I don't seem to have a brush tool

Hi, 

I have lightroom for Mac on my desktop and am trying to edit my photo. 

I don't seem to have a brush or an eraser, nor any healing tools. I looked everywhere. Under masking it says that there will be some new tools available online, including brushes. 

Does that mean that there are no brushes? 

I desperetly need to edit this one photo with a spot that needs removing. 

Please help. Thank you.
