    Lion (OS 10.7) is the most recent OS.

    But, you must have Snow Leopard (OS10.6.6 or later) installed before you can install Lion. Snow Leopard requires an Intel processor and 1GB of memory. Lion requires at least an Intel Core 2 Duo processor and 2GB of memory. Snow Leopard only comes via DVD. Lion only comes via download.

    So, if you have the minimum hardware requirements, then buy the Snow Leopard DVD and do that upgrade. Do software updates to bring it up to OS 10.6.8. Then go to the online Apple Store and download Lion to upgrade.

    Please note: Lion discontinues support for Rosetta, so older apps will not run. You may want to have two partitions on your iMac with a clone of your Snow Leopard OS on each. Then upgrade only one of the partitions to Lion. That way you can still start up in Snow Leopard if you need to run an older app.
