Grasshopper not connected to the internet????

Screen%20Shot%202017-02-17%20at%2013.47.51.pngHi guys, having some trouble...

I'm a bit of a newbie to grasshopper and are trying to create a solar radiation analysis of my building. 

When creating a simulation though grasshopper it says "You are not connected to the internet..."

I am using a MAC!

I initially thought it was related to my active firewall, however, once disabled, still no change.

URGENT request, Please help me out. 

Need a submission by Saturday.

Thanks people :)
