... somehow I have to help my son (12) to limit the time he spends on his (yes, HIS) computer. His grandpa got him a used iMac for Christmas, and because it was his computer, I let him be the admin for it. 5 months later, we are desperate. I don't want to take the control away from him, but I need to be able to limit his computer time. I wish there was a program that would force the iMac to shut down after a certain amount of time (NOT AT a certain time), that is password protected by another password, not the admin's password. I know that creating a new user for him and take his admin password away would be the easiest thing for me, but I just don't want to have to do that to him. Any help would be very, very much appreciated. Thank you!
