Unity 4.3 made a change in Mac Standalone Player: When in FullscreenWindow fullscreen, so there are 2 versions of "fullscreen" one with CMD+TAB, dock, menu autohidden and one which completely removes everything. Are we able to currently switch between these 2 modes, and if not i suggest we give the user the choice. A little background for this problem: When hovering your mouse at the top, mac osx title manu bar auto appears, which clutters and obstructs the ui of KSP. This also happends in 7D2D which in turn is also running on Unity engine, but 5.0 version however.
