This section lets parents specify how long their children can be online, and when.Using the sliders you can specify for how long your children can use the family computer during weekdays and weekends.
Here you can apply simple settings to your Mac, locking out some of the more advanced features for your child.
This will stop them changing any settings or altering things that they might not yet understand how to use.
Similarly, if you feel that there are sites which should be restricted but aren’t, then you can head back to the Parental Controls menu and under your child’s profile go to Web Customise and add links to inappropriate websites.
This way, you’ll gradually build up a list of approved and unapproved sites, giving your child the freedom to explore the web safely and learn how it works while parents can still control what they see.
You can set intervals from half an hour up to eight hours.
