To crash/freeze victims: I believe have narrowed down my crashing problem to MIDI: When I don't load the MOTU MIDI USB driver (1.0), it doesn't seem to crash (so far). Of course, my MIDI instruments ain't there. I've looked for a driver update (both on MOTU and Apple's sites) but cannot find. (I use MTP AV). I hope it is this simple, but if this is actually the problem, what are my options? Almost there! -BJ
