Unfortunately, I have an Intel Mac. I researched this item extensively prior to purchase and nowhere does it tell you that it has trouble with Intel Macs. The only driver on the M-Audio site is from early 2006 and does not support Tiger 10.4.11 which is what I am running. I installed the CD-ROM that came in the box, but the unit would not show as being hooked up to my Mac and I could not use any of my Pro Audio programs with it. I couldn't even open the M-Audio control panel on my computer. I then went and installed the most recent Intel driver from the M-Audio site and it got a me a little further; I could now open the control panel so that it could tell me that the device isn't plugged in. All of the lights are on on the device but it is not hooking up right to my computer somehow. Me thinks this is an Intel issue.

Of course now when I go to research this issue I find all the Intel problem reports that I didn't see somehow before I bought this item. Bottom line, this is an outdated item (it is a few years old and has not been updated) and it has outdated software support. I'm not sure if just the latter is the only problem or if the two issues work in concert with each other. I wish I still had my G5 so I could try this thing out and confirm that it really is an Intel issue, but I don't. I just have my 2.2GHz Santa Rosa MacBook Pro.

I am returning this to Amazon and now I will have to start looking for a mobile audio solution again. I knew this thing was too good to be true when I saw the price, and I should have gone with my gut.
