Apple on Monday released tvOS 15.5, the fourth major update to the latest tvOS operating system that launched in September 2021. tvOS 15.4 is compatible with the Apple TV 4K (1st and 2nd generation ) and the Apple TV HD.
The tvOS 15.4 update is free and can be downloaded via the Settings app on the Apple TV by going to “System” -> “Software Update.” If you have automatic software updates turned on your Apple TV will be upgraded to tvOS 15.4 automatically.
We don’t have any information on what’s included in the new update, 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.
Apple does not provide detailed release notes for its tvOS updates, but the company does offer some tvOS information through the tvOS support document.
