    Please post your tech report ID at this thread.
    We also would like to inform you, that we've involved Parallels Engineering team in this case, but more technical information will be very helpful.
    Looking forward to your reply.

    Do you have any updates to share regarding support for running Mac OS Big Sur (Guest) on Mac OS Catalina (Host)? Ping @Maria@Parallels.

    I installed Ben Sur beta 9 in Parallels 16.0.1 on a Catalina host, and all I get is a black screen after it reboots. Is there a version of the beta that does work? The knowledge base article implies that it should work.

    Hello, did you try to reset your VM?

    Yes I did and it did the same - just a black screen. I just did the upgrade from Catalina again and it worked. This time I started from 10.15.7 (previously 10.15.5 I think), and had 128Gb disk space instead of 100Gb, and it worked.

    Dear Maria,

    There is no error, it's just when you go and click on top right corner to select a USB device such as flash drive, external drive, usb camera or USB wireless adapter nothing happen.

    Thanks

    Please sorry for the inconvenience, but could you please share a bit more details? Are you unable to connect it to Windows VM?

    I connect usb, it appears from above in parallels, I click on it but nothing happens. The checkbox is not checked, but it does not give an error either. I have the same situation as the user described above
