Apple rolls out fifth developer betas for watchOS 9.6 & tvOS 16.6

Apple Watch Ultra

Developers in the beta program can access the newest versions via Apple Developer Center or update their device in Settings. Public beta participants can usually get the latest versions soon after the developer releases them through the Apple Beta Software Program.

The fifth beta iteration of watchOS 9.6 is identified by build number 20U5570a, replacing the earlier build 20U5559c from the initial release of watchOS 9.6 beta.

As for tvOS 16.6 and HomePod software, the new build number is 20M5571a, which supplants the previous build 20M5559c.

After launching the third betas for watchOS 9.6 and tvOS 16.6 on June 15, Apple introduced the fourth developer betas for both operating systems on June 27.

At this time, there is no detailed information about the features and changes included in the latest betas. However, as developers explore the operating systems, more information will become available.

AppleInsider and Apple strongly suggest users don't install beta operating systems or other beta software on "mission-critical" or primary devices, as there is the small chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware and ensure they have sufficient backups of their critical data at all times.
