Quote:Apple released today iOS 26.5.1 to address charging issues on the iPhone Air and iPhone 17 models. The company also issued macOS Tahoe 26.5.1 (What's new in the updates for macOS Tahoe 26 - Apple Support), which includes a fix for an unexpected shutdown issue affecting enterprise users with M5 Mac models.

iOS 26.5.1 comes three weeks after the release of iOS 26.5, which added support for end-to-end encrypted RCS messaging and suggested places in Apple Maps. In the release notes for iOS 26.5.1, Apple explained that “this update addresses an issue for a small number of users that may prevent wired charging on iPhone Air and iPhone 17 models when the battery is nearly drained.”

For Mac users, macOS 26.5.1 “addresses an issue for enterprise users where Mac computers with an M5 chip could unexpectedly shut down when using certain content-filtering network extensions.” Apple refreshed its entire MacBook lineup with M5 chips between fall and spring, but the Mac Mini and Mac Studio have yet to be updated with the latest silicon.
