Set Google DNS on macOS system and it should take less than 5 minutes.
Just before that, lets read a little bit about DNS.
What is DNS?
DNS stands for domain name system and it is used to translate domain name (website) into IP address so computer/servers can understand.
Each website has its own IP address and it would be difficult for humans to remember them. Therefore, DNS comes handy where you just need to remember the website name and the DNS system will convert it to an IP address so your computer can understand and land you the website you wanted to visit.
Think about having to remember all the phone numbers of your friends? it would be difficult. So you would save their numbers with their name in your phone book. The next time you want to call/text them, you’ll just need to find their name(s) and your phone will understand.
Why Set Google DNS On macOS (or any other)?

Some ISP has some sort of filters running on their background which can delay DNS queries over the Internet. Switching to Google DNS often resolve this issue.
Reliable DNS service
If you’re getting frequent intermittent connection, one of the way to check is to change your DNS server. If it helps you, your ISP servers are not reliable or maybe overloaded.
Some DNS services provides an extra layer of protection and known to block phishing websites. This can keep you safe online.
Access Blocked Content
Just like a VPN service, using Google DNS allows you to access blocked websites especially in a country where the Internet connection is restricted. The only difference with a VPN, it comes with security and your connection is encrypted.
