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

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

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