Apple Seeds macOS Sierra 10.12.3 Beta 3 to Developers

Apple on Monday seeded the third beta of macOS Sierra 10.12.3 to developers. The third beta comes three weeks after the release of the second beta version of Apple's upcoming Mac operating system.

The first beta of macOS Sierra 10.12.3 – build 16D25a – is available for download via the Apple Developer Center or via the “Update” tab in the Mac App Store. 

Apple’s official release notes merely say the new beta “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.

Certainly, it won’t be long now until Apple takes the final step and releases macOS Sierra 10.12.3 to the general public. This specific version has been in testing for coming up to a month, and given the relatively small nature of the improvements, it’s likely that a public release is right around the horizon.

As always, the latest macOS Sierra 10.12.3 beta is now live to download and install immediately from the Mac App Store to those who are currently running a previous pre-release seed of macOS 10.12.3.
