Two weeks after the third build hit airwaves, Apple has begun rolling out the third tvOS 12.4 beta for testing on the Apple TV. The beta should become available for both developers and public testers this week.
The new software can be installed by going to the Software Update section of the Settings app and hitting the download button. You’ll have to be registered as a developer or public beta tester to try out the new OS, however.
tvOS 12.4 will likely include bug fixes, security improvements, and other under-the-hood enhancements. It’s unclear if any user-facing changes have been made, but we’ll let you know if any are spotted.
