@Sharonia thanks for your reply :) another user, puzzler, on a new thread I started in 3, gave a link for the O.L. I didn't uninstall the game, only the EA App. Guess what? The O.L. showed the EA App had d.l.'d the mac verison of 3 and via the "manage add-ons". City 4, S2 and S4 were fine but 3 ... mac.
Also, I had to write something here, because everytime I come back the rough draft of something else I was going to say but didn't,shows up in the comment box even though I delete it each time.
