    To better decode WebRTC/TURN traffic, the devel and HEAD installs have a
    very hackish patch applied to them.

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

      curl 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

    output = shell_output("#{bin}/capinfos -Tmc capture.pcap")
