Looking at the demo code, the initialization of a window is never actually done, and the Mac OS code is #ifdef-ed out.

Removing the check for 64bit that undefined the initialization, and replacing the carbon-based code that create a window to the initialization of a Cocoa NSApplication and NSWindow seems to get something working.

The application can't terminate on it's own when you hit Q or ESC, but it's not crashing, and the events are shown int the console.

The quit problem seems fixable, the mouse cursor seems to be hidden by default, and the code that prints event on the console only prints a raw integer value when it gets an event. Other than that, everything seems to be working flawlessly.

See commit f8637a8

Have to say that anybody with actual knowledge of Objective-C(++) and Cocoa are welcomed to help ;-)

For other reasons, I have recently acquired an actual mac. Gonna be able to dive into this a bit more

Any update on this?
When I run the demo the FFConsoleApp results in a seg fault and the ConsoleApp makes my mouse disappear as soon as the console window get selected.
