I have only tested this script on OS X 10.6.8, meaning: I have no idea if it works in other versions of OS X. For the most part, it should work without any issues – or worst case scenario: with minor modifications to this script.
This script automates the following process:
1. Identify current MAC Address
2. Generate a random MAC Address (for spoofing/changing)
3. Disconnect/Disassociate Interface
4. Change existing MAC Address with randomly generated MAC Address
5. Power up device/interface
Be sure to change the INTERFACE variable to suit your needs.
Here it is:
#!/bin/bash # Change your network inteface ID here network interface here INTERFACE=en1 ORIGINAL_MAC=`ifconfig $INTERFACE | grep ether | cut -d' ' -f2` MAC=`openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//'` echo "Intial status:" sudo ifconfig $INTERFACE DISCONNECT_NETWORK="sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -z" echo "Disconnect from current network" eval $DISCONNECT_NETWORK sleep 2 echo "Changing interface mac" sudo ifconfig $INTERFACE lladdr $MAC sleep 2 echo "Shutting down interface: $INTERFACE" sudo ifconfig $INTERFACE down sleep 2 echo "Starting up interface: $INTERFACE" sudo ifconfig $INTERFACE up sleep 2 echo "MAC changed from: $ORIGINAL_MAC to: $MAC" echo "Retrieving new network status:" sleep 10 ifconfig $INTERFACE
Having trouble?
If the above method does not work for any reason, try the following:
sudo airport -z sudo ifconfig en1 ether c9:b2:5e:85:b2:dd sudo ifconfig en1 ether
*change c9:b2:5e:85:b2:dd to anything you want
If you have a different version of OS X and have successfully ran a modified version of this script, please let me know.
Thanks.
