Apple Seeds First macOS Sierra 10.12.2 Beta to Developers

Apple today seeded the first beta of an upcoming macOS Sierra update 10.12.2 to developers, just one week after releasing macOS Sierra 10.12.1 and more than a month after launching the new macOS Sierra operating system.

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.

macOS is still good. One of the few things that is still good. I'm sure Apple is hard at work wondering how best to **** it.

Every machine is different, but on my 2015 rMBP 13", it's the most stable macOS release I've ever used, and I've run everything since Lion on a handful of different machines.

Still can't auto-mount network shares without prompting for credentials (even if saved in keychain). Pretty lame bug. I'd verify that the bug report for it is still open...but, "An error has occurred. For assistance accessing Apple Bug Reporter, please contact Apple Developer Program Support."

It messed with my Photoshop and Illustrator performance. Did a fresh install and it got even worse. Not specifically Apple's fault, but still.

Kind of fed up with Apple atm.
