SpoofMAC - Spoof your MAC address
For OS X, Windows, and Linux (most flavors)
I made this because changing your MAC address in Mac OS X is harder than it should be. The biggest annoyance is that the Wi-Fi card (Airport) needs to be manually disassociated from any connected networks in order for the change to be applied correctly. Doing this manually every time is tedious and lame.
Instead of doing that, just run this Python script and change your MAC address in one command. Now for Windows and Linux, too!
You can install from PyPI using
pip install SpoofMAC easy_install SpoofMAC
or clone/download the repository and install with
git clone git://github.com/feross/SpoofMAC.git cd SpoofMAC python setup.py install
If you're not using the system Python (because you use Homebrew, for example), make sure you add '/usr/local/share/python/' (or equivalent) to your path.
Or, consider using spoof, a node.js port of this package.
SpoofMAC installs a command-line script called
spoof-mac.py. You can always
see up-to-date usage instructions by typing
Some short usage examples.
List available devices:
spoof-mac.py list - "Ethernet" on device "en0" with MAC address 70:56:51:BE:B3:00 - "Wi-Fi" on device "en1" with MAC address 70:56:51:BE:B3:01 currently set to 70:56:51:BE:B3:02 - "Bluetooth PAN" on device "en1"
List available devices, but only those on wifi:
spoof-mac.py list --wifi - "Wi-Fi" on device "en0" with MAC address 70:56:51:BE:B3:6F
Randomize MAC address (requires root)
You can use the hardware port name, such as:
spoof-mac.py randomize wi-fi
or the device name, such as:
spoof-mac.py randomize en0
Set device MAC address to something specific (requires root)
spoof-mac.py set 00:00:00:00:00:00 en0
Reset device to its original MAC address (requires root)
While not always possible (because the original physical MAC isn't
available), you can try setting the MAC address of a device back
to its burned-in address using
spoof-mac.py reset wi-fi
(older versions of OS X may call it "airport" instead of "wi-fi")
Another option to reset your MAC address is to simply restart your computer. OS X doesn't store changes to your MAC address between restarts. If you want to make change your MAC address and have it persist between restarts, read the next section.
Optional: Run automatically at startup
OS X doesn't let you permanently change your MAC address. Every time you restart your computer, your address gets reset back to whatever it was before. Fortunately, SpoofMAC can easily be set to run at startup time so your computer will always have the MAC address you want.
Startup Installation Instructions
First, make sure SpoofMAC is installed. Then, run the following commands in Terminal:
# Download the startup file for launchd curl https://raw.githubusercontent.com/feross/SpoofMAC/master/misc/local.macspoof.plist > local.macspoof.plist # Customize location of `spoof-mac.py` to match your system cat local.macspoof.plist | sed "s|/usr/local/bin/spoof-mac.py|`which spoof-mac.py`|" | tee local.macspoof.plist # Copy file to the OS X launchd folder sudo cp local.macspoof.plist /Library/LaunchDaemons # Set file permissions cd /Library/LaunchDaemons sudo chown root:wheel local.macspoof.plist sudo chmod 0644 local.macspoof.plist
By default, the above will randomize your MAC address on computer startup. You can change the command that gets run at startup by editing the
sudo vim /Library/LaunchDaemons/local.macspoof.plist
