    The iMac6,1 is compatible with Mac OSes up to Lion, so purchase Snow Leopard and then Lion (you have to phone Apple to buy Lion if you want to, they'll give you a download code for the App Store). SL can be bought from Amazon, eBay and the Apple Store (I think?).

    Good advice from edex67, just to add...


    then you must get 10.6 if they still have it, install it & update to 10.6.8 so you have the App Store to buy & download the huge 10.8 Installer.


    Snow Leopard/10.6.x Requirements...


    General requirements

       * Mac computer with an Intel processor

        * 1GB of memory (I say 4GB at least, more if you can afford it)

        * 5GB of available disk space (I say 30GB at least)

        * DVD drive for installation

        * Some features require a compatible Internet service provider; fees may apply.

        * Some features require Apple’s MobileMe service; fees and terms apply.


    Which apps work with Mac OS X 10.6?...



    It's been pulled from the online store & Apple Stores, so you have to call Apple to buy it, last I heard.

    Buy Snow Leopard > http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard

    Call Apple Sales...in the US: 1-800-MY-APPLE. Or Support... 1-800-275-2273


    Other countries...



    I highly recommend mre AM though, yours can use 3 GB, but 4GB can be installed for a very slight spped increase...

    It is a pretty simple process. You can get it to Mavericks which I prefer or Yosemite, but, it does require some tools.


    I suggest this website:


    SFOTT is a great tool for upgrading your Mac. iMac seem to be the most versatile when using this program. I know this program works first hand, because I used it on an Older MacBook Pro.
