Minecraft sprinting and Hitting Problems

I am using a iMac. My sprint button is set as control (ctrl). When I try and sprint and hit at the same time it will not hit. It is as if I didn't click the mouse, my hand doesn't move. However, I can build. Could this be to do with shortcuts and if so, how do I fix it? Many thanks!


Solution 1:

You should change the sprint key to a different one (I suggest ⌥ option), because in Macs, Ctrl + Left Click is considered as Right click.
