Apple today seeded the first beta of an upcoming tvOS 12.1.1 update to developers for testing purposes, one day after releasing tvOS 12.1, the second update to the tvOS 12 operating system designed for the fourth and fifth-generation Apple TV models.
The new tvOS 12.1.1 developer beta can be downloaded onto the Apple TV via a profile that's installed using Xcode.
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. Should anything new be found, we'll update this post.
