Go to my System Preferences.app and open “Sharing” pane. Disabling the Web-Sharing service.
Launch Terminal.app and stopping httpd (apache) with the following command:
sudo apachectl -k stop
Going into the Activity Monitor.app and searching for “httpd”. Select both processes and click on “Stop”.
Shutdown and start my Mac (do a proper shutdown, not restart!)
When Mac was back up running: go in to Terminal.app and execute:
sudo apachectl -k start
