Hello.

I'm not sure if this is a Firewalla issue or Apple here, but in iOS18, there is this new option "Rotate Wifi Address" which replaces the private mac address option.

However, even when deactivating it, Firewalla always reports these devices as using MAC randomization. I could see that as being an issue when using guest networks with portals that would not allow MAC randomization.

Is that something you are aware of ? Maybe I missed some setup in iOS18...

  We can't comment on Apple's beta's, since they do change pretty often.

  My understanding is, at home, you are at a trusted network, and you really don't need to rotate MAC or generate private MAC's. (This is true for enterprise as well). 

  Do you see an option to disable Rotate WiFi/Randomize WiFi?

  As i said, there is an option to deactivate, but it still appears as randomised Mac in devices. Maybe a bug on Apple side

  I have 3 devices on iOS 18 and a MacBook on 15.0. All devices have Mac address randomization turned off.

  * 2 iPhones on 18.1 (22B5007p) - works fine

  * Macbook on 15.0 (24A5298h) - works fine

  * iPad on 18.0 (22A5316k) - appears as randomized in Firewalla

  I agree that it feels like it's an Apple bug -- maybe an issue with the early 18.0 builds.

  This is still occurring with the prod release of iOS 18. It's only happening on one of my devices though
