Cannot install Extensions on macOS 10.15 (read-only Macintosh HD)
Each time a try to install either extension, "General HQ" and "Drumline," I receive a failed notice saying that it can't be installed on a read-only volume. I'm assuming this is a problem with the way macOS Catalina (10.15 —now 10.15.1) has updated permissions and has limited access to the system volume. Both extensions install fine on a machine that is still running 10.14, however, I don't want to roll back my current machine in order to do this.
I've given MuseScore full disk access by modifying the System Preferences > Privacy settings as directed in several other forum topics, but it has not solved the problem.
I'm wondering where MuseScore is attempting to install the files, AND if it's possible to change where those files are being installed OR if I can change the permission of the volume that it's trying to install to.
