Apple’s second developer betas of watchOS 10.4, tvOS 17.4, and macOS 14.4 are now available for testing.
Developers taking part in the beta program can get the latest versions from the Apple Developer Center or by updating their devices over the air with the beta software. Public beta releases generally appear shortly after the developer versions, and users can sign up via the Apple Beta Software Program.
The second watchOS 10.4 developer beta arrives after the first, which Apple brought out on January 29. The second watchOS 10.4 beta has build number 21T5196d, replacing the first one, build number 21T5185g.
