Apple has kicked off the tvOS 26.4 beta cycle. The company seeded tvOS 26.4 beta 1 to developers on February 16, 2026, with build number 23L5208m.
This first beta lands just days after tvOS 26.3 rolled out to the public on February 11, 2026 (build 23K620).
As usual for an early point release beta, expect a mix of under-the-hood work and smaller tweaks that take a few installs to surface. If you are testing on your main Apple TV, remember that beta builds can introduce stability issues, app glitches, or unexpected behavior.
How to update to tvOS 26.4 beta 1
- On your Apple TV, open Settings.
- Go to System > Software Updates.
- Open Get Beta Updates and select the Developer Beta track.
- Go back and choose Update Software, then download and install.
Keep your Apple TV plugged in, stay on Wi Fi, and let it complete the restart before you start testing apps and streaming.
Changes in tvOS 26.4 beta 1
Right now, tvOS 26.4 beta 1 looks like a standard first seed where the biggest changes often sit in bug fixes, performance tuning, and framework adjustments that developers notice first.
That said, this beta cycle matters because it lines up with the broader 26.4 wave across Apple platforms, where attention has been building around Siri and Apple Intelligence progress. We will report again if we spot meaningful tvOS specific changes, including anything tied to Siri behavior, system intelligence features, or new user facing controls.
Let us know in the comments if tvOS 26.4 beta 1 fixes a bug you have been dealing with, or if it introduces a new one.
