macOS 10.12.3 fixes graphics switching problems with new 15“ MacBook Pros

In addition to minor updates for iOS, watchOS, and tvOS, Apple has released version 10.12.3 of macOS Sierra to the public today. The update is available through the Mac App Store and will be available later today on Apple's Downloads page; new copies of the Sierra installer downloaded after today should also include the update.

Compared to 10.12.2, today's update is pretty limited in scope. Apple is still making some fixes specific to the new MacBook Pros, particularly to the graphics switching mechanism of the 15-inch model (though we have no specific information about how it has been tuned for this update). Graphics problems with Adobe Premiere Pro projects have been fixed in both the 13- and 15-inch models.
