The JSS I inherited has both Managed Preferences and Configuration Profiles that disable the use of Wi-Fi by creating the above PLIST and adding the value {DisableAirPort=true}.
I've been trying to find ways to undo this for a computer that needs access to Wi-Fi, but am not having any success. I'm mainly concerned with the Managed Preference. I first tried just adding the specific computer to the Exclusions for the Managed Preference, and confirmed when I looked at the Computer object that it didn't have any Managed Preferences involved. But I still couldn't enable Wi-Fi.
I next tried creating an inverted Managed Preference (that would set {DisableAirPort=false}) and confirmed that it was listed on the Computer object page, but still couldn't re-enable Wi-Fi on the computer. I tried a few other things but ultimately couldn't find a fix.
My last guess would be to try to manually delete the com.apple.MCXAirport file, but I wasn't able to find it on the computer (in LaunchAgents or LaunchDaemons or Preferences or a few other folders I checked). Does anyone know where this file (or Managed Preferences in general) would be stored on the computer?
