Testing with Unity 2019.4.2f1, macOS Catalina 10.15.6.
I received a Unity Project with MIDIJack in it. When running a scene with MIDIJack components I got a macOS popup stating that MidiJackPlugin.bundle "cannot be opened because the developer cannot be verified"
The macOS pop-up didn't provide an option to 'Trust' this .bundle, and wanted me to move it to the bin :)
To fix this and get my scene running I had to go to macOS Terminal and run the following command:
xattr -r -d com.apple.quarantine /path/to/MidiJackPlugin.bundle
