Apple on Friday seeded the first beta of tvOS 15.3 to developers for testing purposes. The beta came a few days after the release of tvOS 15.3 to the public.
The tvOS 15.3 beta 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.
As usual, MacTrast and Apple both warn users to not install any betas 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.
We don’t have any information on what’s included in the new beta, but other than the yearly OS revisions, tvOS updates generally focus on under-the-hood bug fixes and improvements rather than major outward-facing changes.
