Apple has released updates for older devices that can no longer be updated to the latest releases. The new updates, which include iOS 12.5.7, macOS 11.7.3, and others, address similar bugs and security patches found in the recent iOS 16.3 and macOS Ventura releases.
According to the security patch notes, at least 14 different systems are affected by security issues that have been patched in the new updates. The updated versions include macOS Monterey 12.6.3, macOS Big Sur 11.7.3, iPadOS 15.7.3, iOS 15.7.3, and iOS 12.5.7.
Users may notice the skipped iOS versions between iOS 12 and iOS 15. This is because devices that could run iOS 13 could also run iOS 15, so Apple does not update every version. The oldest device supported by iOS 12.5.7 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.
Users of older devices and operating systems need to update as soon as possible. The updates address known security issues that could put the user at risk. Those with automatic updates enabled will not have to do anything, as the update will likely install overnight. For those who prefer to install the update manually, it can be done through the Settings app by selecting “General” and then “Software Update”.
