If you’ve connected your Mac device to your Content Policy through DNS, you may have wondered whether you could prevent this connection from being disabled. Fortunately, it is possible to enforce DNS settings on Mac so they can’t easily be changed.

There are generally two approaches to restricting DNS changes:

  1. Using App blockers for Mac to prevent easy access to Mac settings that allow changing DNS.
  2. A more difficult, but reliable method, is to set up a managed Macbook and enforce a DNS configuration that can't be changed using the Macbook. 

Block Access to System Settings

Freedom Blocker lets you choose applications installed on your Mac to be restricted when a "freedom" session is enabled. You can block the Mac's settings app, effectively restricting access to changing DNS settings.

Use Managed Mode to Enforce DNS Restrictions

Managed MacOS devices can enforce a DNS settings configuration that prevents the user from turning off filtering by pointing the computer's DNS to different IP addresses.

If you have set up managed MacOS device, you can use iMazing to generate the following config file and then distribute it to the device using Manage Engine.
