What version of JACK are you using?
Does JACK output any errors? If so, can you post them?
I don't have access to a Mac, but I did write the code for the
CoreMIDI driver for JACK 2; so, it's possible that my code is somehow
responsible for the error. If you know a bit about the CoreMIDI API
and/or would like to take a look at the code yourself, look here:
http://trac.jackaudio.org/browser/jack2/trunk/jackmp/macosx/coremidi
Perhaps you'll see something I missed.

Hmmm. Can you try monitoring MIDI at each stage?
