Hi, Is anyone familiar with the Powerbook G4 motion sensor? I have gone into the terminal and typed in the required entries but the SMS isn't in the list. I'm using the laptop for my band and its only crashing in a live environment. The vibrations from the drum kit and bass guitar are causing Pro Tools DAE errors. The error message is: "DAE cant get audio from the drive(s) fast enough. Your drive may be too slow or fragmented or a FireWire device could be having trouble due to the extra FireWire bandwith or CPU load. (-9073)" Is there any way of turning off the motion sensor or does it simply not include one?
