Yay! We can now sign in to VMs with iCloud... but still can't get in-place beta updates inside a VM :(
My use case not covered. Enormously frustrating (this is the polite way of putting it). Especially since the older way of combatting this by doing defaults write to com.apple.MobileAsset to set the asset audience and URL manually also no longer seems to work.
It seems Apple really demands me to have to spend over an hour for each beta drop to re-initialize my automation environments for integration testing.
:(
