It needs to be available in 10.7 on up.
The Window Server moves most windows entirely without involving the app (until the move is completed). If you want to change how windows get moved, I think you have to take over the whole process. You do [window setMovable:NO] to make the Window Server not move your windows itself. Instead, you get the relevant mouse events and you write typical mouse drag code and change the window frame manually. See the docs for -[NSWindow isMovable].
