I just bought a new iMac this evening and am trying to get through the initial setup but this thing is TERRIBLY slow. I'm wondering if I purchased a bad one or something. When im going through the set up menue (selecting country and connecting to internet), i click continue and it sits there for 30 seconds before it actually registered that I clicked continue. When i first plugged in the power cord and it started up...it sat at the white boot up screen (with apple logo and loading wheel) for 15 minutes before it finally started the setup process. Is this normal or did I get a DOA computer?
