    What on earth is the point of randomising a MAC address on a wired connection? The randomisation is to prevent unknown & therefore untrusted public wifi connections from tracking you. It makes no sense whatsoever otherwise [& should also be switched off for known-trusted connections on WiFi too].

  • I dont know or care how you would do mac spoofing on an Apple orWindows box, but the hardware is definately capable of tjis. Its trivial under Linux.

  • There are several tools allowing you to do that (at least on Windows).

    @Tetsujin Thanks for informing me of that. I had no idea. I just assumed it would be beneficial on all devices wired and wireless.

  • No. MAC address doesn't traverse borders, so on a wired connection it never leaves the building. On public wifi a fixed MAC could be used to track your connection habits - do you go to Starbucks every day, or sometimes get Pret instead. In a domestic or even business network, that's just not an issue.
