The second developer beta of tvOS 9.2.1 – Build 13Y763c – is available for download from the Apple Developer Center. Doing an initial installation of the tvOS 9.2.1 beta requires the unit to be connected to a computer with a USB-C toUSB-A cable, and the software needs to be downloaded and installed via iTunes or Apple Configurator.
Users can also set their Apple TV up for over-the-air downloads of the beta by downloading the Configuration Profile for over-the-air updates through Apple Configurator. Both files are available via the Apple Developer portal.
It isn’t clear what exactly either beta holds as far as new features and such, but both are likely the usual bug fixes and performance enhancements. We’ll let you know in the area below if we find anything else out about the new beta.
