error message for Drupal admin site

Hello:

I keep getting the following error message when I try to log on to the Drupal administrator site. How can I fix his? Thanks.

Unable to connect

Firefox can’t establish a connection to the server at claritza-jimenezs-macbook.local:8080.

• The site could be temporarily unavailable or too busy. Try again in a few
  moments.

• If you are unable to load any pages, check your computer’s network
  connection.

• If your computer or network is protected by a firewall or proxy, make sure
  that Firefox is permitted to access the Web.

Hi,

Have you reboot your machine? Try the following. Open an OS X Terminal and type the following:

$ cd /Applications/drupal-version
$ ./ctlscript.sh start

Then try to access to your Drupal installation in your browser at http://127.0.0.1:8080. I hope it helps.
