Changing the contents of a computer’s host file is extremely helpful skill for web developers to have. You can basically manipulate the way your computer looks at the internet. I use it to keep Google Analytics from counting me as a visitor on my site (or any site for that matter). Whatever your reasons for editing your host file, here’s how to do it on a Mac.
1. Open Terminal
2. Type: sudo pico /etc/hosts
3. Type: YourPassword
*This is the same password you use to log in to your computer
4. Edit host file
5. To save your changes hold down CONTROL & press the letter ‘O’. Then press ENTER
6. To exit your host file hold down CONTROL & press the letter ‘X’.
7. To quit Terminal simply hold down COMMAND & press the letter ‘Q’ at the same time.
And that’s it. You’ve just edited your Mac’s host file.
