I've got Logic 6 on an ibook 700 driving my 002 Rack and it works ok but not super. Tried it on my eMac 800 G4, but Logic doesn't recognize the hardware even though ProTools LE does. Be sure and upgrade LE to 6.1.1. That also installs Digidesign CoreAudio setup which is required for third parties to recognize the 002 hardware.
