Apple has provided iOS 12.5.7, macOS 11.7.3, and other updates for older devices that can’t be updated to the latest releases. AppleInsider reports: The new updates are for users still using older devices and operating systems and address similar bugs and security patches available in the recent iOS 16.3 and macOS Ventura releases. The security patch notes list at least 14 different systems affected by security issues that have been patched. The new update versions are: iOS 12.5.7, iOS 15.7.3, iPadOS 15.7.3, macOS Big Sur 11.7.3, and macOS Monterey 12.6.3.
Users may note the skipped iOS versions between iOS 12 and iOS 15. Those are due to where devices were cut off from updating. Every device that could run iOS 13 could run iOS 15, so Apple doesn’t update every version. The oldest device supported by iOS 12.5.7, for example, is the iPhone 5s, which was released in September 2013. The oldest Macs supported by macOS Big Sur are the 2013 MacBook Air, Mac Pro, and MacBook Pro. Anyone capable of updating these new updates to the older operating systems should do so as soon as possible. The update addresses known security issues that could put the user at risk.
