I am building some mini CNC machines for an after school club using a guide on Youtube. The guide is incomplete so I am having to plug the gaps.

Some of the schematic issues have been asked here.

I now understand that once everything is wired and powered up correctly I need to send the picture using Gcode software on a PC / Mac to the Arduino over a serial connection.

I can't seem to get Universal Gcode Sender working on my Mac (El Capitan) any idea how I do this, I have tried running it from the command line but just get an error.

Any help would be great?
