macOS Big Sur and Parallels Desktop

According to https://arstechnica.com/gadgets/202...ds-big-sur-support-3d-metal-support-and-more/ PD 16 has now launched (and indeed, I see it for sale) with full support for Big Sur. The only thing keeping me from installing the beta of Big Sur has been the loss of my VMs due to the issue we've all seen and commented on here. Has anyone tried PD16 on Big Sur (as the host) and can comment?

 

I've installed Parallels Desktop 16 this morning. It's still completely broken. It will not start. Just keeps asking me to restart my Mac. Same as before.

 

I've also just tried deleting the Parallels Desktop app and then re-installing v16. Still the same result. Won't start, and just asks to restart the Mac.
What's the procedure for completely removing Parallels Desktop?

 

With PD15, Big Sur guest can install from installation media, but as soon as installing Parallels Tools, it won't boot.
After Installing the parallels tools in Big Sur guest on PD16, the VM boots (yay), but the graphics drivers are not working (still using default/fallback graphics, no integration). Are the parallels tools supposed to work with a Big Sur guest ? I don't see anything about this on the KB - should i raise a ticket?

 

same thing happens to me
please give us a full instruction of how to reinstall

 

Tried to completely uninstall parallels with app clean. Still hanging in the loop.

 

Here the same issue. Big Sur as host, Parallels always asking to restart the Mac. After the restart same thing again. Anyone with a successful installation on BigSur Beta 4 here?

 

Well, my MacBook Pro 15" is having constant crashing, mainly when Parallels 15 was running. However, now with Parallels 16 I can't even start the VM,

 

I had a bit of success,
- PD16
- I still had to enable the "allow extension" from security in preferences (but I didn't get a popup, just stumbled upon it)
- I then changed the hypervisor to "Parallels" as I was using Apple
I have noticed that the UI of settings jumps around as I'm selecting options, i.e. selecting parallels in hypervisor displays a screen over the top and then you can see parallels overlapped, but strange, but seems cosmetic.
So far seems to be working, but it was usually a couple of hours before my Mac would power off

 

Hey
I've installed PD16 on my Mac, and restarted when prompted. But now the VM just hangs during startup.
Version 16.0.0 (48916)
VM Win10, latest update.

Please assist ASAP.

 

Currently, on a support chat with an agent. PD16, macOS Big Sur Public Beta. It still doesn't work.
They got me to run a command in the terminal which they seemed pretty sure was going to fix the problem following a restart.

sudo kextcache --clear-staging

But it didn't fix the problem. Now they are taking technical data so it would seem they are not sure why it's still broken.

 

It seems PD16 is not so ready for Big Sur LOL

 

I just got off the support chat. No solution, unfortunately. They need to investigate further with the technical data I provided. They said someone will follow up with me via email.

As I said previously though, the VMware Tech Preview does run on Big Sur. I have my VM up and running in that on Windows Insider build 20185. But it's not ideal. It feels buggy and sluggish. But maybe acceptable to some people I guess.

Again, thank god for Bootcamp.

 

Has anyone got PD16 successfully running on Big Sur Public Beta? I would be interested to know if the problem is widespread or specific to me?
I can understand why Parallels would release v16 claiming full support for Big Sur when it's broken. They have released this early too I think because of the issues. Going from previous years, the update usually doesn't come until around the 20 August.

 

Well, I did get it to run now. I don't know if has anything todo with what I did or it just "fixed" itself.
I let it hanging for 30min. Tried "Actions -> Shut Down". Didn't work. Tried "Actions -> Stop". Didn't work. Now I forced it to quit. When I restarted the PD, I got the prompt to restart the Mac due of Parallels installation. I restarted the Mac, and fired up Parallels VM again. Same thing, same freezing screen. Let to hang like 30min again, and then I tired "Actions -> Reset". After 10min I forced to quit again and restarted the Mac once more. Now I entered the Configuration and had a look around. I changed the CPU & Memory, Hypervisor to Parallels. Now when I started the VM I got the message in the Windows login that it is trying to do a repair. It took like 5min and now I got the prompt and logged on the VM. When logged in, the Parallels Toolbox started to install. I was prompted to restart Windows. I did. When logged on Windows again, I shut it down so I could revert the CPU & Memory setting to Apple again. Started the VM/Win and all OK.
As I said, I don't know if it has anything to do with anything, but I'm up'n'running now.. 2,5h later..

 

I gave it a try too - to no avail. Only noteworthy issue: the dialog box that popped up after I reran, mntioning that Developer Tools Access has to take over:

 

My problem hasn't been resolved with Parallels 16. I still have to start in safe mode for the BS guest to be useable.
Please don't underestimate my issue: it's not because I'm the only one describing it here that I'm the only one encountering it.

 

Exactly the same here.

 

Hello, could you please collect the tech report once the issue reproduced please?
And share with us the report's ID.
(short issue description will be very helpful, it's a very long thread.)

 

Thanks for sharing all this information. Will wait a bit before upgrading to Big Sur.
