# macOS: improved data redaction fixes logging flaw exposing sensitive user data

A logging component on macOS recorded data that should have been redacted, so an app could read sensitive user information. Apple fixed it in macOS Golden Gate 27, Sequoia 15.8.2 and Tahoe 26.7.2.

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

## How to check

- Check the installed macOS version with `sw_vers -productVersion` and compare it with the fixed releases.
- unknown for any further local check; the sources do not describe a file or setting to inspect.

## Fix

- Update macOS to `15.8.2` (Sequoia), `26.7.2` (Tahoe), or Golden Gate 27 or later.
