Apple Seeds First Beta of macOS Sierra 10.12.3 to Developers

Apple today seeded the first beta of an upcoming macOS Sierra 10.12.3 update to developers, just one day after releasing macOS Sierra 10.12.2 and almost three months after launching the macOS Sierra operating system.

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.

Because this is a first beta, we don't yet know what features are included in the update, but Apple's release notes say the 10.12.3 update "improves the stability, compatibility, and security of your Mac." We'll update this post with any changes that are discovered in the beta.

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.

A "crying baby" emoji could come in real handy here.

What a year. I'm in no rush to upgrade, if you can call it that, to Sierra. Usually I upgrade at the .2 release. Sierra has been underwhelming. I've never skipped an OS but may do it this year. 10.11.6 is working great and I don't need the new emojis in messages. I don't trust iCloud syncing. Am I missing something?
