For those whose Right-Click on their Mac (or possibly others) WON'T work.

So, I just tried to fix a problem with a dysfunctional right-click. There is a very simple solution. In your game, go to the settings in the Hot Keys menu. Scroll down to movement controls. Make sure that in your movement (where applicable), you set the hotkey to MB2. This can be done by clicking the area in the chart, and right-click.

This fixed my problem immediately, and it was not a complicated process at all.

Hope this helps someone!
