I have been trying to update my MacBook Air os x 10.6.8 to mountain lion but it won't work, it's saying that it's not compatible with my computer but I checked the requirements! help please!!
Choose About this Mac from the Apple menu, click on More Info, and check the model identifier against MacBookAir2,1, which is the earliest MacBook Air that can run Mountain Lion.
A computer incapable of running Mountain Lion which has a Core 2 Duo(not Core Duo) or better CPU and at least 2GB of RAM can run Lion 10.7, which is available by phoning the online Apple Store and ordering a download code for it.
