Yes, we know we’re still on macOS 26. In 2025, Apple announced macOS 27 would be the last version to support Rosetta for most Intel-based apps. (Beyond that, Apple will maintain a subset of Rosetta functionality for older, unmaintained gaming titles.) This fact has become relevant because in the just-released macOS 26.4, when you launch apps that rely on Rosetta for Intel compatibility, macOS may start warning you that they won’t open in a future version of macOS. These warnings are just reminders—nothing will change until you upgrade to macOS 28, probably in late 2027 or 2028, giving you plenty of time to find replacements. To identify Intel-based apps now, open System Information from the Utilities folder in your Applications folder, select Applications in the sidebar, and click the Kind column header to sort all your Intel apps together. iMazing’s free Silicon app does the same thing with a nicer interface.

Social Media: Running macOS 26.4? You may start seeing warnings about Intel-based apps not opening. They won’t stop working until macOS 28, but now’s the time to find replacements. Here’s how to identify which apps need attention.
Apple Music subscribers running iOS 26.4 can use the new Playlist Playground feature to create AI-generated playlists tailored to any mood, genre, activity, or era. To try it on your iPhone, open the Music app, tap the Library tab, tap the + button, then tap Create New Playlist. Instead of manually adding songs, tap the search field and enter a natural language description like “songs from a high school dance in the early 1980s” or “positive workout music from after 2010.” Playlist Playground will generate a playlist of songs based on your prompt. You can refine it by giving additional prompts, rearranging songs by dragging the hamburger buttons, or tapping Add Songs at the bottom. When you’re satisfied, tap the checkmark button at the top right to keep the playlist. Playlist Playground requires Sync Library to be enabled in Settings > Apps > Music, and the feature is currently available only in the U.S. and in English.

If your Mac starts typing unexpected characters—or rejects a password you know is correct—check to see if the Input Source menu appears in the upper-right corner of the screen, indicating that your Mac has more than one keyboard layout available for writing in other languages. Accidentally switching from the standard U.S. keyboard (or whatever you regularly use) to another layout—like the French ABC – AZERTY, which swaps the A and Q keys, among others—can cause keystrokes to produce different characters than expected. This key swapping is particularly confusing in password fields, where you can’t see what’s being typed. To fix it, click the Input Source menu and choose your default. To prevent this problem from recurring, go to System Settings > Keyboard, click Edit next to Input Sources, and delete any keyboard layouts you don’t use. You can also change what the Globe key does in System Settings > Keyboard—you can prevent accidental layout changes by switching it from Change Input Source to Show Emoji & Symbols, Start Dictation, or Do Nothing.

We recently helped a client set up an external boot drive on a Mac mini for testing, but the installation kept failing near the end with vague errors. We tried different cables, swapped drives, and more, to no avail. On a hunch, we moved the SSD to a different USB-C port, and the installation completed on the next attempt. But the port wasn’t bad—it was just the wrong port. Here’s what we mean.
All the USB-C ports on a Mac look identical, but they don’t all behave the same way. On Macs with Apple silicon and Intel-based Macs with the T2 chip, Apple designates one port as the DFU (device firmware update) port. Most of the time, this distinction doesn’t matter—you can plug a device into any port, and it’ll work normally. But for certain tasks, using the wrong port can cause mysterious failures that waste hours of troubleshooting time.
Note that we say “USB-C” here, even though in most cases, these are Thunderbolt ports. However, Thunderbolt uses the USB-C connector, and Apple refers to the ports as USB-C ports, so we’re following Apple’s lead.
The DFU port exists for one specific purpose: reviving or restoring your Mac’s firmware using another Mac and the Apple Configurator app. This recovery procedure requires connecting a USB-C cable (not a Thunderbolt cable!) to the DFU port. It’s extremely uncommon to need to revive a Mac in this way, but it might be necessary if the Mac starts up to an exclamation point in a circle, starts up to a blank screen, shows the status indicator light pattern for firmware recovery mode, or has problems installing macOS.
For most everyday tasks, the DFU port should work like any other USB-C port. However, Apple has documented one notable exception on Macs with Apple silicon: when installing or updating macOS on an external drive, avoid using the DFU port. If your external drive is connected to it during installation, the process may fail partway through, often without a useful error message and certainly without a clear “Connect your drive to a different port” message. You might see vague notifications like “Some updates could not be installed” or cryptic errors like “com.apple.OSInstallerSetup.error 702.” After installation or updating completes, you can connect your external drive to any port, including the DFU port.
We’ve also heard of situations where seemingly inexplicable problems, such as errors from an Apple SuperDrive attached to a Thunderbolt dock, were resolved by switching to a different port. It wasn’t always clear which port was responsible, but it’s always worth trying a different one if you have trouble.
How do you figure out which USB-C port is the DFU port? Apple maintains a support document describing the DFU port locations for each Mac model. The location varies by model and, within the same model, sometimes by generation. Apple does not explain why a particular port is designated as the DFU port or provide another way to identify it. All you can do is refer to Apple’s documentation.

Unfortunately, users have found errors on that page in the past, so if you’re experiencing unexplained installation failures or other errors, try a different port even if you believe you’re using the correct one.
For everyday use—connecting displays, drives, docks, and other peripherals—you shouldn’t need to think about which port you’re using. The only time you must use the DFU port is when reviving or restoring a very unhappy Mac.
However, if you’re setting up an external boot drive or updating macOS on an external drive, take a moment to identify your Mac’s DFU port and plug your drive into a different one. And if a peripheral, even if it’s connected through a dock, behaves inexplicably, treat the port itself as a variable. Before troubleshooting cables, drives, or software, move the connection to another USB-C port. This simple step can save you from frustrating troubleshooting sessions where everything appears to work but ultimately fails.

