Hi @borisss, thank you for providing additional information. I think you could save it all to a text file and attach the text file instead.
I have another request, could you please reproduce the crash after starting the editor using this command in a terminal:
LIBSERIALPORT_DEBUG=1 /Applications/Midihub\ Editor.app/Contents/MacOS/Midihub\ Editor 2>&1 | tee mh.log
It will produce a ‘mh.log’ file in the current location of the terminal (run pwd to see full path)
Please attach the mh.log as well as the full crash report for the same run.
