So I purchased a used Imac 2009 model. It's currently running 10.6.8. 2.26ghz intel core 2 duo with 2gb of ram (Upgrading to 8gb soon). I'm new to this whole mac stuff, but my question is from this old outdated os what can I upgrade to?
Have you checked the app store for updates? I would try that first and see if it offers and update. Without knowing the specific model it is difficult to tell what is the latest version of the Mac OS you can update to.
