I currently have OS 10.5.8 and need to update my OS to Mountain Lion.  When I run software update, I receive a message that no updates are needed.  How do I update my OS?


Any help is appreciated.

MacBook, Mac OS X (10.5.8)

    Welcome to the Apple Support Communities


    Mountain Lion is a paid upgrade. http://support.apple.com/kb/sp575 If your Mac is supported, call Apple to buy Snow Leopard. Make a backup, insert the DVD and upgrade. Finally, open  > Software Update and install the most recent version.

    Hi, i have the same problem too. My Macbook is bought in 2005 and it doesnt have a DVD drive (only CD).

    Is there any way to upgrade bypassing the DVD?

    I have yet to call the local Apple to buy the Snow Leopard.

    As my Macbook is 2005 version, i read the Mountain Lion requirements, and it seemed my Mac hardware is not supported.



    btw, i was going to get the latest Macbook Pro today, but i read last night that the 13inch Pro with Retina is rumoured to be shipped in Fall.  I can wait, but in the meantime, I'd like to get my current MacBook up so i can have the latest iTunes to bring my music to my new iPhone 5.


    thanks in advance for any lead.

    Start by checking if you cn run Snow Leopard:


    Requirements for OS X 10.6 'Snow Leopard'




    Whilst Apple have withdrawn Snow Leopard from their stores, you can still get it from Apple by calling 1-800-MY-APPLE (if you are in the USA) and they will supply the SL DVD for $20 for a single user, or $30 for a family pack that covers up to 5 Macs.  You can also purchase the code to use to download Lion from the same number (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:




    If you are outside the US call your national Apple Helpline:




    If you're in the UK, use this number: 0871 508 4400


    When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.
