Mac Minder represents the end of a long search for a utility to help me regulate how long my kids use their computer. I have looked at many other programs and found this to work best. I have set up schedules for each child which indicates what periods of the day and for how long each child can use the Mac. For those special times when they ARE actually doing homework <g>, I can easily give the child more computer time without disrupting their work flow. It is stable, elegant, secure, and I have found support to be excellent.
