It may be better to first use the SDL GUI, as that's been better tested.

In the SDL GUI "Devices" dialog, MIDI input & output options should be 
showing "Off", unless you've saved Hatari config with something else 
selected.

When you click into arrows, MIDI input & output should show something 
else than just "Off", *if* MIDI devices are available in the system.

Note: if MIDI devices are provided by host programs (e.g. QSynth / 
FluidSynth SW MIDI synthetizer), they need to be started *before* 
starting Hatari!

(If I remember correctly, PortMidi does not support re-scanning the 
devices once it had been initialized, so Hatari won't support it either.)

Since I do not use MIDI, I cannot justify the time to spend on this. If there is not someone who has the interest in working on this, a simple note should suffice letting Mac users know that portmidi is not available in 2.5.0 when it is finally released.
