Apple releases iOS 26.5.1 and macOS 26.5.1

Apple Patches Critical Charging Bug with iOS 26.5.1 and macOS 26.5.1

Apple just rolled out a minor update, iOS 26.5.1, and while it isn’t packed with flashy new features, it is a vital download for anyone rocking the latest hardware. This isn’t one of those updates that changes how your phone looks or adds new emojis; instead, it is a surgical strike against a particularly frustrating bug.

According to the official changelog, some iPhone 17 and iPhone Air users were hitting a wall when trying to charge their devices via a cable. The kicker? It only seemed to happen when the battery was already critically low—exactly when you are most desperate for a power outlet. Apple mentions that only a “very small number” of people ran into this, but if you have been staring at a dead phone that refuses to juice up, this update is your lifesaver.

Fixes for macOS and the M5 Chip

Mac users were not left out of the maintenance cycle. Apple also dropped macOS 26.5.1 to address a specific issue affecting enterprise environments. Apparently, Macs powered by the M5 chip were suffering from unexpected shutdowns when using certain network extensions for content filtering. If your workstation has been cutting out in the middle of a project, this patch should stabilize things.

Looking Toward the Future: iOS 27

While these point-releases keep the current gear running smoothly, the real excitement is just a few days away. On June 8, Apple is expected to pull back the curtain on iOS 27 and macOS 27. We will likely see the full public release of those major operating systems this fall, following the usual September iPhone launch cycle.

For now, if you are on an iPhone 17 or an M5 Mac, head to your settings and grab these fixes today to keep your hardware running as it should.
