I'm trying to change the MAC address for the interface en1.
ifconfig
Output:

It can be seen that the address has changed. But if you go to "System Preferences / Network / Wi-Fi / Advanced / Hardware" there appears an old MAC address 1c:3b:d6:d6:3a:25. And also enabled on the router Wireless MAC Filter is not allow to go network with the old address. Which means that the address is not changed. Any solution?
