Apple Seeds Third Betas of watchOS 26.5, tvOS 26.5, and visionOS 26.5 [Download]

Apple has seeded the third developer betas of watchOS 26.5, tvOS 26.5, and visionOS 26.5 for testing.



The new test builds arrive alongside the third beta of iOS 26.5. The build numbers for today's releases are 23T5558e for watchOS, 23L5460d for tvOS, and 23O5458e for visionOS. They drop exactly one week after Apple provided developers with the second round of test builds.


This beta cycle appears primarily focused on under-the-hood performance improvements and stability patches following the public rollout of version 26.4 late last month. Apple has not published detailed release notes outlining specific new user-facing features for these platforms. Later beta stages typically concentrate on resolving bugs discovered during initial testing rather than introducing major interface changes.

Registered developers can download the updates by navigating to the Software Update section in Settings on their respective devices. The watchOS update must be initiated through the Watch app on a paired iPhone.
