It's true that I have seen far more windowed as default on mac than fullscreen.
I guess there is no rule, however I am doing the same under windows (default windowed), and have therefore only a windowed mode or a maximized borderless "fake" fullscreen at the convenience of a button the user has to push (something like windows media player or quicktime).
I am doing this as well on MacOS and Linux.
This way you don't switch resolution but it has a serious limitation if you are using 3D, max size of a render buffer is 2048 or 2560 pixels and with the gigantic 30" screens of these days that isn't doing it. So I just draw the maxsize render buffer centered with black frame around it.
The good thing with this fake fullscreen is that you don't have weird effects when suddenly something tries to popup in front of your software.
