.

How Do You Identify 32-bit Apps?

Apple provides a tool to help you find 32-bit apps. Follow these steps:

  1. From the Apple menu, choose About This Mac and then click the System Report button.
  2. In the System Information utility that opens, scroll down to Software in the sidebar and select Applications. It may take a few minutes to build the list of every app on all mounted drives.
  3. When it finishes, click the 64-bit column header (No means 32-bit; Yes means 64-bit) to sort the list, and select an app to see its details in the bottom pane.

This technique works in both High Sierra and Mojave, but in Mojave, System Information includes a better-formatted section, called Legacy Software, that also provides a list of 32-bit apps. However, this list may be smaller because it includes only those apps that you’ve launched. Since it’s likely that you open old 32-bit apps only occasionally, you can’t trust the Legacy Software list to be complete.

If you find System Information’s Applications list overwhelming, check out the free 32-bitCheck utility from Howard Oakley. It performs exactly the same task but lets you focus on a particular folder and save the results to a text file for later reference.

What’s Your Next Step?

Once you know which apps won’t work in macOS 10.15, you can ponder your options. Luckily, you have some time. We expect Apple to release macOS 10.15 in September 2019, but you don’t need to upgrade right away—in fact, we recommend that you wait a few months after that to allow Apple time to fix bugs.

That said, we do encourage upgrading eventually, and if you buy a new Mac after September 2019, it will come with macOS 10.15. So you need to establish a plan—it’s better to know what you’re going to do than to be forced into action if you have to replace your Mac on short notice. For each 32-bit app on your Mac, you have three options:

  • Delete it: It’s not uncommon to have old apps that you haven’t used in years and won’t miss. There’s no need to waste drive space on them in macOS 10.15.
  • Upgrade it: Apps in active development will likely have a new version available. The main questions are how much the upgrade will cost and if there are compatibility issues associated with upgrading. You can upgrade at any time, although it’s likely worth waiting until you’re ready to move to macOS 10.15 to minimize costs. The apps that cause the most irritation here are things like the Adobe Creative Suite—Photoshop, Illustrator, and InDesign—that require switching to a monthly subscription.
  • Replace it: If no upgrade is available, the cost of upgrading is too high, or upgrading comes with other negatives, it’s time to look for an alternative. This can take some time, so it’s worth starting soon to ensure that the replacement will provide the features you need before macOS 10.15 forces the decision.

Social Media: Have you seen dialogs warning that an app isn’t optimized for your Mac? Here’s what’s going on, what you should do, and when you should do it:

What Are All These New Privacy Request Dialogs in Mojave?

With macOS 10.14 Mojave, Apple has beefed up the Mac’s privacy so it more closely resembles privacy in iOS. You’ve noticed that when you launch a new app on your iPhone or iPad, it often prompts for access to your photos or contacts, the camera or microphone, and more. The idea behind those prompts is that you should always be aware of how a particular app can access your personal data or features of your device. You might not want to let some new game thumb through your photos or record your voice.

macOS has been heading in this direction, but Mojave makes apps play this “Mother, May I?” game in more ways. As a result, particularly after you first upgrade, you may be bombarded with dialogs asking for various permissions. For instance, when you first make a video call with Skype, it’s going to ask for access to the camera and the microphone. Grant permission and Skype won’t have to ask again.

Skype’s requests are entirely reasonable—it wouldn’t be able to do its job without such access. That applies more generally, too. In most cases, apps will ask for access for a good reason, and if you want the app to function properly, you should give it access.

However, be wary if a permission dialog appears when:

  • You haven’t just launched a new app
  • You aren’t doing anything related to the request
  • You don’t recognize the app making the request

There’s no harm in denying access; the worst that can happen is that the app won’t work. (And if it’s malicious, you don’t want it to work!) You can always grant permission later.

To see which permissions you’ve granted or denied, open System Preferences > Security & Privacy > Privacy. A list of categories appears on the left; click one to see which apps have requested access. If you’ve granted access, the checkbox next to the app will be selected; otherwise it will be empty.

You’ll notice that the lock in the lower-left corner is closed. To make changes, click it and sign in as an administrator when prompted.

Most of these categories are self-explanatory, but it might not always be obvious why an app wants permission. In the screenshot above, for instance, Google Chrome has been granted access to the Mac’s camera. Why? So Google Hangouts and other Web-based video-conferencing services can work.

