    Choose About this Mac from the Apple menu and check the processor.


    If it's a PowerPC Mac, it's already running the newest OS it can.

    If it's a Core Duo Mac, click here, install the DVD, and run Software Update.

    If it's a Core 2 Duo or better Mac, follow the Core Duo instructions, open the Mac App Store, and try purchasing Mountain Lion. If you get told it's incompatible, phone the online Apple Store and order a download code for Lion.
