Apple Seeds Third Beta of macOS Sierra 10.12.3 to Developers

Apple today seeded the third beta of an upcoming macOS Sierra 10.12.3 update to developers, three weeks after seeding the second 10.12.3 beta and almost a month after releasing macOS Sierra 10.12.2, the second update to the macOS Sierra operating system.

The macOS Sierra 10.12.3 update is available for download through the Apple Developer Center or through the software update mechanism in the Mac App Store.

macos-10-12-3-beta
According to Apple's release notes, the 10.12.3 update "improves the stability, compatibility, and security of your Mac." No specific changes, bug fixes, or feature additions were discovered in the first two betas, but we'll update this post should any new features be found in the third beta.

Oftentimes, with bug fixes, it's hard to tell what's included until Apple supplies detailed release notes with a release. The previous update, macOS 10.12.2, introduced several important bug fixes to resolve battery life issues, fix graphics problems, and more.

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: The third public beta is also available.

Bring back the estimated time left on the battery.. the removal of that was such a troll move by Apple.

Edit 2: Dug a bit deeper, all Graphic Drivers are updated, including AMD, Intel and Geforce.

Cue the normal whining regarding stability. Those who signed up to the Beta programme only have themselves to blame if their system is unstable.

Me I don't run a new release of OS X (macOS) until the .4 release hence the reason I am still running OS X 10.11.6 El Capitan.

Stability is no trade off for new features.

Beta train! Chugga-chugga-chugga-chugga, woot! Woot!

(I can't install the beta anymore after reinstalling macOS from scratch last week. The beta enablement tool on developer.apple.com doesn't appear to work for some reason.)

That's why Sierra itself feels like it's a beta.

Allow Siri to control my Philips Hue lights via my Mac. Also hurry up and come out with a device to compete with Amazon Alexa and Google Home
