How to edit your hosts file on a mac
(If you need to make a hosts file modification in Windows, please see our Modifying Your Hosts File article instead.)
Like many Unix-based and Unix-like operating systems, it is possible to change the hosts file on your Mac to manually set a domain to a certain server.
Changing this file will override any DNS settings you might receive from your ISP, so this is a good way to test a site before you have transferred the domain from your old host to us.
Modifying the hosts file in Mac OS X 10.2 and later is a pretty easy task, but it must be done as the “root” user in the terminal. This change will point ONLY your Mac to your site with us. It will not affect other computers' access to your site at your former host.
Below are the five easy steps you'll need to take.
- Open the Mac's Terminal.
- Open the hosts file for editing.
- Edit the hosts file by adding these two lines to the bottom of the file.
- Save save your changes by pressing control-o on your keyboard then return to accept the filename. Exit the editor by pressing control-x. This takes you back to the terminal screen.
- You may need to flush your Mac's DNS cache, so copy/paste the below command string into terminal, and press return.
You may either type Terminal on the Spotlight, or by going into Applications -> Utilities -> Terminal.
In the terminal window you just opened copy/paste the command string below, and press return.
sudo nano /private/etc/hosts
You'll be prompted to enter your Mac user's password. NOTE: you won't see the cursor move. This is normal, so press return when done.
For example, it should look like:
Make sure that there is a space between the IP and the URL! Otherwise, the rule will not work.
Be sure to place domain.com with your actual domain name. If you're not sure which IP address to use, please contact our Support Department for further assistance.
This completes the hosts file modification, so you should now be able to see your site here with us using your domain in your browser's address bar.
When testing is complete you may undo these changes by repeating the steps above but removing the information entered in step 3.
If you are running a Windows based system, please see our general hosts file article.

In step #4 when I press control-x nothing happens, so I cannot clear my cache per step 5.

Within the nano text editor, ctrl+x will indeed quit the exitor that is running inside the terminal window. Be sure that you are pressing ctrl+x and not command+x.

I am stuck on step 4 as well. I pushed both control-x and control+x and it wont go back. So I'm not sure it saved.

I tried the control (+/=) bottom and c. And still do nothing. I guess what should i be looking for because All i'm seeing is the host database.

Based on your reply, it sounds like you're trying to press 3 different buttons at one. To clarify, press the control and c buttons at the same time, and not any additional keys.
