Following the release of iOS 15.5 and macOS Monterey 12.4 to all users, Apple on Monday also made tvOS 15.5, watchOS 8.6, and HomePod Software 15.5 available to the public. The updates bring overall improvements with no major changes.
Apple doesn’t specify what has changed with tvOS 15.5, so we assume that the update just fixes some bugs and improves the performance of the operating system for Apple TV users.
The update is now available for Apple TV HD (4th generation) and later users. You can install the latest version of tvOS by going to Settings > System > Software Update.
