MuseScore fails to launch on Mac Mojave 10.14

• Nov 3, 2020 - 10:21

Admittedly only done a few searches to see if this is a common problem - but I've got a pressing job on and hope to get this fixed quickly if possible...
I downloaded Musescore 3.5.2 and launched the application. The software starts initialising and the just after creating main window the program seems to hang leaving a blank black box on my screen. Can't then close the application without forcing quit...

Any swift fixes or explanation gratefully received!
Really hoping I don't have to re-subscribe to Sibelius...


I tried the reset defaul start from Terminal command line and got this in return:
dlopen error : dlopen(libjack.0.dylib, 1): image not found
dlopen error : dlopen(/usr/local/lib/libjack.0.dylib, 1): image not found
Unknown options: /, A.

I have the same issue. Musescore 3 has stopped loading on my Mojave Mac.
I have even downloaded it again. It won't event get through the Verifying of the app.
