[Here](https://unix.stackexchange.com/questions/17115/disable-keyboard-mouse-temporarily/17140#17140) I posted an answer on how to disable mouse and keyboard input using `xinput`, with the presumption that if the question is about UNIX, X specific answers are good.  However, turns out, the OP was interested in doing that on OS X, whose GUI has nothing to do with X.

So, **if a question is OS X GUI based, does it belong here?** When can we say "ask that on [Apple](http://apple.stackexchange.com/)"?

[Here](https://unix.meta.stackexchange.com/questions/15/macosx-whats-on-topic) is a closely related question, but the above point wasn't clearly resolved, so I'm following Gilles' suggestion to raise it here.
