Mac OS X comes in various flavors, which varies the kind of hardware you'll use to run it on. That's why installing OS X 10.8.5 on a MacBook Air (released in 2012) is a lot different than on a 15-inch MacBook Pro (released in 2010). To run OS X on a Mac, you'll need at least a 1,4 GHz Intel Core 2 Duo processor.
You'll also need a screen that can display at least 1366 by 768 resolution (the resolution of the 2012 MacBook Air). If your MacBook Air has a screen that displays at 1152 by 720 resolution, you'll need to use a tool called "Out of Sync".
