I have the 2012 Macbook Air 13 inch base model. Bought it refurbished directly from Apple. There seems to be an issue with the camera. After a reboot the camera will work fine for a certain amount of time (a few hours to a day or two) then it will not be recognized. Programs say "There is no connected camera." I have already tried doing an SMC reset. What else should I do? Take it in to Apple to have them look at it?
