Help/Advice with cross compilation on Mac

Hello

I recently bought a brickpi to make a robot as a project. I have a Macbook with Snow Leopard and am thinking of cross compiling to speed up the development. I am familiar with C/C++ and Python but pretty useless when it comes to hardware/firmware.

If anyone could guide me how to proceed if I wanted to cross compile on the Mac.

Thank you in advance.
