The new CrossOver wrapper for Big Sur has finally arrived. It is available on the website now for download. I am waiting for the newsletters to go out to put the announcement on Facebook. You will need to do a complete uninstall including the old CrossOver wrapper before downloading and installing RM7 with the new wrapper. Directions are in the link below. The Mac menu version number for the CrossOver wrapper is 7.6.5. same as the current RM7 version number.
