Apple today began rolling out the first beta of tvOS 12.4 for testing on the most recent versions of the Apple TV. This comes after tvOS 12.3 was released for all users of the device. 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.
