Apple Seeds Second Beta of macOS Sierra 10.12.3 to Developers

Apple today seeded the second beta of an upcoming macOS Sierra 10.12.3 update to developers, one week after seeding the first 10.12.3 beta (http://www.macrumors.com/2016/12/14/apple-seeds-macos-sierra-10-12-3-beta-1/) and a week after releasing macOS Sierra 10.12.2 (http://www.macrumors.com/2016/12/13/apple-releases-macos-sierra-10-12-2/), the second update to the macOS Sierra operating system (http://www.macrumors.com/2016/09/20/macos-sierra-released/).





The second macOS Sierra 10.12.3 is available for download through the Apple Developer Center or through the software update mechanism in the Mac App Store (http://www.macrumors.com/roundup/mac-app-store/).

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 beta, but we'll update this post should any new features be found in the second beta.





Oftentimes, with bug fixes, it's difficult to tell just what's included until Apple supplies detailed release notes with a release. The previous update, macOS 10.12.2, introduced several important bug fixes (http://www.macrumors.com/2016/12/13/apple-releases-macos-sierra-10-12-2/) to resolve battery life issues, fix graphics problems, and more.





Available since September, macOS Sierra is the latest Mac operating system. It includes Siri (http://www.macrumors.com/roundup/siri/) support, Apple Pay (http://www.macrumors.com/roundup/apple-pay/) for the web, Universal Clipboard, Apple Watch auto unlocking, improved [url=http://www.macrumors.com/roundup/icloud/]iCloud (http://www.macrumors.com/roundup/icloud-drive/) Drive[/url] integration, Picture-in-Picture multitasking, and dozens of smaller features that can be found in our macOS Sierra roundup (http://www.macrumors.com/roundup/macos-sierra/).
