Band-in-a-Box for Mac supports Mac OS X 10.6 to 10.15, and does not yet support Big Sur. We do not recommend upgrading to Big Sur at this time as there are some issues for which we have no workaround - this includes crashes, graphical glitches, and the aforementioned Notation not working. There will be announcements and a build update when these compatibility issues are resolved, likely sometime in December.

Some people are getting along mostly ok on Big Sur though.
