Apple Seeds Third macOS Sierra 10.12.2 Beta to Developers [Update: Public Beta Available]

Apple today seeded the third beta of the upcoming macOS Sierra 10.12.2 update to developers, one week after releasing the second 10.12.2 beta and three weeks following the public release of macOS 10.12.1.

The third macOS Sierra 10.12.2 beta is available for download through the Apple Developer Center and through the software update mechanism in the Mac App Store, but the Mac App Store appears to be having trouble updating apps for some people at the moment.

macOS Sierra 10.12.2 includes new emoji, introducing Unicode 9 characters like clown face, selfie, face palm, fox face, owl, shark, butterfly, avocado, pancakes, croissant, bacon 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.

There are few other changes aside from the addition of new emoji, but the 10.12.2 update also likely includes many bug fixes and performance enhancements to address issues that have popped up since the release of macOS Sierra 10.12.1.

Available since September, macOS Sierra is the latest Mac operating system. It includes Siri support, Apple Pay for the web, Universal Clipboard, Apple Watch auto unlocking, improved iCloud Drive integration, Picture-in-Picture multitasking, and dozens of smaller features that can be found in our macOS Sierra roundup.

Update: macOS Sierra 10.12.2 beta 3 is also available for public beta testers.

But it's hilarious. I bet Juli giggles every time she posts about macOS updates. "We've got more and prettier emojis!!!!! It's not clear if there are any other updates". heartemoji.gif

What I need to know is did they stop switching Optimize Storage on by default and does Photos still take six years to scan a 30,000 photo library when using iCloud.

Not sure how better battery life on your MacBook will result in longer times between charging your phone.
