I’m aware that the downloads recommend 10.11 for Mac, but I had Score running well for a week on 10.13.6 until a score crash. Thereafter, the GUI messed up, with the main window in solid grey and I cannot edit the timeline. I guess this may be expected, but am wondering if there are various invisible files installed which might fix the problem if get rid of them. I’ve tried a complete deinstall (via AppZapper) and reinstalled, with same problem recurring. However, I notice that the reinstalled version ‘remembers’ my recent scores, so am assuming that some file is remaining.
