Thanks for the quick response. I was able to find the pkg and install it. Can I ask why I can’t deploy it with JAMF to my user base? I use the script to set Wireless network orders and it was recently updated to use pyton3 from MacAdmins.

That said, you can download the latest pkg from the releases page on macadmins/python and just double-click to install locally, though it's meant to be deployed to a user base with JAMF or another tool. Once it's installed, add the shebang that leads to the install to any scripts you deploy and it will use that version of Python to run the script. — Reply to this email directly, view it on GitHub<https://urldefense.proofpoint.com/v2/url?u=https-3A__gist.github.com_fcbdd3924ee230592ab4-23gistcomment-2D4126048&d=DwMCaQ&c=wcMRSsyWyu-9n0XIzZfY3g&r=8Qg_ffIw3GBedWS7u9ms5usMm2DfUKi8laVIc7_ugoY&m=YbKRzEcPSoeW8i7I00rJvHu5X3PHDAl8oqgBXZM9RV2VeINvdEHlpOquQRYBpkn7&s=-d53ndYQGhhuS8Im5_sZv43eqGRHxZXLJgZjYSSShto&e=>, or unsubscribe<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_notifications_unsubscribe-2Dauth_AKPW5S6PPA4JIBJJDQX6F6LVEAWT5ANCNFSM44DFVDSA&d=DwMCaQ&c=wcMRSsyWyu-9n0XIzZfY3g&r=8Qg_ffIw3GBedWS7u9ms5usMm2DfUKi8laVIc7_ugoY&m=YbKRzEcPSoeW8i7I00rJvHu5X3PHDAl8oqgBXZM9RV2VeINvdEHlpOquQRYBpkn7&s=OgaIYaiiiO9PiUrrpgBGIrjILqCJDk3WYd0wI758xnY&e=>.

@jleomcdo you can absolutely do that, it's exactly what we're doing at my org.

Is there any script for monterey?

Is there any script for monterey?

The script @skoobasteeve posted a couple comments above works in Monterey, but requires the MacAdmins python3 package to be installed as Monterey doesn't have a default python installed. It works fine on all of our machines in our environment, including the ones running Monterey.

Push the macadmins/python package to your machines. Once it's installed, you can run any Python3 script from JAMF by using a shebang at the top of the script that points to the new instance of Python:

Oh now i get it - thanks so much for your help 👍

Im trying this on Ventura. Installed python3 "python_recommended_signed-3.10.2.80694.pkg" when i run it im getting

Traceback (most recent call last):
File "/tmp/test2.py", line 18, in
CoreWLAN = load_objc_framework('CoreWLAN')
File "/tmp/test2.py", line 15, in load_objc_framework
return collections.namedtuple('AttributedFramework', loaded_classes.keys())(**loaded_classes)
File "/Library/ManagedFrameworks/Python/Python3.framework/Versions/3.10/lib/python3.10/collections/init.py", line 373, in namedtuple
raise ValueError('Type names and field names must be valid '
ValueError: Type names and field names must be valid identifiers: 'Foundation.__JSONDecoder'

@Tkimpton I think I got it working by adding a line to the load_objc_framework() function:

def load_objc_framework(framework_name):
    # Utility function that loads a Framework bundle and creates a namedtuple where the attributes are the loaded classes from the Framework bundle
    loaded_classes = dict()
    framework_bundle = objc.loadBundle(framework_name, bundle_path=os.path.dirname(ctypes.util.find_library(framework_name)), module_globals=loaded_classes)
    # ADDED FOR PYTHON 3 CHANGE
    # Avoids loading libraries that start with an underscore or reference a class e.g. Foundation.xx.
    loaded_classes = dict(x for x in loaded_classes.items() if (not x[0].startswith('_')))
    loaded_classes = dict(x for x in loaded_classes.items() if ('.' not in x[0]))
    # print(loaded_classes_clean.keys())
    return collections.namedtuple('AttributedFramework', loaded_classes.keys())(**loaded_classes)

The error occurs because namedtuple doesn't like class references in a list of strings, and there were keys in the loaded_classes dict with names like Foundation.xx and Swift.xx. I just removed all the items with keys that had a . character in them.

Can you try it and see if it resolves the issue?

@skoobasteeve Works fine on Ventura here! Thank you
See further down

@jstaubr (CC: @skoobasteeve )
How did you manage to make it work on Ventura?
It works great on Monterey but on Ventura there were no change in the Preferred Network's list as I tested.
(It seems they deprecated the function. There's no UI either at System Preferences/Wi-Fi's to change the order of the networks. Only "Known Networks" window. )

Has anybody found a workaround for that?

@daydreamheart I'm sorry to inform you that Apple has "automated" the preferred wifi SSID choice in Ventura. It's not likely this will work going forward.https://support.apple.com/en-us/HT202831

@daydreamheart

Unfortunately @franton is right. I thought it was working because I was on the same network that I tried to make preferred and my CLI check returned the correct SSID.
I found out later last week that Ventura always returns the currently connected SSID as top of the preferred list via
networksetup -listpreferredwirelessnetworks en0

Well it was good while it lasted! At least in their new system they indicate that EAP networks get priority over WPA. Just wish we could retain some control.

Maybe some feedback to Apple is in order?
