Apple has released release candidate versions of its upcoming watchOS 26.4, tvOS 26.4, and visionOS 26.4 software updates, signaling the final stage of testing before public release. These updates bring a mix of new features and refinements to Apple’s operating systems for Apple Watch, Apple TV, and Apple Vision Pro, respectively. Release candidates are typically the last versions distributed to developers and public beta testers before a wider rollout, assuming no critical bugs are discovered in the meantime.
The arrival of these release candidates comes a week after Apple seeded the fourth beta versions of each operating system, indicating a swift pace toward final release. While tvOS 26.4 and watchOS 26.4 are available to both public beta testers and developers, access to visionOS 26.4 remains limited to developers, reflecting the relatively new nature of Apple’s spatial computing platform.
New Sleep Tracking Features in watchOS 26.4
For Apple Watch users, watchOS 26.4 introduces a new “Average Bedtime” metric within the sleep features. This addition, first highlighted in February, aims to provide users with a clearer understanding of how their bedtime consistency impacts overall sleep quality. The metric syncs with the Health app, allowing for a more comprehensive view of sleep patterns and potential areas for improvement. Understanding sleep patterns is increasingly important, and Apple continues to refine its health tracking capabilities with each software iteration.
Apple TV Gets a Streamlined Experience with tvOS 26.4
tvOS 26.4 focuses on streamlining the Apple TV experience by finally removing the long-deprecated iTunes Movies and iTunes TV Shows apps. As MacRumors reported, these apps have been non-functional for some time, with users directed to the Apple TV app for purchases. The removal represents a final step in consolidating Apple’s video services. Alongside this change, tvOS 26.4 introduces a Continuous Audio Connection option for HDMI output, potentially improving audio performance and connectivity for users with advanced home theater setups.
Foveated Streaming Enhances Vision Pro Performance
The visionOS 26.4 update brings a significant performance enhancement to the Apple Vision Pro with the introduction of support for foveated streaming. This technology streams video at full resolution only to the precise area where the user is looking, while compressing peripheral areas. According to Wikipedia, visionOS is built on iPadOS and utilizes frameworks for advanced rendering techniques like foveated streaming. This approach allows for higher visual quality and lower latency, crucial for immersive spatial computing experiences. Foveated streaming is a key technology for making graphically demanding applications and games run smoothly on the Vision Pro’s hardware.
The release of these updates underscores Apple’s commitment to continuously improving its software ecosystem. While the exact timing of the public releases remains unconfirmed, the arrival of release candidates suggests a launch is imminent. Users enrolled in the public beta programs will likely receive the final versions first, followed by a wider rollout to all compatible devices. Apple’s coordinated updates across watchOS, tvOS, and visionOS demonstrate the interconnectedness of its hardware and software strategy.
For those interested in participating in Apple’s beta programs, information can be found on the Apple visionOS website and through the Apple Beta Software Program. Developers can find resources and documentation on the Apple Developer website.
Apple’s next major software reveal is expected at its annual Worldwide Developers Conference (WWDC), where the company typically unveils the next generation of its operating systems. Until then, these updates provide incremental improvements and refinements to the current user experience.
