CoreMIDI crash problem solved (logic, cubase, garageband etc)
I had the same problem as some other users with CoreMIDI and contacted apple support, after random troubleshooting solutions this is what worked:
restart mac in safe mode, open whatever daw you are using. Than restart in normal mode solved it for me
here's how:
Start up your Mac with Apple silicon in safe mode
- On your Mac, choose Apple menu > Shut Down. Wait for your Mac to shut down completely. ...
- Press and hold the power button on your Mac until “Loading startup options” appears.
- Select a volume.
- Press and hold the Shift key, then click Continue in Safe Mode.
