Apple today seeded the fourth beta of an upcoming tvOS 17.4 update to developers for testing purposes, with the beta coming one week after the release of the third tvOS 17.4 beta.


Registered developers are able to download the tvOS 17.4 update by opting in to the beta through the Settings app on the Apple TV. A registered developer account is required.

tvOS software releases are usually minor in scale compared to other operating system updates, focusing primarily on smaller improvements rather than outward-facing changes.

The tvOS 17.4 update adds support for Apple Music SharePlay on the Apple TV. The Apple TV user can pull up an Apple Music QR code that can be scanned by anyone, which then allows multiple people to contribute to what's playing via Apple Music. An Apple Music subscription is not required.

We've also seen references to homeOS in tvOS 17.4, but it's not yet clear what homeOS is.

tvOS 17.4 is expected to see a release in March alongside iOS 17.4.

Todays tvOS 17.4 beta 4 (21L5222a) - February 20, 2024 didn't reflect any more changes. No SDK notes to speak of. After the March 4th release, hopefully we see something new with tvOS 17.5 next beta cycle. Amazing that Apple TV HD is still being updated with the latest tvOS 17.x.

Does not fix the rampant HDMI issues with CEC + Multichannel Audio present since 17.2. Does not fix the constant output bit fluctuation present since tvOS 14.

Hmm. There seems to be a whole new Privacy Welcome screen after beta is installed. Including info on "Device Trust Score". Is this new for AppleTV or has it always been like that? Sorry if I've missed this in previous versions.

So long as they stick with this horrid new interface, who cares. They flat out ruined a perfectly beautiful and functional UI.
