Apple Seeds Third Beta of tvOS 12.1.1 to Developers [Update: Public Beta Available]

Apple today seeded the third beta of an upcoming tvOS 12.1.1 update to developers for testing purposes, one week after releasing the second tvOS 12.1.1 beta and two weeks after releasing tvOS 12.1.

The new tvOS 12.1.1 developer beta can be downloaded onto the Apple TV via a profile that's installed using Xcode. Subsequent betas can be downloaded over-the-air.

We're not yet sure what fixes and changes the tvOS 12.1.1 update might bring, but it's likely to focus on bugs that were not able to be addressed in the tvOS 12.1 update.

Apple provides little information on its tvOS software and tvOS updates have historically been minor in scale, so we may not know what's included in this update. Nothing new was discovered in the first two betas, but we'll update this post if any new features are found in the third beta.

Update: Apple has made a new public beta of tvOS 12.1.1 available to its public beta testers.

mkv container support wiuld be nice
Install infuse and stream SMB shares from your Mac. It’s actually insanely powerful. If you have an Apple TV 4K it’ll hardware decode x265 if not, it’ll natively hardware decode x264 that’s in MKV... with ease... I use it constantly.

Seems like everybody is on a holiday....;)

JK, but it seems like there's not a lot of interest in the AppleTv lately.
This year, there's probably not much more to add to ATV 4K since it now has 4K Dolby Vision, 4K HDR, Auto Frame Rate switching and now Dolby Atmos. There really isn't anything missing from it.

Maybe next years HDMI 2.1 will open a new upgrade - UI in 120 fps, instant switching between frame rates, SDR, HDR etc. Once disc is dead, maybe the film companies will offer Dolby True HD to Apple. Exciting times for ATV.

As an iTunes, Netflix, Amazon Prime and app streamer, it's pretty perfect.
