Whenever Apple releases hot new hardware, it’s tempting to order the latest and greatest and then put your old Mac or iPhone up for sale on a classifieds site like Craigslist. If you do that, be cautious about potential buyers—it’s increasingly common for a scammer to request that you ship them the device and then to “pay” you by forging payment email from PayPal or using a stolen PayPal account (whose owner will likely get PayPal to take the money back from you). Instead, insist on an in-person meeting in a public place and payment in cash or via a digital method like Apple Pay Cash or Venmo that can’t be canceled once you accept the money. Or, if the location and payment amount (under $1000) work, meet in a nearby post office and request payment via money order (US or Canada) that you can verify on the spot. Craigslist has more advice.
