macOS Sierra 10.12.6 beta 4 Download Available for Developers
While all the attention may be on macOS High Sierra, the predecessor of the latter has received a fourth beta today for developers.
Apple has released macOS Sierra 10.12.6 beta 4 (build 16G18a), and it is available for download now via the Mac App Store, for developers.
The release comes after beta 3 was released last week. No word on what’s new, but expect the usual bug fixes and performance improvements.
