Bug Settings throughout Apple and Different Pc.

I played on my account on my friend's apple mac computer a few days ago then I went on my dell laptop today to play then something weird happened. I launched into the game and when I clicked left click onto the in-game shop which I always do because I'm so used to that it didn't work. Then I later figured it was my middle mb3 scroll button and it worked, but sometimes it messes up my camera zoom in and out. There isn't a way to change those settings when I checked. It would be better if the settings could be changed with macs only and pcs with pcs. Since the mac controls are a little different than pcs like the apple mouse. Thanks. Please let me know as soon as possible if this could be changed so I can get my normal controls back.
