MAC address randomization by removing the ability to read the hardware mac

That was not the idea and this is not a solution.
Modify for example the ART partition and be careful to not remove the calibration data would be probably something that apply to point a) i mentioned above.
There is not a single person who did this? Because there are few people searching for such a solution but not knowing that it can be achieved that way.
For example a discussion with you here: Can somebody help me with script (MAC generator)? - #42 by tor_hider
