    If you're using a G3, you don't.

    If you're using a G4 or G5, purchase Mac OS X 10.5 from a source such as Amazon or eBay.

    If you're using an Intel Mac, phone the online Apple Store and order a Mac OS X 10.6 DVD.

    You need to know what level of OS X your Mac can run.


    If you can provide details on exactly which model of the iMac you have we help you then.

    Start by checking if you can 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    Whilst Apple have withdrawn Snow Leopard from their stores, you can still get it from Apple by calling 1-800-MY-APPLE (if you are in the USA) and they will supply the SL DVD for $20 for a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.


    To use iCloud you have to upgrade all the way to Mountain Lion:
