You can use kqueue() to monitor a vnode for various modifications. In this case, you'd monitor the directory which contains your app bundle, since moving it means removing the entry for it from there. Obviously, not all modifications will be your app being moved, so you'd have to check. That said, this seems like checking that the user hasn't poured molasses into their computer's vents. If the user is determined to break their system, there's nothing you'll be able to do to stop them.
