Apple Seeds Fourth macOS Sierra 10.12.2 Beta to Developers [Updated]

Apple today seeded the fourth beta of the upcoming macOS Sierra 10.12.2 update to developers, two weeks after releasing the third 10.12.2 beta and a month after the public release of macOS 10.12.1.

macOS Sierra 10.12.2 beta 4 is available for download through the Apple Developer Center or through the software update mechanism in the Mac App Store.

macos-10-12-2-beta
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 are available in both male and female genders. Apple has also updated the artwork on many existing emoji, adding detail and design elements to make them look less cartoonish and more realistic.

There are few other outward-facing 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 surfaced 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 4 is also available for public beta testers.

The face palm emoji seems especially relevant.

Nice to see "outward-facing changes aside from the addition of new emoji". Courageous.

What turd MacOS Sierra is. After spending all that effort to clean up the bugs in Mavericks & Yosemite with El Capitan, they release a fresh stinking pile of buggy software full of emojis.

Wish I never upgraded. The 3 positive benefits of MacOS Sierra is their space-reducing feature, ApplePay, and App Tabs, and none of these are dramatic user experience improvements. Other than that, 3rd party software suffices for any of their new 'features'.

Siri? - Used once just to see how it worked.

Universal Copy-Paste? - I have 2 apps that can do that

Unlock via TouchID? - I have an app for that and I don't have to buy a new MacBook to do it

Desktop & Documents folder on all devices? - Even more fragmentation? No thanks. As if the iCloud environment isn't already confusing enough.

ApplePay? - Neat, haven't used it yet

Photos? - More bloated mac apps? No thanks

Emojis? - Everything thats wrong with the world today

iTunes? - The worst app on Mac becomes even worse

Tabs? - Neat, haven't used it yet

I still can't plug in my HDMI monitor without the Fan buzzing like a Category 5 hurricane (mid2102 MBP 15" Retina) .

Stick with El Capitan if you haven't upgraded.

Dear God, what a cluster**** Apple is these days. Tim and his buffoon buddies have six months to release something that equates to a decent desktop computer, or then my $many thousands go to a PC manufacturer. Emojis... I mean what the actual ****? So glad I stuck with El Capitan.

And I agree with one of the posters above. Tim Cook really has to go.
