macOS Sierra 10.12.3 Beta 4 Download Out for Developers

Developers, time to wake up—macOS Sierra 10.12.3 beta 4, build 16D30a, is now available for download. The release comes four days after the release of beta 3, and should come with the usual bug fixes and performance improvements.

No word on any major features in this build, but stay tuned for updates. It does include a fix for new MacBook Pro models, as a bug caused battery life tests from Consumer Reports to vary widely.
