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 and a week after releasing macOS Sierra 10.12.2, the second update to the macOS Sierra operating system.

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.

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 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.

Is it too much to ask for specifics on bugs fixed in software updates? People shouldn't be having to ask "Does this fix _________ on my _______?". The release notes should cite specific issues.

This vague "improves the stability, compatibility, and security" Apple puts on every update really doesn't cut it.

* HOW does it improve security?
* WHAT is changed to help compatibility?
* WHERE was stability improved?

It's like I'm back in elementary school English class.

Hopefully Apple engineers are hard at work fixing the Notes sync issues with 10.12.2, alongside their commitment to updating emoji's. I'm not going to hold my breath.

Now, now...you don't need to know what's in these updates. Remember, Apple's target demographic are 12 year old girls whose bedrooms are filled with unicorns and rainbows and can't be bothered to know HOW or WHY things work. As long as there's more useless crap available to text to their friends, that's all that matters to Tim & Co. /s (maybe)
