      You may also wish to install tuntap:

        The TunTap project provides kernel extensions for macOS that allow
        creation of virtual network interfaces.

        https://tuntaposx.sourceforge.io/

      You can install tuntap with homebrew using brew install tuntap

      Unless it exists already, a aiccu.conf file has been written to:
        #{etc}/aiccu.conf

      Protect this file as it will contain your credentials.

      The 'aiccu' command will load this file by default unless told to use
      a different one.
