How to block a website on a Mac:

Launch “Terminal” by going in /Applications/Utilities.
When prompted, in the command line, type in "sudo nano /etc/hosts".
It will then ask for your admin password, type your admin password.
Next you’ll see in the screen the host database for your computer.
Use the down arrow to go to the bottom and below under where it states, "127.0.0.1 localhost".
Type in "127.0.0.1 facebook.com".
On the next line type "127.0.0.1 www.facebook.com"; just to be safe it’s working correctly.
Next, hold down Control + “O”, which will save the changes to the host database.
Press the “Return” key and then followed by Control + “X” to exit the current screen on your Mac.
You can remove the past cache on your Mac by typing in "sudo dscacheutil -flushcache" in the command line, this refreshes the existing cache on the host database.
Test to make sure it works by going to Facebook.com, when you go to the site a message saying, “Unable to connect” error message will show up and blocking you from going to the Facebook site.
