Designed for the fourth-generation Apple TV, the tvOS 10.1 beta can be obtained by connecting the Apple TV to a computer with a USB-C to USB-A cable, downloading and installing the software from a registered developer account via iTunes or Apple Configurator.
Once a beta profile has been installed on the device through iTunes, new beta updates will be available over the air.
It is not yet clear what new features or changes might be included in the tvOS 10.1 update, but many Apple TV owners are eagerly awaiting a new single sign-on feature that will allow Apple TV users to sign in once with their cable credentials to access live cable content included in a cable subscription.
Single sign-on was not introduced in the initial tvOS 10 release, and Apple has said it will come in a future update. We are also expecting to see the new "TV" app soon.
tvOS 10, for those unfamiliar with the operating system, brings features like improved search, expanded Siri capabilities, a dark mode, a Continuity option for using the iPhone for text input, automatic app downloads, quicker access to live TV, and more.
