Sometimes we want to do things that require us to change the MAC address associated with our networking device. Say, get on a network that’s filtered by MAC addresses, or, add an extra level of anonymity when you’re on an open wireless network.
It’s pretty simple. Open up the terminal. Type:
ifconfig en1: for your wireless device, or
ifconfig en0: for your wired device.
This will give you your default MAC address. Make sure to copy it down, and save it somewhere so you can chance it back when you want to.
Now to change the MAC address on your wireless card type:
sudo ifconfig en1 ether aa:bb:cc:dd:ee:ff
Enter your password and you’re done. Now, a side note here is that the aa:bb:cc:dd:ee:ff has to be between 0-9, and a-f. So, for instance, a1:b2:c3:d4:e5:f6 would work. m4:1z:3d:l5:az:K6 would not!
Now if I could only change my wireless modes I’d be set!
