Apple has just dropped a new macOS update — macOS 26.5.1 — and while it looks small on the surface, it actually fixes an important issue that some users definitely don’t want to ignore.
According to Apple, this update is not about new features at all. Instead, it focuses on stability and bug fixes.
The main fix addresses an issue where some Macs with M5 chips could unexpectedly shut down when using certain enterprise network security or content filtering tools.
