Apple TV will soon be getting a big software update soon — tvOS 15 — which was unveiled at WWDC recently. Like other Apple devices’ new software, you can test out the new features of tvOS 15 early if you are part of Apple’s public beta program.
Warning: If you install the tvOS 15 on a newer Apple TV 4K box then you won’t be able to roll back to tvOS 14 as you cannot connect the latest Apple TV 4K box with a USB-C cable to your computer.
Devices that support tvOS 15:
Apple TV 4K(2021)
Apple TV 4K(2017)
Apple TV HD
Here is how to install tvOS 15 on your Apple TV:
Open https://beta.apple.com/sp/betaprogram/ and sign up for the Apple Beta Software Program on your computer.
Go to the tvOS tab after you are signed in.
Click on “Get Started” and enroll your Apple TV.
Open the settings menu on your Apple Tv and click on “Users and Accounts”.
Make sure that you are using the same Apple ID on your Apple Tv which you used to sign up for the beta program.
Select “System” > “Software Update” > toggle on “Get Public Beta Updates”.
Update your Apple TV from your system settings after you have enabled the Public Beta Update setting.