There are five categories (including three not showing above) that could use additional explanation:

  • Accessibility: Apps that request accessibility access want to control your Mac. In essence, they want to be able to pretend to click the mouse, type on the keyboard, and generally act like a user. Utility and automation software often needs such access.
  • Full Disk Access: This category is a catch-all for access to areas on your drive that aren’t normally available to apps, such as data in Mail, Messages, Safari, Home, and more, including Time Machine backups and some admin settings. Backup and synchronization utilities may need full disk access, in particular. An app can’t request full disk access in the normal way; you must add it manually by clicking the + button under the list and navigating to the app in the Applications folder.
  • Automation: The Mac has long had a way for apps to communicate with and control one another: Apple events. An app could theoretically steal information from another via Apple events, so Mojave added the Automation category to give you control over which apps can control which other apps. You’ll see normal permission requests, but they’ll explain both sides of the communication.
  • Analytics: The Analytics privacy settings are completely different—they let you specify whether or not you want to share information about how you use apps with Apple and the developers of the apps you use. For most people, it’s fine to allow this sharing.
  • Advertising: Finally, the Advertising options give you some control over the ads that you may see in Apple apps. In general, we recommend selecting Limit Ad Tracking, and if you click Reset Advertising Identifier, any future connection between you and the ads you’ve seen will be severed from past data. There’s no harm in doing it. It’s worth clicking the View Ad Information and About Advertising and Privacy buttons to learn more about what Apple does with ads.

So if you’ve been seeing repeated requests for permission after you upgraded to Mojave, now you know why these dialogs keep popping up. They’re a bit annoying at first, but the added privacy is worthwhile, and once you’ve granted permission to an app, you shouldn’t hear from it again.


Social Media: macOS 10.14 Mojave changes how privacy works on the Mac by making apps ask for permission to use the camera, microphone, and quite a bit more. Here’s how this works and what you should do when prompted.

Understanding Dark Mode in macOS 10.14 Mojave

The feature Apple is promoting most heavily with macOS 10.14 Mojave is Dark mode, which the company advertises as “a dramatic new look that helps you focus on your work… as toolbars and menus recede into the background.” Let’s look at what Apple has done with Dark mode, after which you’ll have a better idea of what to think about while trying it.

Enable Dark Mode

First, to turn Dark mode on, go to System Preferences > General and click the Dark thumbnail to the right of Appearance. Mojave immediately switches to Dark mode, turning light backgrounds dark and swapping the text color from dark to light.

While you’re in System Preferences, click over to the Desktop & Screen Saver preference pane. If you scroll down in the Desktop Pictures list, you’ll discover a bunch of new wallpapers that blend well with Dark mode.

Dark Mode Support and Controls

You’ll notice that the color change takes place instantly not just in the Finder, but also in any apps that support Dark mode. Most of Apple’s apps support Dark mode and third-party developers are rapidly adding support to their apps as well. However, Dark mode requires explicit support from apps, so older apps that aren’t being updated will maintain their standard dark-on-light color schemes.

Some apps, such as Maps and Mail, give you additional options that change just how dark they get. In Maps, choose View > Use Dark Map to toggle between a dark map style and the familiar map style that mimics a paper map. Similarly, in Mail, go to Mail > Preferences > Viewing and deselect “Use dark backgrounds for messages” to return to a white background.

If you generally like Dark mode but have trouble reading light text on a dark background due to the reduced contrast, you may be able to choose a different font or style in the app’s preferences that makes the text more readable. Apps like Mail give you a fair amount of that sort of control.

For even more control over contrast, open System Preferences > Accessibility > Display. There you’ll find a Display Contrast slider that lets you make text lighter and backgrounds darker. You can also select Reduce Transparency to make it so items like the Dock and menu bar are solid colors, rather than allowing the background to bleed through. To separate dark and light further, select Increase Contrast, which increases the brightness of divider lines as well.

The Dark Side of Dark Mode

Contrast is necessary for pulling out fine details, but too much contrast can be uncomfortable or even painful—think about how you feel when someone turns on a bright light in a previously dark room. For visual comfort, it’s usually best to match your screen with the lighting of your surroundings. That’s why people who often work at night or with the window blinds down like dark modes—a bright screen seems brighter in a dimly lit room. That’s the theory behind the traditional dark text on a light background too, since the room will be quite light during the day.

