    Firstly I would like to introduce myself, my name is Wesley and I am new to I have come here many times through Google searches & figured it was about time I signed up. I look forward to being a part of the community!

    I have a couple questions:

    1) I currently have Snow Leopard on my one computer and on another computer I just have Leopard. I am purchasing Mountain Lion from the App Store today and am going to install it onto my computer with Snow Leopard. Can I then take my old Snow Leopard disk and instal it onto my other computer?

    2) When installing Mountain Lion onto my computer, will everything (Files, applications, games, etc) remain? Or does it wipe everything out?

    3) I ultimately want Mountain Lion on both of my computers, does that mean I need to buy two copy's? Or can I down the same copy of Mountain Lion from the App Store on both computer and install?

    Thank you in advance, any help would be greatly appreciated!

    The grey install discs that come with Macs are model-specific and will not work on other models. You can purchase Snow Leopard to install on your other Mac.
    Yes, although some apps may not be compatible with ML.

    When you buy ML on the App Store, you can install it on any or all Macs you own.

    As GGJstudios, once you purchase it it's licensed for all the Macs you own. However, Mountain Lion has dropped support for some of the older Intel based Macs. Since you didn't mention which Macs you own, here's Apple's official list of systems supported by Mountain Lion:

    Because Apple make their money selling hardware, while Microsoft make their money selling software.
