Good afternoon. I am not good with computers. Is it an option to revive my late 2013 Mac 27 inch screen? It's the one with 3.4 GHZ quad intel core processor, 8 gig ram. I contacted a computer shop and they said Apple no longer supports such an old Mac. This is our back up computer just used for printing documents and going online. Would it work to add a newer processor, add more RAM, and maybe update the video card so it no longer runs at a snail pace? Or, is it over and we should just get a new one?
