How do I upgrade an iMac 3.06 GHz Intel core duo beyond Mac OS X version 10.7.5
I run software update and am advised there is no update available
All browsers, Safari, Firefox and Chrome say that they no longer support OS X 10.7.5 so I need to find a way to upgrade what is otherwise a perfectly good Mac
