So I'm working on a clients computer, and it's acting a little strange. She bought a brand new iMac from CompUSA (with Tiger), so she got Leopard and asked me to install it for her. The computer was still on the box, so I turned it on, installed Leopard, and when it restarted, it comes to the Apple logo with the spinning wheel, and it sits there. I can't figure out what could be wrong. It's not too big of a deal because I could just do a clean install instead of upgrade, but that takes more time. Anyone have a quick fix?
