Changing Your MacBook Pro Airport MAC Address in Snow Leopard

Jan 12, 2010 by     3 Comments    Posted under: Mac OS X, Tech

There are several reasons you might want to do this, namely to bypass time-limit restrictions on free WiFi. If that’s your thing, this is for you:

1. Check your current MAC address from Terminal:

ifconfig en1 | grep ether

2. Keep Airport turned on, but log out of all networks (click the Airport icon, “Join Other Network,” enter a bogus one, and hit cancel as it searches).

4. From terminal again, type:

sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport -z

5. Still in terminal, change your MAC address with a command like:

sudo ifconfig en1 ether 00:e2:e3:e4:e5:e6

6. Check your new MAC address to make sure it saved:

ifconfig en1 | grep ether

Done…

    it doesn’t work. I’m on a Macbook pro
    if i change the mac address, I get “Connection Timeout” message everytime i try to join a wireless network.
    If i change back to the original MAC address it works fine again.
