Did I miss something about the latest update? I haven't upgraded to macOS Catalina because of the lack of backward compatibility, but I was expecting that this would not be an obstacle to upgrading to the last PD version. Maybe I missed a warning to this effect in the long list of changes posted on the information page? In any case, after I left my MBP to perform the PD 15.x.x update (shutting down my Window 7 VM first), I found an unresponsive Mac on my return. Shutting it down with the power button, doing a disk repair and restarting seemed to restore the well-being of my Mac, but as soon as I tried to start my VM, the dreaded beachball reappeared. I am currently repairing my external disk after I had to shutdown my Mac with the power button, and wonder what could be my next move once this is done? Do the same again (probably to the same effect)? Try a backup VM? Downgrade (if that is even possible)? Thanks for any feedback.
