Hi, I have iMac 24" which I bought five days ago. I have external hard drive which I wanted to hook up to the mac. Turned it on, the mac did not recognize it, nothing happened. I know this drive works. I tried USB - did work. I tried to hook up the camera - did not respond at all. I noticed on apple site forum that other people have the same problem, firewire does not respond. And as I understand tech support at apple know nothing how to fix it. So here we go, the consequences of buying the product which just came out. I would hate to take it back to the store and hope it is just a driver issue or something which can be fixed via updates. I would also add that games under boot camp don't work at all, just dropping out to desktop.
