Command line use of MS4.2.1 to generate MIDI-files returns an error
I've made a json-file that contains information on the mscz-files I'd like to have MIDI-files from.
mscore -j myfiles.json
In return, I get:
mscore[17770:530951] WARNING: Secure coding is not enabled for restorable state! Enable secure coding by implementing NSApplicationDelegate.applicationSupportsSecureRestorableState: and returning YES.
According to an entry in Stack overflow this is something a user can’t deal with, but has to be implemented in the source code.
