On the same machine I created my score with, Dorico now suddenly shows me a dialog called “Missing Fonts”. It shows “missing family”: “Edwin”. I’m baffled how this could have happened as I created the score on the very same machine not too long ago; never deleted any fonts and can’t think of any event that could have caused this either. (A MacOS upgrade maybe? (On “Tahoe” now but I think only recently.)
Doing some further research… it looks like that font is used by MuseScore, which I don’t use. I think I remember I imported some MusicXML from MuseScore though; maybe that’s why I’m getting this dialog?
