Apple Releases macOS Sierra 10.12.3 With Graphics Fixes for 2016 MacBook Pro
Apple today released macOS Sierra 10.12.3, the third update to the macOS Sierra operating system that launched on September 20. macOS Sierra 10.12.3 comes over a month after the release of macOS Sierra 10.12.2, and has been in testing since December 14.
macOS Sierra 10.12.3 is a free update for all customers who are running macOS Sierra. The update can be downloaded using the Software Update function in the Mac App Store.

No specific changes, bug fixes, or feature additions were discovered during the beta testing process, and Apple only said the update "improves the stability, compatibility, and security of your Mac." Apple's release notes paint a more complete picture, stating that the update improves graphics switching for the new 15-inch MacBook Pro, fixes issues with Adobe Premiere, and includes important fixes for Preview.
The macOS Sierra 10.12.3 Update improves the stability and security of your Mac, and is recommended for all users.
This 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.
