Curve Fitting Tool for Mac

Hi,

I cannot seem to find the "smooth" options/tab in the mac Curve Fitting Tool. I watched the demo online and after pressing the "data" tab, where it shows there is an option to select data/workspace variables- then there is another tab on this new window entitled "smooth". I cannot seem to find smooth in the mac version of the curve fitting tool. On the mac version there variables can be selected from the main window.

Anyone know where is "smooth" tab or option in the mac curve fitting tool?

Thanks
