There is no iwlist on Mac OS, that is why I've created my own script to get all SSID around me via cli ;)

Before running anything, check out the requirements.txt and make sure you have everything neccessary to run this script installed. To install all needed requirements:

pip install -r requirements.txt

Then run a script:

python3 wifi-scan

How to use it:

python3 wifi-scan.py

{'SOME WIFI': {'BSSID': '11:11:11:11:11:11', 'RSSI': -45},
 'ANOTHER_WIFI': {'BSSID': '11:11:11:11:11:11', 'RSSI': -57}}

Wifi-scan.py support filter argument, which can be used to find any particular SSID.

python3 wifi-scan.py -f SOME_WIFI

{'SOME WIFI': {'BSSID': '11:11:11:11:11:11', 'RSSI': -45}
