Draw arrows on mac. Control click doesn't work.

Sorry for the dumb question, but I've searched this forum and google and can't find a way to draw arrows with my mac mouse during a live game. I have "draw arrows" enabled, but it still doesn't work. 

any ideas besides "get a new mouse"?

You have to right click while drawing with your mouse.

Also if you don't have a mouse, then I don't know. Because I don't have a mac mouse.

I should have mentioned that I knew you had to right click, sorry. Normally right click on a mac mouse is command+mouse button. Doesn't work...I've also seen articles suggestion using shift or option + mouse button and it doesn't work either.

Click in the right down bottom of the ‘mouse’ try to use it…
