  • 1.  MacOS Sequoia - Private Wi-Fi Address on MDM managed networks

    Posted Sep 24, 2024 07:48 PM

    Hi All, 

    Spent today being plagued with support requests from users unable to connect to WiFi after updating to MacOS Sequoia 15.

    Turns out Apple have enabled MAC randomization by default, even for MDM managed WiFi profiles.

    What's new for enterprise in macOS Sequoia - Apple Support

    MDM can configure the use of the hardware MAC address instead of a private MAC address on a managed Wi-Fi network. A privacy warning is shown when using the hardware MAC address because it allows tracking by Wi-Fi networks and nearby Wi-Fi devices.

    This was a problem for us because we have the Intune integration with Clearpass and perform Authorization on the devices MAC address matched to Intune.

    Intune does not yet have a setting in the WiFi template to control the Private WiFi Address option (but does exist for iOS strangely)

    That's annoying. Sounds like a limitation on the InTune side.

    More annoying is that even when Intune (no capital T) adds it for macOS, it can't be deployed to a pre macOS 15 device in advance due to the way configuration profiles work.

    Mac randomization in itself should not be a big issue, unless you base authorization on MAC address. With Intune, the recommended authentication method is certificate based (TEAP or EAP-TLS in case of MACs) and authorization would be based on the certificate information, like Intune DeviceID and/or AAD_DeviceID.

    For monitoring it is still annoying as it's harder to see client behavior across different sessions.
