Simply run “spoof-mac set 00:00:00:00:00:00 en0″ to change your MAC address to anything you want. It automatically handles all the “airport -z” funny business for you.

Get it here: https://github.com/feross/SpoofMAC

it gives error

ifconfig: ioctl (SIOCAIFADDR): Invalid argument

but 00:00:00:00:00:00 works

what do?

Now go to your Mac and follow these steps:

^^^^^^^^^^^^^^^^^^^^^^^^^^
John C.

Here’s my simplified version:

ifconfig en1 | grep ether
^^^ Check Current Mac Address

sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -z
^^^ Disconnect from Networks

sudo ifconfig en1 ether 00:00:00:00:00:00
^^^ Set New Mac Address – FILL IN THE NUMBERS YOU WROTE DOWN.

ifconfig en1 | grep ether
^^^ Check Current Mac Address

^^^^^^^^^^^^^^^^^^

If the ifconfig shows you exactly the numbers you filled in, you are finished.

As long as you don’t shut down your Mac, it will look for the network, as you are your fathers PC/Mac.
You should being able to have now internet access all the time.

I hope i’m right, you can do this also with the MAC-Adress of your siblings.
If you want to figure the MAC-Adress on a Windows-PC just open “cmd” and enter “ipconfig /all”. Now have a look for the “physical adress”.

I am running 10.6.8 if that means anything.

Can you help me?

Thanx a lot!
