    You might try reviewing the Mountain Lion Requirements to see if your hardware is supported.

     

    • Mac Pro (Early 2008 or newer)

     

    If your Mac does qualify, what is the error(s) you're getting when trying to purchase/download/install Mountain Lion?

    If it's not compatible with your machine, then you have two choices:

     

    1. don't install it, or

     

    2. buy a newer Mac

     

    Those, unfortunately, are the only two ways to "fix it".

    I'm very sorry babowa, this is a lame reaction. If you do not want to help stay out of the apple support

    You asked how to fix it. I did want to help and gave the only logical answer possible because there is no way to fix it.

     

    Good luck.

     

    FWIW, these forums are user to user only and we volunteer our time to help; Apple tech support does not participate.

    babowa's response was perfectly correct. You can't install ML because your Mac does not support it, as the message tells you. Having an Intel CPU is not enough. Your Mac must also have an EFI capable of booting 64 bit. That means your Mac has a 32 bit EFI and cannot run ML.

     

    Check the link keg55 already supplied. If your Mac is older than anything on the list, ML is not possible.

    If your Mac hardware is not listed (model and year) in the link I provided for katieIII, then your hardware is too old to use with Mountain Lion. So, you won't be able to run Mountain Lion and would only be able to run Lion or an OS X older than Lion (e.g. Snow Leopard).

    Point being that the Mac pro was supposed to already be 64 bit so the 32 bit argument regarding Mountain Lion I find as a bit confusing.

    Yes, it is somewhat confusing. The CPUs themselves have been 64 bit capable for quite a few years. So Win 7 64 bit has no trouble running on a Mac with a 32 bit EFI. Windows actually pays no attention to the EFI since what the Mac does is fool Windows into believing it is booting to a computer with a typical PC BIOS.

     

    And that's the difference. The EFI is basically the computer's configuration and boot sequence hardware, just like a PC's BIOS. Newer PC's are finally starting to use EFI, but most I believe are still BIOS.

     

    Anyway, that's why your Mac doesn't support ML. The Intel CPU is of course 64 bit and can run 64 bit software from the GUI, but the boot EFI is 32 bit only, and ML requires a 64 bit EFI.

    so a new machine just for ML is a dubious move to my mind.

    If your current Mac does everything you need, then there's no reason to jump forward. In my opinion, there's very little in ML of interest. More than anything else, Apple has tried to make OS X act like the iOS devices. Too much so, if you ask me. Other than that, the only other important change is greatly beefed up security.

     

    As for myself, I'm slowly making the move to ML simply because some of the newer software I need to use won't run in Snow Leopard. Otherwise, my day to day OS is still SL.
