OK, so I just purchased one of the new iMacs. I'm not a computer geek, the only software I've got for it so far is whatever comes standard. Safari is the internet browser, and there's some sort of Apple mail program. I think both of these could be upgraded, and I'm looking for suggestions. Also, do I need to upgrade my internet security, firewalls, etc.?
I trust you guys and gals, thanks in advance for whatever advice y'all can provide.
