slightly different on my mac.
Check out the attachment

No midi folder in \library\applicationsupport \ToonTrack\EzKeys2
A database folder with folders underneath containing similar naming to win files.
under each folder a file labelled midiDB.

As I mentioned the uitility returns a "too large" when you try to procsss the midiDb file.

Perhaps it just doesn't work on Mac.... Perhaps I'm missing something.
