Apple releases macOS Sierra 10.12.3 update



Apple has just recently released an update to macOS Sierra. While mostly a bug-fix update, macOS Sierra 10.12.3 also graphics switching issues that were reported by users of the 15-inch MacBook Pro.

With this update, Apple has also provided fixes for graphics-related issues experienced by users of the MacBook Pro with Touch Bar. These users experienced a major overheating of their machines when using Adobe Premier Pro. This update should ensure the problem is properly resolved. This version of macOS also provides a few security updates for users.

Another contentious issue was the reportedly dismal battery life of the new MacBook Pro. Apple has narrowed down the problem to a bug in Safari which used far too many resources and hence drained battery life. This update of macOS comes with a bug fix that cleans up this issue. Apple initially addressed this bug with the beta release of macOS 10.12.3, which lead to Consumer Reports finally recommending the new MacBook Pro.

Here’s a full breakdown of the update:

  • Improves automatic graphics switching on MacBook Pro (15-inch, October 2016).
  • Resolves graphics issues while encoding Adobe Premiere Pro projects on MacBook Pro with Touch Bar (13- and 15-inch, October 2016).
  • Fixes an issue that prevented the searching of scanned PDF documents in Preview.
  • Resolves a compatibility issue with PDF documents that are exported with encryption enabled.
  • Fixes an issue that prevented some third-party applications from correctly importing images from digital cameras.
