Sigh – I searched for quite a few variations on that term to see if it'd already been reported and that post never turned up. Thanks for posting the API docs, too – I was just about to share that link and based on http://unity3d.com/unity/whats-new/unity-4.3 it looks like FullscreenWindow is expected to work that way: “Mac Standalone Player: When in FullscreenWindow fullscreen mode without showing menu bar and dock, disable Application switching, as it would not correctly keep the Dock hidden.”

This doesn't appear to have been previously reported but v333's full screen mode on OS X doesn't prevent the menu bar or dock from showing every time you move the mouse near the relevant screen edge, which I tend to do a LOT in IE-style games. OS X has a kiosk API which allows full control over this feature, unlike the regular fullscreen API: https://developer.apple.com/library/mac/technotes/KioskMode/Introduction/Introduction.html
