Apple has just seeded the third beta of tvOS 10.1 to developers for testing purposes, one week after seeding the second tvOS 10.1 beta and more than a month after launching tvOS 10.
After Apple seeded the first developer beta, the company officially rolled out the Single Sign-On feature, which allows iOS and tvOS users to sign in once with their credentials post which they will be automatically logged in to that service in any app. For now, the feature only supports a limited number of cable services, like Dish, Hotwire, GVTC Communications, and Sling TV, with other major cable TV providers like Comcast and DirecTV missing.
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.
To update, developers must have their Apple TV connected to their computer running iTunes via a USB Type-C to USB-A cable. The software can then be downloaded and installed to the Apple TV 4 running tvOS through iTunes or the Apple Configurator. Once that initial beta software has been installed, all subsequent seeds can be downloaded as over-the-air updates.
