I'm having a similar problem but I'm running a Mac OS X guest on an Ubuntu 21.10 host.

a Mac guest is only allowed if the physical computer is real Mac hardware.
OSX guests on non-Apple hardware

If you really do have a Mac computer, please start a new topic in the Mac Guests subform, with a zipped guest vbox.log, posted using the forum's Upload Attachment tab.
