I'm running 10.6.2 and logic 9.02 on a iMac 24 2.16. About 10 days ago my MOTU began crashing within a minute of power up. I've been talking to MOTU support with little success and thought I would just throw this out there. I've tried the unit with/WO AC, directly plugged in or in series, reinstalled all drivers. The FW bus works perfectly on a DUET as well as other devices. The MOTU works fine on my G4 Powerbook running 10.58 as well as stand alone on AC. Anyone have any suggestions?
