It’s funny, Parallels 16 runs everything I’ve thrown at it... despite running on a 2008 MacPro. That includes leading-edge Linux variants, numerous MacOS versions (10.9 through 10.15), Windows (XP through Win10), and even some obscure OSs from BellLabs and others.
The only snafu I’ve hit, involves BigSur: While the MacOS installer starts up, the keyboard and mouse don’t work. Thus far, only two of us have brought it up in the Parallels forums, so perhaps it’s rare: <>
Glad to hear it’s working for you, Ken! Hopefully the Parallels folks will fix this issue soon...
