Apple is now on its ninth round of milestone operating system betas, but proceeding in a more restrained fashion, providing developers with access just to the ninth build of watchOS 6.
The latest builds can be downloaded by developers in the beta-testing scheme via the Apple Developer Center, or as an over-the-air update for hardware already using earlier beta builds. A public beta version of the releases is expected to start arriving soon, and will be available through the Apple Beta Software Program website.
The end of August is a late stage in Apple's development and testing of major operating system releases arriving this fall alongside new iPhone models, with beta builds offered at an accelerated rate. The eighth builds were provided on August 21, while the seventh were on August 15, and the sixth on August 7.
Betas of iOS 13, iPadOS 13, tvOS 13, and macOS 10.15 are yet to be issued in this round.
Both AppleInsider and Apple itself strongly recommend users don't install the betas on to "mission-critical" or primary devices, as there is the remote possibility of data loss or other issues. Instead, testers should install betas onto secondary or non-essential devices, and to make sure there are sufficient backups of important data before updating.
