Re: writing EDK compatible application.

Well, if EFI Shell 1.0 works, why not use it?
Mac EFI exposes the ConsoleControl protocol, which lets you switch between text and graphics mode.
That might be the reason your text outputs don't show, because graphics is the default mode on Mac EFI,
though I could never test this myself as I lack the hardware.

Marvin.