When a Web browser has many tabs open, it can be hard to find the one playing audio if you need to silence it. Worse, when a browser relaunches, it can be tough to identify and silence all the tabs that have automatically started playing audio. Happily, all browsers can help. Tabs with active audio show a speaker icon next to their names; click it to mute the audio. These speaker icons are easier to spot in browsers that display tabs vertically rather than horizontally across the top, where space constraints may prevent the speaker icons from appearing. Safari provides an additional option: a speaker icon on the right side of the address bar (see the top screenshot). Click it to mute all audio, or Control-click it to see which tabs are playing audio. Chromium-based browsers—including Google Chrome, Brave, and Microsoft Edge—display a musical note icon in the upper-right corner of the toolbar (bottom screenshot). Click it to open playback controls and stop playback.

Social Media: Drowning in open tabs and can’t find the one playing sound? Look for the speaker icon on the tab itself, or use Safari’s address bar icon or Chrome’s music note for quick control.
In iOS, iPadOS, and macOS 26, Apple added an option in the Messages app to filter messages from unknown people and those marked as spam by the carrier. To enable filtering, open Messages, tap the Filter
button in the upper-right corner, tap Manage Filtering, and turn on Screen Unknown Senders and Filter Spam. Once those are enabled, the Filter menu gains two new options: Unknown Senders and Spam. If a text from an unknown person comes in, the main app icon will get a red badge, but you won’t see the new message in the usual list. Instead, use the Filter menu—which also gets a blue badge—to switch to Unknown Senders or Spam and look in those lists. The Phone app works similarly—enable call filtering in Settings > Apps > Phone under Call Filtering, and unknown callers will appear in separate lists accessible via the Filter button in the Phone app’s Recents or Calls views. To move a conversation out of Unknown Senders, tap Mark as Known.

Social Media: Missing texts from unknown numbers? iOS 26 filters them into hidden lists. Here’s where to find them in the Messages app—and how to mark senders as known so you don’t miss important messages. PS: The same applies to calls in the Phone app.
Sadly, not all websites and apps support Apple Pay, so we’ve become accustomed to manually entering our credit card information into fields, like animals. No longer! In iOS 26, the Wallet app now supports AutoFill. If you need to add a card—those set up with Apple Pay are already available—open Wallet, tap the three-dot menu in the top-right corner, tap AutoFill, then tap Add Card. You can scan the card with your camera or enter details manually. Then, whenever you’re checking out on a website or in an app that doesn’t support Apple Pay, tap a payment field. You may be able to select a saved card from the suggestions above the keyboard, or you may have to tap in the field to bring up the text menu, and tap AutoFill > Credit Card (below left). When you invoke AutoFill from above the keyboard, your card number, expiration date, and security code will be automatically entered. Using the menu requires tapping the blue text for the field you want to fill (below right).

Apple has updated its Studio Display with an improved 12-megapixel Center Stage camera with Desk View support, two Thunderbolt 5 ports, and improved bass from its six-speaker system—all for the same $1,599 starting price. More significantly, Apple introduced the Studio Display XDR at $3,299, bringing professional-grade HDR technology to a broader audience at a much lower price than the $5,000 Pro Display XDR it replaces. The Studio Display XDR features a 27-inch 5K panel with mini-LED backlighting, 2304 local dimming zones, up to 2000 nits of peak HDR brightness, a 1,000,000:1 contrast ratio, and a 120 Hz refresh rate with Adaptive Sync. Both displays require macOS 26.3.1 Tahoe and work with all Apple silicon Macs.

Social Media: Apple’s new $3,299 Studio Display XDR brings mini-LED, HDR, and 120 Hz to a 27-inch 5K display—pro display tech at a far more accessible price. The standard Studio Display also gets a refresh with a better camera and Thunderbolt 5.
Sometimes you just don’t want your phone to ring, chirp, or even vibrate. Maybe you’re asleep, in an important meeting, having dinner with family, meditating, playing a game, or simply enjoying some quiet time.
Apple’s Focus feature on the iPhone, iPad, and Mac can silence those interruptions, but Focus is considerably more complex than the straightforward Do Not Disturb feature it replaced in 2021. Misconfiguring Focus such that it activates unexpectedly can cause you to miss important calls, messages, and other notifications.
Focus lets you create customized notification environments that block unwanted interruptions while allowing important ones through. You can have a Focus for different situations—when you’re at work, eating dinner, at the gym, and more—each with its own rules about when it activates and which people and apps can reach you.
When a Focus is active, it can:
Focus can share your settings across all your Apple devices, which saves you from having to configure it on each device but can also create confusing interactions.
Apple provides three essential Focus modes that cover most people’s needs:
For further customization, you can create additional Focus modes—Apple suggests modes for Gaming, Mindfulness, Personal, Reading, and Work. For instance, if you take a spin class every Tuesday at noon and yoga on Thursdays at 7 AM, you could create a Focus for Working Out that would automatically activate during those times.
To set up a Focus, go to Settings > Focus on your iPhone or iPad, or System Settings > Focus on your Mac. Select the Focus you want to configure or create a new one, then:




While Focus is powerful, its complexity can create unpredictable behavior. Here are common pitfalls to avoid:

To get the benefits of Focus without the confusion:
Focus is a powerful tool for managing the constant stream of notifications from our devices, but it requires careful configuration. When in doubt, keep it simple: Sleep to protect your sleeping hours, Driving to block distractions in the car, and Do Not Disturb for ad hoc appointments and performances may be all you need.
