How to Unblock Websites on Mac Terminal: A Comprehensive Guide

In today’s digital age, accessing websites has become an essential part of our daily lives. However, due to various reasons, certain websites might be blocked on your Mac, preventing you from accessing their content. Luckily, with the use of Terminal, Mac users can unblock websites effortlessly. In this article, we will provide you with a step-by-step guide on how to unblock websites on Mac Terminal, along with addressing some frequently asked questions on the topic.

Step 1: Launch Terminal
To begin unblocking websites on your Mac, you need to open the Terminal application. You can find it in the “Utilities” folder, located within the “Applications” folder. Alternatively, you can use the Spotlight search (press Command + Spacebar) and type “Terminal” to quickly locate and open it.

Step 2: Access the Hosts File
Once Terminal is launched, you need to access the hosts file. This file acts as a local DNS (Domain Name System) resolver, allowing you to override domain name resolutions. To open the hosts file, type the following command in the Terminal window:

sudo nano /etc/hosts

You will be prompted to enter your Mac’s password. Enter the password and press Enter to continue.

Step 3: Edit the Hosts File
After successfully entering your password, the hosts file will open in the Nano text editor within Terminal. Here, you will see a list of IP addresses and domain names. To unblock a website, you need to add an entry to this file.

To do this, first, locate the line that starts with “” This line indicates the localhost. Below this line, add a new line with the IP address “” followed by the domain name you want to unblock. For example, to unblock “www.example.com,” add the following line:

Once you have added the entry, press Control + O to save the changes and Control + X to exit the Nano editor.

Step 4: Flush DNS Cache
After modifying the hosts file, you need to flush the DNS cache to ensure the changes take effect. To do this, type the following command in the Terminal window:

sudo dscacheutil -flushcache

Hit Enter, and your DNS cache will be flushed.

Step 5: Test the Unblock
To check if the website is successfully unblocked, open your preferred web browser and try accessing the previously blocked website. If everything was done correctly, you should now have unrestricted access to the website.
