Mac Studio M3 Ultra (MacOs Tahoe 26.7)
Parallels 27.0.1
I install a brand new MacOS VM using Parallels (it only offers 26.6.2) using default settings in Parallel for the VM. It works, I can login etc. Then I go to settings in the VM to download the actual latest Tahoe version 26.7 (like the host machine), and it starts the process, even shows the black screen with the apple logo with a progress bar etc, but then just gets stuck on an empty black screen with nothing in it, and nothing happens for hours. I then reboot, and its still on 26.6.2.
