Sure. I never said it's impossible to set a fullscreen mode. Just that you can't easily take a window and tell it to go make itself fullscreen.

Allegro programs do that if I set a fullscreen mode at the native resolution of my display. At least I'm fairly certain that's what it looks like when I do that.

It's sometimes hard to find, in my experience. Apple's developer site is good, but I find that quite often it doesn't quite have what I want.

I guess the difference between Allegro's windowed and fullscreen modes is this: in the windowed case we use an NSWindow, which captures events for us. In the fullscreen mode we need to capture events ourselves. How easy it is to do this differently (if this is possible at all) I don't know, but that's part of what will determine how hard or easy it is to implement this.

Personally I don't see what's wrong with telling the user to create a new display, except it doesn't look as fancy. ;)
