Also makes Mac App Store tweaks to support "future software updates."

Apple has just release the macOS 10.12.5 update for Sierra, the fifth major update since the operating system was released in September of 2016. The update is available for all Macs that support Sierra, and should also be included in all new downloads of the Sierra installer from the Mac App Store.

Unlike macOS 10.12.4, which added a notable new feature in Night Shift, version 10.12.5 focuses on fixing bugs, improving support for new software, and addressing a long list of security vulnerabilities that overlaps quite a bit with those addresses by the iOS 10.3.2 update. Here's the full list of fixes listed in the release notes:

  • Fixes an issue where audio may stutter when played through USB headphones
  • Enhances compatibility of the Mac App Store with future software updates
  • Adds support for media-free installation of Windows 10 Creators Update using Boot Camp

The update can be downloaded through the Mac App Store, and should also be made available on the macOS downloads page sometime soon. The security-related fixes have also been released in update 2017-002 for both Yosemite and El Capitan, for those of you who are still using older versions of macOS.
