If you are experiencing slow or inconsistent internet connectivity on your Mac, switching to Google DNS or Open DNS might help in fixing this problem. You can find below the steps to Change DNS Settings on Mac.
Change DNS Settings on Mac
It is a known fact that changing the DNS Servers to a faster DNS Server can often result in significant improvement in internet connectivity and browsing speed.
While you can switch to any DNS provider, Google and OpenDNS are two of the most popular and free DNS providers that you can make use of.
Both these DNS providers are highly reliable and are likely to be much faster than the DNS Servers used by your Internet Service Provider.
While Google provides a fast and dependable DNS service, OpenDNS provides additional features like content filtering, anti-phishing and child protection controls.

Follow the steps below to change the DNS servers on your Mac.
1. Click on Apple Logo in top-menu bar and select System Preferences… in the drop-down menu.
2. On System Preferences screen, click on the Network tab. On the next screen, click on the Lock Icon.
3. When prompted, enter your Admin Account User Name and Password.
4. Next, select your WiFi Network in the left-pane. In the right-pane, click on the Advanced button.
5. On the WiFi screen, switch to DNS tab and click on the + Plus button located at the bottom-left corner.
6. Enter 18.104.22.168 and 22.214.171.124 as the DNS Servers (Google Open DNS) and click on OK to save these settings.
Note: If you want to use OpenDNS, enter 126.96.36.199 and 188.8.131.52.
