Multi Display Fullscreen 0.9.0 OSX

Is there an updated solution for running oF stretched across multiple displays -- fullscreen -- for 0.9.0?

Used to use:

"
OfAppGLFWWindow window;
window.setMultiScreenDisplayFullscreen(true);
ofSetupOpenGL(&window, 1920, 1080, OF_WINDOW);

"

in the main.cpp file.

This is no longer working and setMultiScreenDisplayFullscreen() is deprecated and doesn't seem to be functioning.

Any updated solution for this?
