2.3.2. Cons: Speed wise it can be slower with 3-D rendering and graphics intensive programs even if you have the best Mac you can buy. The EULA agreement states that you are not allowed to install its OS on any PC. So no dual booting allowed on another non Mac system, in fact they can sue you for this since its illegal.
