    There is this huge thread on installing macOS Big Sur.
    I could install it on a new VM, so this thread here is focused on post Big Sur installation issues.

    In this case Big Sur runs fine (fresh VM, fresh Big Sur installation via DMG) until I install Parallels Tools via Actions / Reinstall Parallels Tools.

    After the reinstallation of Parallels Tools and after all permissions are granted via System Preferences / Privacy the VM gets stuck in a black screen after the reboot. Multiple reboots will not fix the issue.

    Workaround: restore a snapshot taken before the installation of Parallels Tools.

    Parallels Pro Version 15.1.4 (47270)

    Hello @backslash-f At the moment Parallels Desktop compatibility with macOS Big Sur hasn't been tested yet as it has been just released. As many other software vendors, Parallels Engineering team is looking to make the required tweaks to make sure you can run your virtual machines on macOS Big Sur, as well as install it in a virtual machine. Since the beta version of macOS Big Sur has just been released, the compatibility of Parallels Desktop and macOS Big Sur hasn't been fully tested yet by the Parallels Engineering Team.

    At this time, we do not have the exact ETA when Parallels Desktop will fully and officially support the newly released macOS. However, we are working hard to make sure macOS Big Sur works with Parallels Desktop for Mac.

    Feel free to share your feedback with us on Parallels Forum dedicated thread ( https://forum.parallels.com/threads/macos-10-16-big-sur-and-parallels-desktop.350219/ ) if you encounter any compatibility issues between Parallels Desktop and newly released macOS Big Sur installed on a Mac or used as a virtual machine.

    If your feedback includes technical data (http://kb.parallels.com/en/9058) along with a description of the encountered issue it will make further troubleshooting and resolution more efficient.

    Stay tuned for more updates on official support for macOS Big Sur.
