Scores don't open from Finder in MS4 (Mac)
Normally a file which is created in a specific program will open in this program once double-clicked in the Finder, even when the original program is not yet running. With MS4 this is not so, the program needs to be running before the user is able to open a file. This might not be a big problem but I definitely prefer the regular Mac way.
I will add to this observation, on Mac OS 12.6 (Monterey). If MuseScore is closed I CAN click on a file from Finder and then MuseScore will open, but it goes to the score landing window and then I must choose the file from "open other" or "new & recents" if it shows up there. But yes, it does not open the file directly if double-clicked on from Finder.
