I need to pull a report of all MAC addresses for the computers in my environment and the built-in reporting only can display the Primary MAC address. From other posts it seems the only way is with Extension Attributes but the few scripts I've found (https://community.jamf.com/t5/jamf-pro/how-to-customize-what-gets-inventory-for-primary-mac-address-and/m-p/193541#M182332) don't return any results when creating extension attributes. Does anyone have any ideas on how I can grab this info?
Thanks!

Correct, those are the only considerations. Unfortunately none of those commands are returning any results when made into extension attributes. Is there something else I should be inputting along with your commands to make them work?
For any EA to report a value back to the JSS, the output has to be enclosed in "<result></result>" tags.
So:
#!/bin/bash
result=$(/usr/sbin/networksetup -getmacaddress en0 | awk '/Address:/ { print $5 " " $3 " " }' | tr -d '()')
printf "<result>$result</result>"
The shebang says this is a bash script.
'result' defines the value of the newly declared variable with the results of the commands contained within $().
'printf' is often better for multi-line output, but an 'echo' is more typical. '$result' means display the value of that variable.
If you're just starting with EAs, check out Jamf's training entries.
+16The really bare bones result:
#!/bin/bash
result=$(/usr/sbin/networksetup -listallhardwareports | awk '/Address:/ { print $NF }')
echo "<result>$result</result>"
Note that this approach doesn't consider whether an interface is active (connected) or not; consider your use case for gathering this info. Could probably also be improved with a `printf` instead but this was off the top of my head.

Thanks for this! However, I see it populates with what looks like 7 MAC addresses instead of the 2 I was expecting. I don't suppose there's a way to filter to just the 2 Network adapters? It looks like the 1st and 4th MAC addresses are what I need...

Assuming you're only considering en0 and en1, you could simply run:
networksetup -getmacaddress en0
networksetup -getmacaddress en1
Maybe clean up the output a bit with:
networksetup -getmacaddress en0 | awk '/Address:/ { print $5 " " $3 " " }' | tr -d '()'Assuming you're only considering en0 and en1, you could simply run:

This is exactly what I needed, thank you so much! I added your script to 1 EA then copied and changed to en1 with another and now both MAC addresses are displayed. I am in fact just getting started with EAs (in case it wasn't painfully obvious) so I will definitely check out the training on them. Thanks again and have a great rest of your day!
