Interesting! Especially given we have an automated test about this. Perhaps something different happens for Wi-Fi devices? E.g. could it be NetworkManager’s MAC address randomization while scanning for networks?

According to my test, that’s exactly it, and it’s expected since Tails 3.0.

Dear sajolida, please try this:

  1. Start Tails 4.0~beta1
  2. Disable MAC spoofing in Tails Greeter.
  3. Start Tails.
  4. macchanger -s wlan0 → you get a different “Current MAC” and “Permanent MAC”, as expected (for details, see commit:30dd0e10a0f58cd6d6e6a5e859ca52c5b2ecdefe and Feature #11856)
  5. Connect to a Wi-Fi network
  6. macchanger -s wlan0 → you should get “Current MAC” == “Permanent MAC”; if you get different MAC addresses at this point, then it’s a bug and I’ll need a WhisperBack report to investigate further as I can’t reproduce it; if you get identical MAC addresses at this point, then it’s a feature, and please close this ticket as not-a-bug (Rejected)

Thanks in advance!

Indeed, sorry for the noise: the MAC address gets back the the permanent one. Case closed.
