Take tvOS 27 Beta for a Spin on Your Apple TV and Test Out the New Features, Download it Today

Unless you’re actually a developer, I don’t see any reason why you would want to test out a tvOS beta on your Apple TV. But, there are plenty of fans out there that actually do this sort of thing, and I bet you’re one of them.

If you’ve tested out tvOS betas in the past, then you already know what needs to be done. But if you’re doing this for the first time, then it all starts with signing up to the Apple Developer Program.

Enable tvOS 27 Beta Updates on Apple TV

Once you’ve signed up to the Developer Program, you then have to enable tvOS developer beta updates on your Apple TV. Just follow these steps and you’ll be up and running in no time:

Step 1. Turn on your Apple TV.

Step 2. Launch the Settings app.

Step 3. Now open System.

Step 4. Open Software Updates.

Step 5. Open Get Beta Updates and select tvOS 27 Developer Beta.

Download tvOS 27 Developer Beta

Now that you’re set to receive tvOS 27 beta updates, you can download it just like any other software update from Apple. Follow these steps:

Step 1. Launch the Settings app.

Step 2. Scroll down and open System.

Step 3. Open Software Updates.

Step 4. Now open Update Software.

Step 5. You will now see the tvOS 27 developer beta update. You can install it immediately, or delay it for some later time, entirely up to you.

If you have decided to install the tvOS 27 beta, then do keep in mind that your Apple TV will restart several times. You will see a completely black screen for a while, so make sure you do not turn off your TV or do something on the Siri Remote. Once the installation is complete, you’ll boot straight into tvOS 27 beta.

Since you’re dealing with a beta, therefore expect things to be slightly broken. This means failed security camera backups, or accessing your smart home from far away may become a problem, if your Apple TV is being used as an Apple Home hub.
