I sell a 2011 iMac today for $725. (Stupid me, didn't count money and he only gave me $705) Well I had to drive almost two hours to get it to him and two hours back. I get home and he's got questions about how to maximize windows? No clue... Didn't know that it was silver either before I came. Thought it was white. Clearly he didn't research. Well now he's complaining about the fan noise, saying it's always on. First off, I never had any issues with the iMac. Used to run Lightroom, Final Cut Pro, intensive stuff. I just have a feeling I'm about to have a headache on my hand. I can here it coming, "I want my money back." Nothing freaking wrong with the machine what so ever when I gave it to him.
