Monday was a good day for fans of small Apple updates. Early in the morning, we got the 2nd-generation AirTag, which is visually identical to the original model but adds a larger speaker and better tracking. Then it delivered iOS 26.2.1, iPadOS 26.2.1, and watchOS 26.2.1 to support the new accessory. Finally, Apple also announced the 2026 Black History Month Apple Watch band.
But even if you don’t have an iOS 26 iPhone and have no intention of buying a new AirTag, Apple has something for you, too. Alongside the 26 releases, Apple has also updated several of its older operating systems, some for the first time in years. They include: iOS/iPadOS 18.7.4, iOS/iPadOS 16.7.13, iOS/iPadOS 15.8.6, and iOS/iPadOS 12.5.8. (Of note, iPad OS wasn’t split apart from iOS until version 13, though Apple’s iOS 12.5.8 security page still references iPad OS.)
The update appears to be related to a specific issue. According to Apple’s “About iOS 12 Updates” page, iOS 12.5.78 “extends the certificate required by features such as iMessage, FaceTime, and device activation to continue working after January 2027.” Meanwhile, the iOS 16 update says it “provides important bug fixes and is recommended for all users.”
When iOS 13 arrived, it dropped compatibility for the iPhone 5S, iPhone 6, and iPhone 6 Plus, as well as the 2013 iPad Air and iPad Mini 3, so users of those phones should specifically take note.
To update to the latest version, head over to the Settings app, then General and Software Update, and follow the instructions.
