    I do not think that your Mac is capable of upgrading all the way to Mountain Lion. It is too old and is below Mountain Lion’s system requirements.
    But you certainly can upgrade past Leopard. I’m curious, though, as to why after skipping so many system upgrades you have decided to suddenly upgrade all the way to the top now?
    Anyway, your first step would be to upgrade to Snow Leopard. To do that you must purchase a Snow Leopard upgrade disc. You can get that from Apple pretty cheap:
    That will be a good upgrade in itself. And it might be as far as you can go.
    After you have Snow Leopard, then do the online Software Update to get the very latest version of Snow Leopard. That will give you the Mac App store.
    Use that to search for Mountain Lion. But if you are not able to get Mountain Lion because your Mac is too old, then I think you are stuck with Snow Leopard as Apple no longer sells Lion.

      I like to have 2 browsers on my machine so I can stream the BBC and do other searches…. Firefox says my system is no longer supported and Chrome won’t give me a copy for much the same reason. I learned from the MAC store, Mountain Lion was available if I had 10.6.6… so I want to move up as far as it takes to get a second browser. Thanx for looking at my needs.

    How do I upgrade from OS X 1.6.8 to Lion?

      I assume you mean OS X 10.6.8.
      You probably can’t. The way to do it would have been to use the Mac App Store to upgrade from Snow Leopard (10.6) to Lion. But when Mountain Lion came out, Apple stopped selling Lion. So you just go from Snow Leopard right to Mountain Lion. That’s what you want anyway — so if your machine supports Mountain Lion then that is your answer (use the App Store to get Mountain Lion). But if you are using a Mac that supports Lion, but not Mountain Lion, then you are out of luck.

    Sam according to this article written a few days, you can still purchase Lion:

    Apparently you have to telephone Apple in order to get it.
