macOS Big Sur and Parallels Desktop

[Maria@Parallels]

Running Big Sur Public Beta 6 (Build 20A5364e) with Windows 10 as my Virtual Machine and I have this strange grey bar in the top right hand corner of my VM screen. I have attached a screenshot for a visual. Anyone else experiencing this or know what is going on here? or possibly a fix? Thank you!

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.

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?

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.

Thanks a lot for your reply.

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

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
