macOS Big Sur and Parallels Desktop

I have the Network and USB issues too. And it doesn't show any specific error message for USB, the drive simply disappears from Mac OS as if it was connecting to the VM (and it is in fact shown as connected in the Parallels topbar menu) but the VM doesn't acknowledge it. No message, nothing simply happens.

Hi, please collect the tech report once the issue reproduced and post the report's ID here?
 
2019 MBP 16". I had many graphics related problems with PD 16 on Catalina, so I reluctantly upgraded to Big Sur to see if it would be fixed. However, the problem is the same. When running my CAD software (Altium Designer) there is screen tearing and graphical glitches. This is able to bring down the entire Host MacOS and crash the whole system. I have tried reinstalling Parallels Tools, changing all available Graphics options, disabling automatic graphics switching, changing hypervisors, etc. Nothing helps.

Re: graphics related crashes above. It seems when I do not use my external Thunderbolt monitor, the glitches and crashes do not occur. I hope this clue can help you solve the problem.
 
Are there any suggestions for how to avoid crashes with an external monitor in PD16? I sent several technical reports during the crashes last week, but my system became unusable while sending the report so I don't have the report numbers. Are you able to look them?

Hello, it looks like a known issue, but without a tech report we will not be able to fund the root cause of the issue.
We checked your email address and didn't find and report associated with it,
May we ask you for new tech report (collected right after the issue reproduced) and reply us back with the report's ID?
 
Hi, I've been moving from High Sierra, and I'm evaluating Big Sur (Beta)(Sorry for the beta software because I'm on MBR mid-2014 and real Big Sur has an ongoing widespread problem with my machine [1]. So I avoid it for now.) for more than two months now. I've found that Graphics rendering on Coherence Mode on Big Sur is stuttering. This is Windows 7 x64 as the guest OS. I've tested on High Sierra already, and this problem only exhibits on Big Sur. This problem makes scrolling documents, choosing item in popup menu, moving window or any any animation feels sluggish. While the stuttering is a pain but somewhat tolerable annoyance for scaled resolution, it is severe for retina resolution. This problem exhibits on all Big Sur Beta 6,7,8,9. I've the lastest Parallels 16.1.1 (49141). Does anyone with any other MacBook model or full Big Sur version also have this problem is currently beyond me.

Running Microsoft EDGE causes PD 16.1 to crash to desktop on many websites (or trying to export bookmarks), CPU increases to 75-100% (fans fire up).

SSD Drive (SamSung T5/500gb) will not connect to guest (says its 'busy' -- its not, and TimeMachine partition is ejected prior).

Host/Guest: 11.0.1 (public) and 11.1RC2 tested, same result on either.

Has anyone also experience the stuttering?
 
After repairing the network and USB implemented in two XML PD16 files - provided by our forum member *** RenatN *** - we can run our virtual machine, but unfortunately we cannot use devices other than USB flash drives. We can't mount anything like USB port emulation or other USB stuff in VM PD16. It would be nice to see Parallels TECH involved in this little thing, especially since virtualbox has no problem with it.

@for ALL who needs USB to COM Port emulation, drivers, mount in VM etc please vote here:

Big Sur not asking where to use peripherals after parallels 16 installed - card reader must be used on windows, bt being initialized automatically on Big Sur. Before I got a popup asking if I wanted to use it on OS or Parallels. ANYONE? thanks a lot