So Dark mode can run into two problems. First is that using it during the day or in a brightly lit room may create an uncomfortable contrast between the screen and its surroundings. Controlling your room lighting can eliminate this as an issue. Second and more troubling, even apps that support Dark mode may have large content areas that are bright white, creating a strong contrast between the content area and the rest of the app. Many Web sites in Safari have this effect, as do documents in apps like Pages and Numbers. There’s no way around this scenario.

Even if Dark mode isn’t perfect, it’s worth a try if you have trouble looking at bright screens. Regardless, if it goes too far for you, one of the new dark wallpapers may be easier on your eyes. While most people aren’t overly light sensitive, a non-trivial percentage of the population is, particularly those who suffer from migraines or who have endured concussions, and those with a variety of ocular conditions. And if you’re on the other end of the spectrum—if Dark mode looks dirty and is hard to read—just stick with the traditional Light mode.

Being an Apple User Means You’re Not the Product

There’s an Internet saying: “If you’re not the customer, you’re the product.” The point is that, if you’re getting a service for free, the company providing it sees you not as a customer, but as a product to sell, generally to advertisers.

This is how Google, Facebook, and Twitter operate. They provide services for free, collect data about you, and make money by showing you ads. In theory, the more that advertisers know about you, the better they can target ads to you, and the more likely you’ll be to buy. Personalized advertising can seem creepy (or clueless, when it fails), but it isn’t inherently evil, and we’re not suggesting that you stop using ad-supported services.

This ad-driven approach stands in stark contrast to how Apple does business. Apple makes most of its money by selling hardware—iPhones, Macs, and iPads, primarily. Another big chunk of Apple’s revenue comes from App Store and iTunes Store sales, iCloud subscriptions, and Apple Pay fees. Knowing more about you, what Web pages you visit, what you buy, and who you’re friends with doesn’t help Apple’s business, and on its Privacy page, Apple says bluntly, “We believe privacy is a fundamental human right.”

Of course, once your data is out there, it can be lost or stolen—in June 2018, a security researcher discovered that the online data broker Exactis was exposing a database containing 340 million records of data on hundreds of millions of American adults. Ouch!

Let’s look at a few of the ways that Apple protects your privacy.

Siri and Dictation

The longer you use Siri and Dictation, the better they work, thanks to your devices transmitting data back to Apple for analysis. However, Apple creates a random identifier for your data rather than associating the information with your Apple ID, and if you reset Siri by turning it off and back on, you’ll get a new random identifier. Whenever possible, Apple keeps Siri functionality on your device, so if you search for a photo by location or get suggestions after a search, those results come from local data only.

Touch ID and Face ID

When you register your fingerprints with Touch ID or train Face ID to recognize your face, it’s reasonable to worry about that information being stored where attackers—or some government agency—could access it and use it for nefarious purposes. Apple was concerned about that too, so these systems don’t store images of your fingerprints or face, but instead mathematical signatures based on them. Those signatures are kept only locally, in the Secure Enclave security coprocessor that’s part of the CPU of the iPhone and iPad—and on Touch ID-equipped laptops—in such a way that the images can’t be reverse engineered from the signatures.

And, of course, a major goal of Touch ID and Face ID is to prevent someone from violating your privacy by accessing your device directly.

Health and Fitness

People with medical conditions can be concerned about health information impacting health insurance bills or a potential employer’s hiring decision. To assuage that worry, Apple lets you choose what information ends up in Health app, and once it’s there, encrypts it whenever your iPhone is locked. Plus, any Health data that’s backed up to iCloud is encrypted both in transit and when it’s stored on Apple’s servers.

App Store Guidelines

A linchpin in Apple’s approach to privacy is its control over the App Store. Since developers must submit apps to Apple for approval, Apple can enforce stringent guidelines that specify how apps can ask for access to your data (location, photos, contacts, etc.). This isn’t a blanket protection—for instance, if you allow a social media app Facebook to access your contacts and location, the company behind that app will get lots of data on your whereabouts and can even cross-reference that with the locations of everyone in your contact list who also uses the service.

In the end, only you can decide how much information you want to share with the likes of Google, Facebook, and Twitter, and only you can determine if or when their use of your details feels like an invasion of privacy. But by using Apple products and services, you can be certain that the company that could know more about you than any other is actively trying to protect your privacy.


Social Media: Many of the big Internet companies make their money by assembling a dossier of information about you and then selling advertisers targeted access to you. Luckily, that’s not true of Apple—here are a few of the ways Apple protects your privacy.
