I've got FC3 myself and i agree it's a good entry point for newcomers. I've got no problem with MAC singleplayer wise, if you read my post, i absolutely second it regarding this.
But regarding the point i mentioned - server gameplay/PvP - FC3 is already a big inbalance. I found a pretty nice YT comment, that explains it well... and MAC will just make it worse (plus: aircraft that easy you can fly them with your mouse attracts a certain kind of people, and they are cancer to niche games. Servers will turn into a kindergarden VERY quickly)
