Is there a functioniong OTA update from beta 1 to beta 2? My Apple TV running beta 1 has the configuration profile installed, but still does not see any update to beta 2 available.
Nevermind. Apparently I forgot to restart after I installed the configuration profile. Not sure how old you are, but it's funny if you can remember back to 2001 when OS X came out, how one of the great new features was that it could update a lot more without requiring a total reboot. Usually you just needed to log in and out and you could keep your system running for years. Since then, OS X / iOS / tvOS has gradually required reboots for pretty much everything.
