If you are having problems with your computer, do not bring it here - make an appointment at an Apple Genius Bar instead. My iMac would not operate so I left it with Midtown for a few days. After they advised me it was ready for pick I brought it home and it still would not operate. I took it back to them again and after 3 days and a follow-up phone call they told me that it was fully functional and ready for pick-up. But when I got it home, it still did not work. A friend advised me to take it to an Apple Genius Bar and within a few minutes their superior diagnostic program confirmed that the hard drive was corrupted and could not be fixed. Also, the Apple diagnosis was free while Midtown charged me $65 plus tax.
