I just got a G5 2.5, with 4 gigs of RAM, and installed Logic Pro 6. I am using a Digidesign 002 firewire interface, which worked FINE with core audio on my G4 800mhz machine (on OSX 10.3.4 also) On the G5, however, core audio gives me errors everytime I open Logic. I downloaded and installed the latest Core Audio 6.5.2 from Digidesign, same problem. Can anyone help??
