The tvOS 10.1 update can be downloaded on the fourth-generation Apple TV using the Settings app. Go to System --> Software Update to install. For those who have automatic software updates turned on, the Apple TV will be upgraded to tvOS 10.1 automatically.
Apple has also released an 8.4.2 update for third-generation Apple TV owners, which is available alongside tvOS 10.1.
tvOS 10.1 introduces a brand new "TV" app, which is designed to make it easier for users to discover new content across the dozens of television and movie apps that are available.
It serves as a sort of Apple-designed television guide, giving customers a way to find and watch TV and movies across multiple devices. It features a dedicated store, recommended content, and cross-device syncing.
The TV app works hand-in-hand with Single Sign-On, a long-promised tvOS 10 feature that was introduced last week. Single Sign-On lets users sign in with their cable credentials one time to access all live cable content they're entitled to across multiple apps.
Single Sign-On is currently available for CenturyLink Prism, DirecTV, Dish, GVTC, GTA, Hawaiian Telcom, Hotwire, Metrocast, Service Electric, and Sling TV.
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.
