# Apple macOS: logic flaw lets an app bypass Gatekeeper checks

A logic flaw in macOS state management lets a malicious app bypass Gatekeeper's launch checks. An attacker who gets a crafted app onto a Mac can run it without the usual malware warnings.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `sw_vers -productVersion` on each Mac and compare against the fixed versions below.
- unknown for other checks; the sources do not say.

## Fix

- Update macOS to `27.2` (Golden Gate), `15.8.2` (Sequoia), or `26.7.2` (Tahoe).
