iOS 12.5.5 Security Update Released for Older iPhone & iPad

Sep 23, 2021 - 1 Comment

iOS 12.5.5

Apple has released iOS 12.5.5 for users with older iPhone, iPad, and iPod touch devices that are incapable of running iOS 15 and iPadOS 15.

iOS 12.5.5 includes important security fixes and is therefore recommended to install for all devices that can get the update.

Separately, Mac users running macOS Catalina will find Security Update 2021-006 Catalina available for Macs that are not yet running Big Sur.

Installing iOS 12.5.5 on iPhone & iPad

iOS 12.5.5 is only available for iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch 6th generation. Other devices will not find the update available.

It is recommended to backup your device before installing any software update.

  1. Open the “Settings” app on iPhone or iPad
  2. Go to “General” and then to “Software Update”
  3. Install iOS 12.5.5 when it shows as available

The update will require the device to reboot.

Newer model iPhone and iPad devices will instead continue to find iOS 15 and iPadOS 15 available, or the iOS/iPadOS 14.8 releases.
