# A script to replicate the previous functionality provided by Apple's former 
# /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport
# tool which was deprected in macOS 14.4. This script uses the /usr/sbin/system_profiler tool.
# This script takes the output and reformats it to reproduce the WiFi SSID report of the former
# airport tool. Due to some differences in capabilities of system_profiler some information is
# not possible to produce and these fields are left empty or with fake data. These fields being
# BSSID, HT and CC but are fortunately less important.
