Can't right click on touchpad on Macbook Pro late 2011

[dissent]

Hi all,

As mentioned in the title.  I have a Macbook pro late 2011.

Everything is running very nicely except I can't right click with the touchpad.  I can't find a setting to either. 

Has anyone had success in getting this to work?  On other distro's I've tried it was fine.  Just Linux Lite so I'm guessing it's something simple I can do?

Thanks so much
