# NAME
# enableFilewall.sh -- Enables or Disables the firewall on macOS.
#
# SYNOPSIS
# sudo enableFirewall.sh
# sudo enableFirewall.sh <mountPoint> <computerName> <currentUsername> <enableFirewall>
#
# If there is a hardcoded value specified for <enableFirewall> in the script,
# or if the parameter is not passed by Jamf Pro, the hardcoded value in the script will
# be used.
#
# The data that is specified for the <enableFirewall> parameter should be specified in one of
# the following formats. PLEASE NOTE these formats are CASE-SENSITIVE:
#
# "TRUE" or "true" or "YES" or "yes" -> Turn Firewall ON
# "FALSE" or "false" or "NO" or "no" -> Turn Firewall OFF
#
# Example Usage: sudo enableFirewall.sh "mountPoint" "computerName" "currentUsername" "TRUE"
#
# DESCRIPTION
# This script enables or disables the firewall on macOS 10.7 or later.
# It can be used with a hardcoded value in the script, or read in as a parameter.
# Since Jamf Pro defines the first three parameters as (1) Mount Point, (2) Computer
# Name and (3) Username, we are using the fourth parameter ($4) as the passable parameter to
# acquire the status of <enableFirewall>. In addition, the fourth parameter is utilized to set
# the enableFirewall value.
