I have OSX 10.5.8.  How do I update to 10.8 so I may then update to Mountain Lion, etc.?

iMac, iOS 5.1.1

    The first step in updating is to order Snow Leopard from the Apple on-line store ($20 US), install SL and on-line software update that to 10.6.9.  Then, determine if you can go to Mountain Lion by looking at the compatible machines listed in and if you are on the list, go to the App Store and choose to buy Mountain Lion ($20 US), download and install.  If you do not meet the ML specs you can go to Lion if you have an Intel Core 2 Duo or above processer and 2 GB ram, though 4 GB is much better.  That is purchased by calling 1-800-MY-APPLE and paying the $20 fee for the download code that will be sent in a few days in an email with instructions for doing the download.


    You can go from Snow Leopard to either Lion or Mountain Lion directly.

    Some early iMacs cannot run any higher than Snow Leopard 10.6. Lion 10.7 required a Core 2 Duo processor, someting the first Intel iMacs lacked.


    Doing "About this Mac..." from your Apple menu will show your processor type.
