    If your list of available capture interfaces is empty
    (default macOS behavior), try installing ChmodBPF from homebrew cask:

      brew cask install wireshark-chmodbpf

    This creates an 'access_bpf' group and adds a launch daemon that changes the
    permissions of your BPF devices so that all users in that group have both
    read and write access to those devices.

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