OS X Mountain Lion Support

Get Started

Requirements

To install Mountain Lion, make sure you have the following:

  • A Mac that can run Mountain Lion

    Your mac must be one of the following models:
        • 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)

    Find out if your current Mac qualifies by clicking the Apple icon at the top left of your screen, choosing About This Mac, then clicking More Info.

  • Lion or the latest version of Snow Leopard

    While you have the About This Mac window open, check what version of OS X your Mac is running.

    If you are running Lion (10.7.x), you’re ready to update to Mountain Lion. If you are running Snow Leopard (10.6.x), update to the latest version of OS X Snow Leopard before you purchase OS X Mountain Lion from the Mac App Store. Click the Apple icon and choose Software Update to install Snow Leopard v10.6.8, the latest version.

    If you’re running OS X Leopard and would like to upgrade to OS X Mountain Lion, first you’ll need to upgrade to OS X Snow Leopard. You can purchase OS X Snow Leopard for $19.99 online via the Apple Online Store.

  • 8GB of available disk space

  • 2GB of memory

  • Mac App Store

    You need the Mac App Store to buy and download OS X Mountain Lion.

  • Apple ID

    You need an Apple ID to purchase and download content from the Mac App Store, and for certain features of OS X Mountain Lion. Find out how to create an Apple ID or check to see if you already have one.

If your computer does not meet these requirements, you will need to upgrade your computer first.
