Apple this week seeded the fifth beta of tvOS 15.4 to developers for testing. The new beta comes one week after the fourth beta release.
The tvOS 15.4 beta is with the Apple TV 4K (1st and 2nd generation) and the Apple TV HD. The new beta can be downloaded to a compatible Apple TV that has the proper profile installed, which can be done by downloading it onto the Apple TV using Xcode.
tvOS 15.4 brings support for captive Wi-Fi networks, allowing you to use your iPhone or iPad to connect your Apple TV to networks that require additional sign-in steps, like at hotels or dorms.
The beta also adds an “Up Next” queue directly to the video player for easier access. A new volume button is accessible from the video player.
As usual, MacTrast and Apple both warn users to not install any betas on their daily driver Apple TV, especially early betas of new operating systems. Instead, only install betas on a device set aside for testing purposes.
