Spoofing MAC address on 10.5.6

[YFK2009]

Hi there.

I'm trying to spoof my MAC address, using 10.5.6 (intel imac) and connecting via wired ethernet.

I've been googling this for a while to no avail... seemingly it was possible on earlier versions of OSX but maybe not 10.5...

Can anybody help?

Does this command not work anymore:

ifconfig eth0 down hw ether 00:00:00:00:00:01

ifconfig eth0 up

Simply put the Mac address that you want to use instead the one above

Use Backtrack 4 beta

Really, cuz I did one search from Google and came up with:

The interface needs to be up in OS X to change the MAC address.

The command is :

sudo ifconfig enx ether xx:xx:xx:xx:xx:xx

I'm not sure whether you're calling me a liar or an idiot. I've googled (as I said) and read all the articles I found, to no avail.

That article you linked to tells you how to spoof WIRELESS connections, and the steps suggested (including in the comments) do not work for a wired connection on 10.5.6.

Yes do this. Just know that spoofing your MAC addy only works with the Airport card (en1). It does not work with ethernet (en0).

Really? When I Google'd this the other day people were saying the opposite, and that if you try and change the airport MAC address that it will mess things up

Please see first post - I want to do it with ethernet!

Use Backtrack 4 beta

Can it be run on OSX or is it Linux only?

Whether spoofing works or not depending on the exact hardware in your Mac.

Spoofing it doesn't mess up your computer in any way. The address will revert to its' default after a reboot.

YFK: If you start up in Backtrack, it will only spoof the MAC address while Backtrack is running. It won't persist after the reboot. I think.

none of te methods work for me really, I'm on macook pro alluminum and trying to change ethernets mac address, still no solution anywhere really

tells me permission denied when I enter ifconfig en0 down hw ether, which is strange as I'm on administrator account

Like I said earlier, this will only work using your AirPort connection.

Guys, it is related to OSX version and drivers and the type of hardware you have. i honestly have no idea why Apple did this but those commands won't work for most people on leopard running the recent models.

You need to add sudo in front of the command to run it as the root user.

e.g.

sudo ifconfig en0 down hw ether

 

[sMiK]

i enter sudo ifconfig en0 down hw ether 00:18:F35:716
it asks for a password but it says ifconfig: hw: bad value

 

[Jethryn Freyman]

The command you entered is shutting down the interface. Make sure it is online, and enter:

sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx

 

[sMiK]

by saying online you mean active? it is activated but the thing is when i plug in the cable nothing happens as my provider tied it to my desktop mac address... so what I'm doing wrong?

To bring up an interface:

sudo ifconfig en0 up

To take it down:

sudo ifconfig en1 down
