Collect information about SSID on iMac running BigSur via extension attribute

[jamflund]

Hi!

Has anyone managed to get information about the iMac computer's SSID running MacOS BigSur via extensions attribute. If so, how did you do it?

Regards

Hello,
This is what I have been using to get this information, it works on both M1 and Intel macs as well as all MacOS versions.

#!/bin/sh

##Get the wireless port ID
WirelessPort=$(networksetup -listallhardwareports | awk '/Wi-Fi|AirPort/{getline; print $NF}')

##Collect new preferred wireless network inventory and send back to the JSS
PreferredNetworks=$(networksetup -listpreferredwirelessnetworks "$WirelessPort" | sed 's/^   //g')

echo "<result>$PreferredNetworks</result>"

The results look like this

Preferred networks on en1:
Wireless1
Wireless2

Big thanks for sharing your script. Do you or someone else have any a clue how to to send back to JSS current wireless SSID which Mac use at the moment ?

Here's the script that we use for the current SSID connected to:

#!/bin/sh
# Jamf Extension attribute to return SSID

result=`/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I | awk '/ SSID/ {print substr($0, index($0, $2))}'`
echo "<result>$result</result>"

I confirm that it also works on iMac and MacBook with BigSur. Wonderful people - thanks.
