I have Leopard in my Macbook Pro (Intel) and would like to upgrade to Mountain Lion.  I have it on the disk that came with my husband's Mac Pro, but if I insert the disk it says it can't be installed on my MBP.  Is that because it's only licensed for the Mac Pro or is there another reason?

    It's because the 10.6 your attempting to use is machine  specific with hardware drivers for that model of Mac only.

     

    You will need the 10.6.3 white retail disks, call Apple via phone to order.

     

    BTW, a 10.5 era machine may not run 10.7 or 10.8, or may only run 10.7, or if it does run either may do so slowely and wont' run your older PPC based software and hardware drivers.

     

    You might even have to upgrade RAM, so be sure of your hardware requirements and expect to replace some software with new copies.

     

    IMO it's best to stick with 10.6.8 on most pre 2010 issue Macs.
