My mother is switching to mac soon, mostly likely an iMac to use as a family computer for her and my youger sister. She likes what sees so far especially in parental controls. However, she wants to be able to keep tabs on my younger sister to make she isn't going to places or saying things she shouldn't be on the web; she wants a second layer of security (she worries that she can get around things parental controls because she is very computer savvy). I figured a keylogger would be the best thing because we could keep track of everything she types on the mac. Does anyone know any good (free) keyloggers for mac? I appreciate the help.
