Apple on Thursday seeded the release candidate of tvOS 15.5 to developers for testing. The new RC comes one week after the fourth beta seed of the Apple TV operating system.
The tvOS 15.5 RC is with the Apple TV 4K (1st and 2nd generation) and the Apple TV HD. The new beta can be downloaded to a compatible Apple TV that has the proper profile installed, which can be done by downloading it onto the Apple TV using Xcode.
We don’t have any information on what’s included in the RC, but other than the usual annual OS revisions, tvOS updates generally focus on under-the-hood bug fixes and improvements rather than major outward-facing changes.
As usual, MacTrast and Apple both warn users to not install any betas (or release candidates) on their daily driver Apple TV, especially early betas of new operating systems. Instead, only install betas on a device set aside for testing purposes.
