Apple on Wednesday released tvOS 16.1.1, a rare standalone update for the third-generation Apple TV 4K that fixes a specific storage bug that affected the 128GB model.
It is not likely that the bug will affect many users, as it will only be noticeable when half of the storage space (approximately 64 GB) is full. At that point, the system prevents users from installing apps despite the available storage space. The update does not seem to have any other improvements. If you’re already on the tvOS 16.2 beta, it’s not clear if the latest beta also fixes the issue, but it should be fixed when it’s released later this year.
To update your Apple TV 4K, go to the Settings app System > Software updates > Update software and follow the directions.
