Apple today seeded the fourth beta of tvOS 27 to developers for testing, arriving two weeks after the third beta. The update can be downloaded via the Settings app on Apple TV with a free developer account. tvOS 27 brings few new features but focuses on stability improvements and bug fixes for the streaming platform.
Stability and performance enhancements for Apple TV
With tvOS 27 beta 4, Apple addresses multiple issues reported by testers. Key fixes include better memory management, improved HDR10+ playback, and more reliable HomeKit connectivity. AirPods synchronization has also been optimized. Users relying on Apple TV as a smart home hub will notice fewer glitches when using Siri voice commands.

Small refinements instead of a major redesign
tvOS 27 does not overhaul the user interface. Instead, Apple eliminated minor annoyances such as app launch delays and Siri Remote battery drain. Developers report snappier menu navigation and smoother screen transitions. No major new capabilities have been introduced, indicating a focus on polishing the existing experience.
Comparison with other beta releases
Apple also released beta 4 of iPadOS 27, visionOS 27, and more today. This synchronized approach allows developers to test across the ecosystem. Those tracking macOS can compare the pace with the macOS Golden Gate beta 4 release.
