how do I upgrade past OS X 10.5.8?

I currently have OS X 10.5.8 and am repeatedly told visiting various sites that I need to upgrade. Checking software updates, I am "told" I am up to date. Just wondering what I should be doing as I get my current software is a little long in the (leopard's) tooth?

iMac, Mac OS X (10.5.8)

Choose About this Mac from the Apple menu and check the processor.


If it's a PowerPC Mac, it's already running the newest OS it can.

If it's a Core Duo Mac, click here, install the DVD, and run Software Update.

If it's a Core 2 Duo or better Mac, upgrade it as if it was a Core Duo Mac, and once done, if desired, open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, go to the online Apple Store and order a download code for Lion 10.7.


Mac OS X 10.7 and newer don't support PowerPC software such as Microsoft Office 2004. If you upgrade the OS, back up the computer first.
