I'm trying to enroll 20 AppleTVs via Configurator. I've called Apple support 3 times on the issue, each time the phone call lasts over an hour and I have to end the call to do other things. Still no resolution. Here's the scenario:
When you plug the AppleTV into Configurator, it pops up a setup assistant. You select Enroll > Casper MDM from the first screen, then it will prompt you for the device name and other profiles you want to install. Then you click Next again and it will wipe the AppleTV, install the latest software and reboot your ATV. As it's walking through the final configurations after reboot, it gets to the step "Updating device properties." It sits there for about 30 seconds and then errors out. The error is:
Unable to update device properties
Error details: The operation timed out. Code: -402653172 Domain: com.apple.mdk.amderror
If I skip Enroll (and therefore cannot set a name nor a WiFi profile, thus removing 90% of the reasons to put an AppleTV in configurator in the first place), then it rolls through 'Update device properties' just fine without any hiccups.
