Ok, so my new iMac continues to freeze up when I open iTunes even after a clean install. This isn't even about using iTunes. The machine will freeze at some point soon after simply opening the program. I am running the latest version of Snow Leopard and iTunes and all software is up to date. As some iLife apps were also freezing the machine early on I did not install these. I did try to run a Hardware Test from the DVD but it would not start (held d down while starting the computer with the DVD loaded but the icon never showed). Any suggestions?
