CONSULTING CONCEPTS PERSONAL not loading on my macbook, mountain lion

December 13th, 2012

This is to share a solution to a problem that may affect Macbook users using Mountain Lion OS X and having problems loading

Two days ago, I suddenly found that I couldn't load and ONLY I would get a timeout error trying to reach Facebook. Attempts to reach (without the www) won't work since redirects to All other sites worked fine. I have a Macbook Pro, using Mountain Lion OSX 10.8.

I tried every solution I could find on the net:

  1. Cleared browser caches
  2. Flushed the DNS on my MAC (you have to use a new command line: "sudo killall -HUP mDNSResponder")
  3. Disabled IPv6
  4. Reduced MTU down to 1300 manually
  5. Attempted to go to enable SSL via
  6. Attempted to change DNS servers, using Google's Open DNS servers (

Nothing worked.

Other symptoms included, not working on multiple browsers (indicated computer or your network problem, not just browser problem), works on other computers on the same network and same problem on different wi-fi network (indicates a problem with my computer).

Finally, I found the solution: For some reason, and was added to my HOSTS file with an IP address that wasn't resolving. The HOSTS file was telling my computer that was located at this specific IP address, bypassing any available DNS servers. As a result, my computer was trying to find at an IP address that wasn't working, ALWAYS.

Here's what you need to do to fix this:

  1. Start Terminal
  2. Type "sudo nano /private/etc/hosts"
  3. Remove any lines with facebook in it. (Mine had two lines for and Don't see any? Then this unfortunately is probably not the reason you can't use Facebook)
  4. When finished, hit Control+O followed by ENTER/RETURN to save changes to /private/etc/hosts, then hit Control+X to exit out of nano
  5. Exit Terminal
  6. Finally, restart your computer to let the changes take place.

Your computer should now load properly! Let me know if that helped, and if anyone knows why these lines suddenly appeared in the HOSTS file, post it here.
