Apple Seeds tvOS 10 Golden Master to Developers
Apple today seeded the golden master (GM) version of tvOS 10 to developers. The golden master represents the final version of tvOS 10 that will be released to the public. Apple has not yet shared when tvOS 10 will officially launch, but iOS 10 and watchOS 3 are coming on September 13 and macOS Sierra is coming on September 20, so either of those dates is a possibility.
tvOS beta software is more difficult to install than iOS or macOS beta software. Installing the golden master version of tvOS 10 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 updates will be available over the air.
