Apple today seeded the fourth betas of watchOS 26.4, tvOS 26.4, and visionOS 26.4 to developers for testing. The updates arrive a week after the third beta releases and are available through device Settings for those with free developer accounts.

The watchOS 26.4 beta adds an Average Bedtime metric to sleep tracking, syncing with the Health app to help users understand how bedtime affects sleep quality. tvOS 26.4 finally removes the long-defunct iTunes Movies and iTunes TV Shows apps from Apple TV, which have been redirecting users to the Apple TV app for purchases anyway. The update also introduces a Continuous Audio Connection option for HDMI output.

visionOS 26.4 brings foveated streaming support for apps and games, a technology that streams video to where users are looking while compressing peripheral areas. This delivers higher visual quality and lower latency for Apple Vision Pro users. The foveated streaming feature represents a significant enhancement for immersive experiences on the spatial computing platform.
