No Sound Midi file

Help Please. I just downloaded and installed AUDACITY Version 2.3.3 on my MacBook Pro with High SIERRA
I load a midi file in Audacity but I cannot get any audio. I can see it playing, but cant hear anything…
I have set Transpot>transport option to Software Playthrough but nothing… I believe volumes are up. Volume works with other programs so its not the laptop, but not Audacity.

Any help would be appreciated

“MIDI” is not “audio”.
MIDI data is a list of commands that tells a synthesizer what to play. In order to play MIDI, the MIDI data needs to be sent to a synthesizer of some sort.
Mac computers do not have a MIDI synthesizer by default, so to play MIDI you need to add one. See this part of the manual for details:
