Expand interface to full screen on OSX!!

Hi Folks

Difficult to explain.

But you know when you open Blender (Mac OSX) and is appears as a window? Well once it dose I click the expand button so it fills the hole screen. Is there a setting that I can set so it dose this on boot for me?

After going to fullscreen mode, save the scene as your default (Ctrl+U in Windows . . . not sure what the hotkey is for Mac).
