I purchased a new 27" iMac 3 weeks ago. I took it out of the box, plugged it in and NOTHING. I finally got it to power on. Everything worked fine for a couple of days and then the same thing happened again. I decided to take it in to the Apple store. They checked it out and naturally, could not reproduce the problem nor could they find anything wrong when they tested it. I have heard about Apple's "legendary service" but am a bit miffed that they are giving me my machine back without doing anything. I guess I could send it back to the online seller I purchased it from but don't want to go through the hassle of re-installing Parallels, Windows, etc. Does anyone have any other ideas? THanks.
