I have an older mac desktop and have noticed that more and more programs are no longer compatible and able to run on my system- 10.6.3. The latest version of Evernote won't load and I can get Mac dictate because it needs a newer version. For most purposes my Mac is just fine, but since it appears I can't work with newer software or apps (looking to buy a used desktop) can anyone suggest the most necessary upgrade version that will be compatible without buying a brand new machine. Thanks for any suggestions or help here!
