Apple today provided developers with the fourth beta of tvOS 10, the next-generation operating system designed to run on the fourth-generation Apple TV. tvOS 10 beta 4 comes two weeks after the release of tvOS beta 3 and more than a month after the operating system was first shown off at Apple's 2016 Worldwide Developers Conference
tvOS betas are more difficult to install than beta updates for iOS and OS X. Installing the tvOS beta requires the Apple TV to be connected to a computer with a USB-C to USB-A cable, with the software downloaded and installed via iTunes or Apple Configurator. Once a beta profile has been installed on the device through iTunes, new beta releases will be available over the air.
tvOS 10 builds on the features initially introduced in tvOS last October, bringing expanded Siri capabilities with topic-based search, Live Tune-In for automatically accessing live channels, and options for managing HomeKit accessories.
Single-Sign On allows users to sign in and authenticate cable credentials just once instead of requiring authentication in all cable-supported apps, games are now able to require controllers, and there are new features for Photos and Music.
A dark mode offers a better visual experience for darker rooms, universal apps are automatically downloaded, and there's a new Apple TV remote for iOS devices that mirrors the Siri Remote.
