Not exactly what you are asking for but we are using something like this when computers get stolen.
Not my script (think it was found here).

#!/bin/sh

INTERFACE=$(networksetup -listallhardwareports | grep -A1 Wi-Fi | tail -1 | awk '{print $2}')

STATUS=$(networksetup -getairportpower $INTERFACE | awk '{print $4}')

if [ $STATUS = "Off" ] ; then

    sleep 5

    networksetup -setairportpower $INTERFACE on

fi



/System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport -s | tail -n +2 | awk '{print substr($0, 34, 17)"$"substr($0, 52, 4)"$"substr($0, 1, 32)}' | sort -t $ -k2,2rn | head -12 > /tmp/gl_ssids.txt



if [ $STATUS = "Off" ] ; then

    networksetup -setairportpower $INTERFACE off

fi



OLD_IFS=$IFS

IFS="$"

URL="https://maps.googleapis.com/maps/api/browserlocation/json?browser=firefox&sensor=false"

exec 5</tmp/gl_ssids.txt

while read -u 5 MAC SS SSID

do

    SSID=`echo $SSID | sed "s/^ *//g" | sed "s/ *$//g" | sed "s/ /%20/g"`

    MAC=`echo $MAC | sed "s/^ *//g" | sed "s/ *$//g"`

    SS=`echo $SS | sed "s/^ *//g" | sed "s/ *$//g"`

    URL+="&wifi=mac:$MAC&ssid:$SSID&ss:$SS"

done

IFS=$OLD_IFS



#echo $URL

curl -s -A "Mozilla" "$URL" > /tmp/gl_coordinates.txt

LAT=`cat /tmp/gl_coordinates.txt | grep "lat" | awk '{print $3}' | tr -d ","`

LONG=`cat /tmp/gl_coordinates.txt | grep "lng" | awk '{print $3}' | tr -d ","`

ACC=`cat /tmp/gl_coordinates.txt | grep "accuracy" | awk '{print $3}' | tr -d ","`

#echo "LAT:  $LAT"

#echo "LONG: $LONG"

#echo "ACC: $ACC"



curl -s -A "Mozilla" "http://maps.googleapis.com/maps/api/geocode/json?latlng=$LAT,$LONG&sensor=false" > /tmp/gl_address.txt

ADDRESS=`cat /tmp/gl_address.txt | grep "formatted_address" | head -1 | awk '{$1=$2=""; print $0}' | sed "s/,$//g" | tr -d " | sed "s/^ *//g"`



#if [ $EA -ne 0 ] ; then

#    echo "<result>$ADDRESS (lat=$LAT, long=$LONG, acc=$ACC)</result>"

#else

    echo "$ADDRESS (lat=$LAT, long=$LONG, acc=$ACC)"

#fi



rm /tmp/gl_ssids.txt /tmp/gl_coordinates.txt /tmp/gl_address.txt

Can you clarify what does this actually do?
Do you deploy it to all Macs as a policy or how exactly do you use it?
Does it need to be tweaked for our own environment in any way?

We just deploy it as a script and then can look in the log for that Policy at any time to see a laptops last reported location.

@HangerS Thanks for the script. really nice!
If we don't use Mozilla, can i just change it to something like Safari?

#echo $URL

curl -s -A "Safari" "$URL" > /tmp/gl_coordinates.txt

Cheers

i have a question about this statment,

if [ $STATUS = "Off" ] ; then
networksetup -setairportpower $INTERFACE off
fi

if you wifi is off then turn it off anyway? am i not reading that correctly?

@peter.caldwell Not my script but you're welcome =)
It should not matter if you use Mozilla or not it should work with original code anyway.

@michelm It basically connects to any open wifi access point or connect to anyone already configured and
fetch coordinates from google and then post them in an echo so you will se where the computer is when policy has ben run.
We are only using this in a "stolen" static group if we loose any computer. But you can ofcource run it on regular basis if you want to track your computers.

@jchurch if wifi was off from the beginning it disables it again when done. So we don't leave an obvious trace that we have tracked the computer.

Tried it. Nice.

Is there an update to this script for Catalina/Big Sur/Monterey? I ran the script on a test computer with Bug Sur and I got some errors. It doesn't recognize the "tr" and "print" commands.
