macOS Sierra 10.12 Beta 7 Available for Testing
Apple has released the seventh beta version of macOS Sierra to users participating in the Mac developer beta testing program. The same build is also available to public beta release testers versioned as macOS Sierra public beta 6.
Mac users running a prior version of macOS Sierra 10.12 can find the latest version available now from the software update mechanism of the Mac App Store.
Anyone can choose to download and install macOS Sierra public beta but given the nature of beta system software, it is generally only recommended for more advanced users, and to test on a non-primary machine. Another option is to dual boot macOS Sierra with a stable Mac OS X release like El Capitan, but again, that is appropriate for advanced Mac users only.
Apple usually releases beta updates concurrently but for this release they have been staggered. For the iPhone and iPad, iOS 10 beta 7 and public beta 6 was released last week. A new beta build for watchOS 3 and tvOS 10 have not yet been released.
The final version of macOS Sierra will be available sometime this fall, though an exact release date is not yet known.
