I apologise if this has been dealt with before, but I couldn't find anything in the forum search. I have a friend's late 2009 iMac that hasn't been used for a while. It developed a booting problem and, as she has no computer knowledge at all, switched it off and put it in the cellar. I said I would have a look, but I'm completely stumped. Basically, all I'm getting when I press the power button is a white screen, the Apple logo and a spinning wheel. Not too uncommon, according to my friend Google, but I can't get it to do anything else. The keyboard appears to be paired, going on the LED, and I have put in new batteries, but nothing works. I've tried restarting pressing C and the Option key, but they have no effect whatsoever and I'm left with the same white screen and spinning wheel. She knows little about the iMac and I'm not even sure what version of OSX is on it. Although she has told me that she has not updated it. The install disk is in the iMac and I can't get it out. I'm determined not to let this beat me, but I really need your help!
