I purchased my iMac in August, and I've had a case open with AppleCare since early september. I made sure to use the same case number each time I called to bitch, so that I could show it started happening within the 30 Day DOA Period. Anyways, I waited for Leopard to see if it would fix it, it didn't. I waited for iMac Software Update 1.2 / 1.3 - didn't help either. I called AppleCare back up today, my case was promptly upgraded to a Product Specialist who said there was nothing more they could do (since I tried Erase & Install), and the representative said I was eligable for repair/replacement. I told her I choose replacement. She said since I bought it at an Apple Store, I would have to go back to the store for an exchange. (why??? you guys both carry the same imacs...) I schedule a Genius Bar appointment, and I go there this evening. They said the product specialist (I took and wrote down her name) left no notes in the case about an exchange, so they could not authorize one. I was told I'd need to setup another appointment with a Genius, and that THEY WOULD NEED TO SEE IT FREEZE. Now, that presents a problem. My iMac seems to have good days and bad days. Yesterday it would freeze when the dock appeared at boot, today it been more stable. I really don't want to lug my iMac to the apple store, set it up, and not have the problem be reproducable. I was given the name of the General Manager (who "should be in tomorrow" and "we haven't seen him in a while") to speak to tomorrow regarding my issue, but he's only available before my Genius Bar appointment, which doesn't bode well. I really need to find a way to make my computer reliably freeze. I've read about people moving cover flow around really fast, UT2004, other such things, but none of them work for me. I'm really frustrated. I know it freezes, /var/log/system.log shows all the freezes (** ASIC Hang Log Start *), but how do I convince them its freezing? WHY do I need to convince them its freezing? I don't see how I could be trying to pull one over on them.
