Most of the time I find myself asking the question why something doesn't work when I had reasonable expectation that it would.
In this case I find my self asking why something worked when I had NO expectation that it would!
It is well known that Apple's virtual machine sample code does not support authentication with Apple services: iCloud, iTunes, Developer, etc. So it was a great surprise when I attempted to update Ventura beta 1 to beta 2...IT WORKED!
System Update was able to authenticate with the Developer Beta Seed program and determine that my VM was enrolled and the update was applied without any issue.
Can anyone tell me why this worked while other attempts to authenticate fail?
