How to Block Websites on Mac (macOS Sierra Included)

“Is there a method or a website blocker to block websites on mac? When I am trying to work on my Mac, something always drags me from working, like watching YouTube videos, listening to musics, etc. This is very annoy and makes me less productive. Can anybody know how to block websites on Mac? Any help will be greatly appreciated.” From an anonymous Mac user.

There will always be some distractions that prevent you from focusing on the actual task. These distractions can be constantly checking your emails, reading your Facebook feed,watching some funny YouTube videos, listening to online radio, etc. Here are some methods for you about how to block websites on mac. This article falls into four parts listed as below:

Method One: Block Websites on Mac Using Parental Controls

You can use Parental Controls in Mac OS X to help prevent user accounts from accessing to some Internet websites regardless of which Internet browser is used. This part describes how to block websites using Parental Controls step by step.

Step 1. From the Apple menu, choose System Preferences. From the View menu, choose Parental Controls.

Step 2. Select the user account on the left side of the window that you would like to enable parental controls. Then click "Enable Parental Controls". Click the Content tab to set restrictions. If there are no user accounts for you to choose, you’d better set a new one to be enabled Parental Controls by clicking “+” button.

Step 3. Choose “Web” and choose one of the three modes under Website Restrictions. See below for a description of each. Then click the lock to prevent further changes.

Note: Parental Controls cannot be enabled for administrator accounts (admin accounts will not appear in the window). Check Accounts preferences in System Preferences to see which account(s) have what level of access (Admin, Managed, and so forth).

Method Two: Block and Unblock Sites through Hosts File in Terminal

Using Terminal to blocking website on Mac is free for Mac users without buying any application. The process is relatively quick, and requires altering your Mac’s hosts file to redirect a specified domain name. This process will prevent users from seeing content you deem block-worthy across all browsers but that can be reversed should you want to grant access to the sites in the future. Follow below steps to block a website whether you use Google Chrome or other Internet browsers.

Step 1. Open up Terminal in /Applications/Utilities. Type “sudo/bin/cp/etc/hosts/etc/hosts-original”on the Terminal command line to make a backup of the file. Hit Enter and type in your administrative password when prompted.

Step 2. Next, type “sudo nano /etc/hosts” and hit Enter on the Terminal command line to open up your hosts file in a nano box. Enter your administrative password and you’ll see the host database for your computer. Using your down arrow, go to the bottom, right under where it says, "SERVER_IP_ADDRESS localhost", for example “127.0.0.1 localhost”.

Step 3. Edit the hosts file. Type in “SERVER_IP_ADDRESS domain.com”, such as “127.0.0.1 facebook.com”. On a new line, type in “SERVER_IP_ADDRESS www.domain.com”; this is for extra measure. Now, hold down Control + “O”. This will save the changes to the host database. Hit “Return” and then Control + “X” to exit the screen.

Step 4.Remove the existing cache by typing in "sudo dscacheutil -flushcache" in the command line, this refreshes the existing cache on the host database. You should receive an “Unable to connect” error message when you go to the website.

Note: You can also unlock these websites by repeating the steps above but removing the information entered in step 3. This method can be tedious.

Method Three: Blocking Websites on Mac With  a Mac Website Blocker

Using app will be the most convenient way to add apps and websites, no need to change the setting on Mac. For Cisdem AppCrypt, it with easy interface and overall functions, AppCrypt can block websites and app. Also it is very easy to remove the app blocked and add some websites to the blacklist and whitelist.

Method Four: Prevent Access to Websites Using Internet Browser Extensions

Some Internet browsers such as Google Chrome and Mozilla Firefox allow you to download extensions for your browser in which you can manage websites. Go to your Internet search engine and enter keyword phrases such as "Chrome add-ons" or "Firefox extensions" to locate websites that feature add-ons for your particular browser. Then download the extensions and add them to your browsers.
