Apple today seeded the third beta of tvOS 10.0.1 to developers for testing purposes, one week after releasing the second tvOS 10.0.1 beta and a month after releasing the tvOS 10 update. tvOS 10.0.1 has been in testing since September 21.
Designed for the fourth-generation Apple TV, the tvOS 10.0.1 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.
No obvious outward-facing features were discovered in the first two tvOS 10.0.1 betas, so it’s likely the update focuses on bug fixes and under-the-hood performance improvements to address issues discovered since the release of the first version of tvOS 10.
Single sign-on, a feature that will allow Apple TV users to sign in once with their cable credentials to access all live cable content included in a cable subscription, does not appear to be included in this beta and will be introduced in the future.
tvOS 10 brings improved search, expanded Siri capabilities, a new dark mode, a Continuity option for using the iPhone for text input, automatic download of universal apps, easy access to live TV, and more.
