Anyone play on Macbook?

I am looking for a way to switch the functions of left click and right click on my macbook. I have quite a bit of experience playing twitch games on a trackpad and am confident I would be just as good as any player with a mouse if I could only use left click as my primary function for moving around/auto attacking. I've attempted an input.ini text file in my /Contents/LoL/Config folder with:

evtPlayerSelectClick = [Button 2] evtPlayerMoveClick = [Button 1] evtPlayerAttackMoveClick = [Shift] [Button 1] evtPetMoveClick = [Alt] [Button 1] evtPetReturn = [Alt] [Button 2]

And I've checked the Mac OSX box controls settings in game -- but to no avail. Anyone found a working solution for this?
