Laruel -
I think the kinda app your looking for might be an extention, most of the keygrabberes I have looked at on Mac are...
if so the best way to check is to start up the OS with the extensions off (hold the shift key down to do this) and then check all the extensions you have...and make sure you check for invisible ones two...
That might take care of a low-skill snoop....
