I managed to get my C6 working again. Go to finder and press: ‘shift’ + ‘cmd’ + g this will bring up a window asking you to go to a folder. Type ‘~/Library/Preferences/’ and press Enter. From in there (your user preferences folder) move ‘se.elektron.c6.plist’ to the trash.
That should do it - though it’s very easy to break it again.
