Simple, effective parental control for your Mac

Today, I whipped together a simple, effective parental control script for our shared Macbook Air.  For many months, our homeschooled son has been easily distracted by videos and messages when he is supposed to be working hard on crafting a good paragraph.  Apples parental controls are a massive #FAIL – deselecting the default apps do not work and you cannot just simply turn off the Internet.

All the script does is turn off the Internet.  The “garrett” account, limited to 30 minutes, has Internet access.  There is a shared account for homeschool work, which this script ensures has no Internet access.

#!/bin/bash

counter=0
while true
do
  if last | grep garrett | grep "still logged in"
  then
    echo "garrett logged in, do not kill internet" 
  else
    echo "garrett NOT logged in, kill internet"
    networksetup -setairportpower en0 off
  fi
  counter=$((counter+1))
  echo $((counter)). sleeping 10 seconds $(date)
  sleep 10
done

That’s it.  Just turn off Internet access on a single computer.
