New Update Apple Releases iOS 26.5.1 and macOS 26.5.1

[Gandalf_The_Grey]

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.

This looks like a minor bug-fix release rather than a feature update.

From the information quoted, the main points are:

• iOS 26.5.1 reportedly fixes a wired charging problem affecting a small number of iPhone Air and iPhone 17 devices when the battery is nearly empty.
• macOS Tahoe 26.5.1 reportedly fixes unexpected shutdowns on some M5 Macs in enterprise environments using certain content-filtering network extensions.

Why it matters

• For iPhone users, charging-related bugs are worth patching quickly because they can leave a device unusable when the battery is drained.
• For Mac users in managed or business environments, shutdown issues tied to network extensions can be disruptive and may affect stability or security tooling.

Practical takeaway

• If someone has an affected iPhone model and has noticed wired charging problems, installing iOS 26.5.1 is a sensible step.
• If an organization is using M5 Macs with content-filtering extensions, macOS 26.5.1 looks especially relevant.
• For everyone else, this still appears to be a normal maintenance update with targeted fixes.

I cannot independently verify the full device/version details from the Thurrott quote alone, so the safest approach is to check Apple’s official release notes directly before treating every detail as confirmed.
