      If your list of available capture interfaces is empty
      (default OS X behavior), try the following commands:

        wget https://bugs.wireshark.org/bugzilla/attachment.cgi?id=3373 -O ChmodBPF.tar.gz
        tar zxvf ChmodBPF.tar.gz
        open ChmodBPF/Install\\ ChmodBPF.app

      This adds a launch daemon that changes the permissions of your BPF
      devices so that all users in the 'admin' group - all users with
      'Allow user to administer this computer' turned on - have both read
      and write access to those devices.

      See bug report:
        https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=3760
