Playback not working

• Jul 5, 2020 - 15:19

So I downloaded Musescore 3.4.2 and the playback hasn't worked once. The playback menu, View -> Synthesizer and View-> Mixer options are all greyed out. My I/O menu is empty. I'm working on a MacBook Air with OS Catalina (10.15).

I have the same problem on OS X 10.13. Musescore was working fine, and stopped playing back yesterday. without having done any updates or upgrades. Quicktime player 7, which I used occasionally to play back midi files quickly, also stopped working at the same time. All other apps (Finale, Cubase) playback normally, either through external synths or their own sound banks. Factory reset etc doesn't work, View->Synthesizer is greyed out, Preferences->I/O doesn't accept anything.

don't know if you've worked it out yet, but what worked for me was to restart my Mac in safe mode by holding Shift at start-up time, and then rebooted again. now everything works for me.
