macOS Sierra 10.12 GM (16A322)

Description

macOS Sierra (version 10.12) is the upcoming thirteenth major release of macOS (previously OS X), Apple Inc.'s desktop and server operating system for Macintosh computers. The successor to OS X El Capitan, it is the first version of the operating system issued under the June 2016 rebranding as macOS. Following the California landmark-based naming scheme introduced with OS X Mavericks, Sierra was named after California's Sierra Nevada mountain range. Its major new features concern Continuity, iCloud, and windowing, as well as support for Apple Pay and Siri.


macOS Sierra will run on:
- iMac: Late 2009 or newer
- MacBook: Late 2009 or newer
- MacBook Air: 2010 or newer
- MacBook Pro: 2010 or newer
- Mac Mini: 2010 or newer
- Mac Pro: 2010 or newer


Sierra is the first version of macOS since OS X Mountain Lion, released in 2012, that does not run on all computers that the previous version supported. Developers have created workarounds to install macOS Sierra on some Mac computers that are no longer officially supported.
