It is as I suspected: AppleCare One does not correctly handle multiple user accounts in macOS. This is a known issue. No ETA for a fix. After days of receiving nonsensical 'you have 24 hours to comply' emails about his AppleCare One coverage, John finally discovered that AppleCare One cannot properly handle multiple user accounts in macOS, a limitation Apple acknowledges but has no timeline for fixing. He says the problem may also affect those with multiple accounts on an Apple TV, though there's little reason to have AppleCare for an Apple TV. Although full details aren't yet available, my guess is that the accounts must be associated with different Apple Accounts and accessed after signing up for AppleCare One. (For more details about the service in general, see '[2]Apple Unveils AppleCare One for Multiple-Device Protection,' 28 July 2025.) Apple's solution was less than ideal: cancel AppleCare One and sign up for individual device coverage instead. Adding insult to injury, Siracusa notes that these new plans will cost him $48 more per year than his original AppleCare+ coverage, which is no longer available. As compensation, Apple offered to let him pick an accessory worth up to $200. That's not ungenerous, but Apple wouldn't switch to a gift card, as he requested, forcing him to pick a $150 accessory for his wife that he wouldn't necessarily have bought otherwise. For now, if you use multiple user accounts on your Mac'which is common for developers, families sharing computers, and people who maintain separate work and personal environments'you should avoid AppleCare One. The service might make sense for those with simple account setups, but Mac power users should stick with traditional AppleCare+ plans until Apple addresses this limitation.
