Bought my first ever macbook, switching from windows was huge because everything is different and i don't know how to do anything on this machine! I bought a Macbook air 13" that was made in late 2008, this one here: http://www.everymac.com/systems/app...core-2-duo-1.6-13-nvidia-late-2008-specs.html. The owner left everything on the macbook and i would like to reboot the system to factory settings but it did not come with a usb/ or cd. My first question is how would i reboot the system to factory settings? 2nd: Also he said it has windows 7 on it, how would i switch over to that from the mac os? i looked at options but didnt find it? 3rd: how do i uninstall programs, i do not see a control panel like i do on my windows. 4th: the fan on the macbook is noisy when I put my ear to it, even when im about 30cm away i can hear it but not as loud, is this normal? sorry if the questions seem to be stupid im just new to the scene. answer to these questions would be great!
