We have a script to disable the macOS randomization, it’s been working prior to macOS 15.6.  Since  15.6 it has not worked, it also does not work on the beta of Tahoe.  

The script would hard code the MAC randomization to OFF, and set the default for all new networks to “NOT SET” which then becomes “OFF”.

Has anyone else experienced issues with MAC randomization on 15.6 or the Tahoe beta? 

Is there a reason you’re using a script for this and not a configuration profile? Apple has made this a manageable setting in the Network payload of computer configuration profiles.

is this the one you are using?

 

sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist PrivateMACAddressModeSystemSetting -int 1

This is the answer.  Use a preconfigured profile.  Done and done.

Yes, the goal is to limit the randomization on any network the macbooks join, new and currently saved.  My understanding is the a configuration profile would only work on currently managed networks not new networks as well.  The script is based off of ​@brunerd ‘s script to set the private mac address mode.

 

 

 

​@rstallingsiii Evidence suggest that Apple no longer supports the PrivateMACAddressModeSystemSetting key to globally disable MAC address randomization, much like they’re removing the ability to get the active Wi-Fi SSID via a shell script, and the odds of that working again in the future are pretty slim.

If you’re managing a Wi-Fi configuration via a Configuration Profile Network payload as ​@talkingmoose references then you have still have option to disable MAC address randomization for that network, and that is the only supported (i.e. likely to keep working) way.

Just to jump on the bandwagon, we changed this to a Configuration Profile as well.  More and more items are not manageable via script anymore.  I don’t know if that is good or bad, it just is…   🤓

We use a config profile as well.

If you really want to disable MAC randomization globally, file Feedback and explain why it would be beneficial to your users or organization.

Given that MAC randomization is designed to enhance user privacy, I seriously doubt Apple will ever (re-)enable this.
