[F]Mayor Game Problems.

Hello, I apologize if this is not the right place to post but I am new here, now I regret to inform that I am experiencing trouble with the game that makes it unplayable. First, the left mouse button is useless when playing, I tried going to the key mapping and it was very weirded out, I took a screenshot so it can be seen: http://i.imgur.com/XM7fjQl.jpg. That is the mayor problem, after that the hangar, and only the hangar has a glitch where the top and bottom part are mirrored as seen in the following screenshot: http://i.imgur.com/kozMdGb.jpg. All I can say is that I am on an iMac and that this happened after I maxed out the graphics, if anyone knows how to fix it I would appreciate it, thank you.
