To update the DNS server on MacOS you’ll first need to open System Preferences, this can be found by pressing the apple icon on the top left of the desktop.
Next you’ll want to find the button for editing Network Pereferences. You can search network to find this.
Select the network you’re using and press Advanced.
Navigate to the DNS tab and press the + button to the left of IPv4 or IPv6 addresses. Then enter 8.8.8.8 and 8.8.4.4. From here press OK and you should be all set.
