You will get a prompt - "scutil is trying to modify the system network configuration. Touch ID or enter your password to allow this."

  1. Computer Name: The user-friendly name displayed on the Sharing preference pane and used for identifying your Mac on a local network.
  2. Localhost Name: The name that is displayed at the bottom of the Sharing Settings window
