Arduino UNO Mac laptop internet connection over USB not working

Hi
I am trying to reproduce what was done in this video from Blynk

This is the error message, The issue is MAC related. I was able to get it to work on Windows computer.

What version of the Blynk library are you using?

Pete.

version 1.0.0-beta.2

You should uninstall that and install 0.6.1 instead.
