JVC- GR-D72 Won't recognize Camera

OK.. I admit, It has been awhile since I have had a mac. I got my new iMac about a month ago, and I can't get it to recognize my camera (JVC GR-D72). I don't have the books for the camera anymore, but the software that did come with it isn't even executable when I put it in. It indicates that it is for Windows or Mac, but the Mac won't do anything, not that I even want to use the software, but I thought maybe it would help the machine to recognize the camera. Stupid question.. but does it need to be connected via firewire??? USB ok?? again ... I had an outdated computer previously so I never went to the computer to put my videos on..... any help is greatly appreciated
