    This formula only installs the command-line utilities by default.

    Install Wireshark.app with Homebrew Cask:
      brew cask install wireshark

    If your list of available capture interfaces is empty
    (default macOS behavior), install ChmodBPF:
      brew cask install wireshark-chmodbpf
