I am trying to track down some software that will do the following. Either shut the computer down, log a user out or cause iChat to quit after a set amount of time during a 24 hour period. My parents want a program to do this so they can limit the time my little brother (12 y.o.) can spend on iChat every day. My little brother will sneak on while 'doing homework' or hide iChat behind other windows such as Safari. It has become very difficult for my parents to watch over his shoulder because of this. Is there a program or apple script or such that can do this? Or any other ideas? I have suggested just taking the computer away (it is an iBook) but my bro does use it for class work and such legitimate purposes at times. I have also thought about manually blocking his user log in from using iChat but then again that requires watching over his shoulder to see how long he has been on iChat. He should be allowed on for an hour or so for every 24 hour period. Thanks for your help!!!
