As per Notcom blog -
I’ve updated TU for apple tv 5.0.2 (sorry for the wait!) as well as all of the iOS 6 betas. I’ve had to change the way the OSX app is packaged. No more installer for now as Gatekeeper sucks more than taxes.
So now it is a simple zip but you will have to give your admin password at the first launch (it shouldn’t ask for it again after first launch).

1. Download TinyUmbrella and launch on your computer.
2. Connect your iOS device to your computer using USB cable. Let TinyUmbrella to detect your device.
