How to block access to specific websites on Mac

Restrict access to websites on Mac

If you have children using your Mac, you probably don’t want them to access websites you deem inappropriate for them. Of course, adult sites come to mind, but there is also a host of other sites that you probably don’t want your kids to end up visiting.

As a parent and the administrator of your Mac, you are able to block access to specific websites. This blacklist is particularly helpful when you know your kids have been visiting one specific site that you don’t approve and want to prevent them from doing so again.

In this tutorial, we’re going to show you how to restrict specific sites from being visited on a Mac, regardless of the browser being used.

Going forward, when a user tries to access blocked sites, a message will appear in the browser saying you cannot browse this page because it is restricted.

These restrictions work across all browsers. Regardless of the browser being used (ie. Safari, Chrome, Firefox), the user will not be able to access the blocked website.

Similar websites restrictions are also available on iOS. Make sure to read our tutorial on how to block certain websites on iPhone and iPad to also limit access on these devices.
