    OS X Mountain Lion system requirements

    To install Mountain Lion, you need one of these Macs:

    • iMac (Mid 2007 or newer)
    • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
    • MacBook Pro (Mid/Late 2007 or newer)
    • MacBook Air (Late 2008 or newer)
    • Mac mini (Early 2009 or newer)
    • Mac Pro (Early 2008 or newer)
    • Xserve (Early 2009)

    Your Mac needs:

    • OS X v10.6.8 or OS X Lion already installed
    • 2 GB or more of memory
    • 8 GB or more of available space


    And has been observed many times in this Forum, using anything less than 4 GB's of RAM results in very slow system speed.  And more than 4GB's, if your system can use it, helps alot.



    Hope this helps
