    On Parallels Desktop 16 Business Edition, I installed 10.15.6 an a Guest OS and tried to upgrade to Big Sur 11.0 beta8.
    successfully downloaded installer app, but while installing, it stuck in black screen, it keeps continuing....
    Paralles is the most recent version 16.0.1 , but it still happens... How can I upgrade Catalina to Big Sur?
