Apple pushed out iOS 26.2.1 on January 26, 2026, and the company has now seeded tvOS 26.3 beta 3 to developers as the next step in the 26.3 testing cycle.
This update lands a couple of weeks after tvOS 26.3 beta 2 (23K5600b), which Apple listed on its developer releases page on January 12.
Apple has not announced a public release date for tvOS 26.3. Still, the beta schedule suggests the public update is not far off.
How to update tvOS 26.3 beta 3
- On your Apple TV, open Settings.
- Go to System.
- Select Software Updates.
- Choose Update Software.
- If you already run the developer beta track, install tvOS 26.3 beta 3 when it appears.
Note: You need an Apple ID enrolled in the developer beta flow on the device to see developer builds in Software Update.
Changes in tvOS 26.3 beta 3
Early installs have not surfaced any headline features yet, and Apple has not highlighted a specific change list for this beta.
Here is what you should expect right now:
- Bug fixes and stability work for Apple TV system apps and playback
- Performance tuning in the background, typical for late-cycle betas
- Under the hood changes that developers need to validate, even when the UI looks the same
What’s next: 26.4 betas and the Gemini-powered Siri talk
The next big thread is not tvOS itself, but what Apple plans to show during the next wave of platform betas. Reporting points to iOS 26.4 entering beta in February, with Apple preparing demos of a Gemini-powered Siri in the second half of February.
Final thoughts
If you install tvOS 26.3 beta 3, keep an eye out for small behavior changes around streaming, audio sync, and AirPlay. If you spot anything new, share it in the comments so other testers can verify it too.
