Apple Seeds First macOS Sierra 10.12.2 Beta to Developers
macOS Sierra 10.12.2 beta 1 is available for download through the Apple Developer Center and through the software update mechanism in the Mac App Store. A public beta will likely be available for public beta testers later this week.
It is not yet clear what improvements the second update to macOS Sierra will bring, but it will focus on bug fixes and performance enhancements to address issues that have popped up since the release of macOS Sierra 10.12.1.
macOS Sierra includes new emoji introducing Unicode 9 characters like clown face, drooling face, selfie, face palm, fox face, owl, shark, butterfly, avocado, pancakes, croissant, and more, plus many profession emoji available in both male and female genders.
Apple has also updated the artwork on many existing emoji, adding detail and making them look less cartoonish and more realistic.
