Does Tails spoof Mac?
When MAC address anonymization is enabled, Tails temporarily changes the MAC addresses of your network interfaces to random values for the time of your Tails session. MAC address anonymization hides the serial number of your network interface, and so, to some extent, who you are, from the local network.
Does Tails work on Mac M1?
Tails does not work with Mac models that use the Apple M1 or M2 chips. Tails does not work on 32-bit computers since Tails 3.0 (June 2017).
Does Tails hide your IP address?
During my tests, I found that connecting to the internet with Tails doesn't hide you completely. Your ISP can't see what you're doing, but when you connect it can see that you're using Tails (and Tor).
