Auto-changing MAC address on reboot to a random one.

List of files:

• setup.sh - script for automating the process
  
• macchanger.sh - changing MAC address script
  
• local.macchanger.plist - XML configuration for launchd
  

What is launchd? - a unified, open-source service management framework for starting, stopping and managing daemons, applications, processes, and scripts. More info on launchd.info

chmod +x setup.sh
sudo ./setup.sh

sudo rm /usr/local/bin/macchanger.sh
sudo rm /Library/LaunchDaemons/local.macchanger.plist

The easiest way to change your mac after installing the script in a manual way is creating alias, so:

echo "alias changemac='sudo /usr/local/bin/macchanger.sh'" >> ~/.zshrc
source ~/.zshrc

Change ~/.zshrc to ~/.bashrc if you use bash.
Thus you can you changemac command to run the script.

echo "alias showmac='ifconfig en0 | awk '/ether/{print $2}' | xargs'" >> ~/.zshrc
source ~/.zshrc

Change ~/.zshrc to ~/.bashrc if you use bash.
showmac command shows current MAC address.

Open mind, open heart, open source.
