I installed the Big Sur Beta this afternoon on an iMac Pro. When I try to run Windows 10 or KDE Linux guest via Parallel's Desktop, I am unable to log in because not all keys are working. I thought it must have been a keyboard dust issue at first since it was so selective about keys, but those same keys work fine in Big Sur as a host. Most keys are working though.
I have tried to solve this by allowing Parallel's Desktop in Privacy and re-installing Parallel's Desktop.
Anyone else experiencing similar issues?
