I found this on the MacMusic Forum. I tried it and it works!: ---------Begin quote from Macmusic site:--- Go to the website [http://www.m-audio.com/index.php?do=support.drivers] and download Firewire_OSX_1.5, which says on the site is an update for OSX 10.3.8 & 10.3.9, and then open the installer. The installer states this update is good for the OSX versions listed PLUS 10.4 and above. No problems with the driver!!! Works like a dream! snip..... Firewire_OSX_1.5 is the current driver for 10.4 TIger!!!!!!! ---End quoted post---------------- This is the file to download: FireWire_OSX_1.5.dmg Works for me and will suffice untill Digi 002 drivers drop. Then I'll try to run them both for 24 ch of analog out. G5 2x2 3GB/ 10.4.1/+Pro App Runtime patch/ LogicPro 7.1/
