I know I can set a Timer and get the [NSEvent mouseLocation]; but at school someone taught me that polling must be avoided as often as possible!

It certainly must, but I am afraid that in this case Apple leave you no alternative :( Please do file a bug/enhancement report -- this question has been raised a dozen times, and I can think of some very useful applications of being able to intercept the mouse, but polling would be very bad as it would probably drain the battery on portables... not to mention that for one application I have in mind, polling would simply not work, since I need *every* single mouse moved event.

I think about the Apple application called Pixie, it gets the mouse cursor position as I want,

Pixie has _CGSCurrentInputPointerPosition as external symbol, which would hint polling, and the UIElementExpector example from Apple also sets up a timer and calls GetMouse() 10 times pr. second.

That said, I do not know much about Carbon events. When registering for keys with application as target, they arrive even when the app is inactive. But I do not know if the same holds for mouse events.
