Apple today released macOS Sierra 10.12.2, the second update to the macOS Sierra operating system that launched on September 20. macOS Sierra 10.12.2 comes two months after the release of macOS Sierra 10.12.1, and has been in testing since October 31.

macOS Sierra 10.12.2 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.



macOS Sierra 10.12.2 includes new emoji, introducing dozens of Unicode 9 characters like selfie, face palm, owl, shark, avocado, pancakes, bacon, and more, plus there are new profession emoji available in both male and female genders.

Apple has also updated the artwork on many existing emoji to make them look more realistic, and new color explosion wallpapers -- from the iPhone marketing materials -- have been introduced.

Along with these outward-facing changes, the 10.12.2 update includes several important bug fixes.
