How to install the tvOS 16 public beta on your Apple TV

Apple is rolling out the first public beta of tvOS 16. That means public beta testers, or any non-developer, can download and try the new update on their Apple TV (the newer models, anyway).

To get the beta version of Apple's next operating system update running on your set-top box, you need to sign up for Apple's beta testing program. It's free to join. Then, you need to install the proper certificate from Apple's public beta website, and then you can grab the updates over the air. 

If you've joined Apple's free beta program previously, you'll need to enroll again for these latest versions. Here's everything you need to know.
