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

ifconfig

Output:

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384

    options=3<RXCSUM,TXCSUM>

    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 

    inet 127.0.0.1 netmask 0xff000000

    inet 192.168.1.105 netmask 0xffffff00 broadcast 192.168.1.255

    media: autoselect

    status: active

sudo ifconfig en1 lladdr B2:E6:1C:0B:C7:C9

sudo ifconfig en1 down

sudo ifconfig en1 up

ifcongig

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?
