    Just an update: this issue remains even after upgrading Parallels to version 16.

    I see the same behavior after installing v16 tools into a BigSur guest VM. I am running Catalina on the host.

    This problem was gone after i removed VirtualBox from Oracle from my system and rebooted. I was getting errors from "org.virtualbox.kext.VBoxDrv" when i was watching the log messages from kmutil and kernelmanagerd.

    Weeks ago, I had upgraded from a macOS Catalina host to macOS Big Sur Developer Beta 1, and Parallels Desktop 15 stopped working, asking to reboot in order to "complete the installation". Yes, the System Extensions preferences panel was granted.

    I was sad and later reverted to Catalina, since none of my Windows and Linux machines were even able to boot, not even the Parallels Control Center showed up.
    OK, I said, let's wait for an update from the Parallels team.

    When I saw the news this morning that Parallels Desktop 16 has full support for Big Sur, I decided to give it a go now. On Catalina, the Parallels Desktop 16 upgrade works fine.

    But after I upgraded to Big Sur (this time Developer Beta 4 20A5343i), I'm, yet again, stuck in the reboot prompt loop.
    I'm a translator, and my software only works on Windows. The promises were set too high, it seems. Humph.

    I now have PD16 running on macOS Big Sur, with some help from PD 2nd line Tech Support. For me at least, the problem was something to do with VirtualBox. Running the uninstall utility in the terminal fixed the problem. The terminal uninstaller utility comes with the installer package.

    Thanks for your information. Just resolved my problem
    For anyone suffering from "To complete Parallels Desktop setup, please restart your Mac." and if you have install VirtualBox, here is how I resolved the problem:
    1. download VirtualBox package from : OS X hosts
    2. run VirtualBox_Uninstall.tool from the down right corner
    3. start PD16, and good to go, no reboot required
    PS: don't delete VirutalBox app from Finder, that won't work

    Well time to get this to work with VirtualBox lol. I have 2 other apps that leverages VirtualBox on the backend. SIGH.

    I seem to be able to install v16. When I attempt to launch my VM (WIN 10) and am prompted to enter my license key, web site opens and states that license requires an upgrade ($49.99). The email I received yesterday from Parallels Inc. stated the upgrade was available to me for free. Which is it?

    I didn't have it installed but I ran it anyway. Still stuck in the "reboot" loop.

    Here's the deal. Upgrade from v15 of Parallels to v16 this morning. Downloaded the public beta of Big Sur and let Parallels create an .iso of it. (Host machine is a 2019 16" MBP with 16GB RAM and 512GB SSD i.e., base 16" model, running macOS Catalina 15.5.6). Installation of Big Sur as a VM took a while but completed successfully.
    Afterwards I installed Parallels Tools. No matter what I do I cannot get the Big Sur VM to enter full-screen mode. It stays at a resolution of 1024x720, or something like that. Anyone else see this?

    if I want to upgrade via dmg, there is only "parallels starts upgrade" but never finish the installation, any suggests?

    PD 16 s working fine for me running the macOS Big Sur public beta and a Windows 10 VM. I did the following ...

    1. Installed PD 16 in macOS Catalina first. Launched my Windows 10 VM and verified that it was working correctly.
    2. Upgraded macOS Catalina to macOS Big Sur. Launched my Windows 10 VM and verified that it was still working correctly.

    I should point out that given the initial issues I had running PD 15 on the macOS Big Sur beta on a different machine ... I elected not to try to upgrade to macOS Big Sur on my primary machine at all until PD 16 was released today. So I have not tried any of the various workarounds that have been mentioned in this thread which may or may not be a contributing factor to the issues people are experiencing.

    After installing Parallels 16 on BigSur Beta 4 I am receiving the following error when trying to start a docker-machine vm created with the parallels driver:
    Starting "docker"...

    Just to add another data point. With VirtualBox installed Parallels 16 on macOS Big Sur Beta would not start and would report that you needed to restart macOS to finish setup. Uninstall VirtualBox and Parallels starts OK. Reinstall VirtualBox and Parallels 16 starts requesting a restart to finish setup again. Uninstall VirtualBox and Parallels 16 starts successfully again. This would appear to point to a conflict between Parallels 16 and VirtualBox

    Honestly, that isn't right that we have to pay again because of a bug fix. I understand if it was for new functionality, but you can't say, "Our fix is you paying more money to upgrade." It should be an update instead. That's why many people are leaving for VMware. I was just about to upgrade to the pro edition as well...
