  • Cross-version compatibility: Works on both intel and ARM
  • Automatic Wi-Fi handling: Properly manages Wi-Fi state during MAC changes

Installation

Homebrew (macOS 10.15+)

  1. Install brew (http://brew.sh/)
  2. brew update
  3. brew install acrogenesis/macchanger/macchanger

Manual (no Homebrew)

Homebrew no longer supports macOS 10.14, so Mojave users should install from source:

git clone https://github.com/acrogenesis/macchanger.git
cd macchanger
sudo make install

To uninstall:

sudo make uninstall

This sequence bypasses Apple's restrictions and successfully changes the MAC address.

Supported Interfaces

  • Wi-Fi interfaces (en0, en1): Full support with automatic Wi-Fi management
  • Ethernet interfaces: Direct MAC address changes
  • Other interfaces: Basic support

Troubleshooting

If you encounter issues:

  1. Make sure you run with sudo: The script needs admin privileges
  2. Try again: Sometimes the first attempt may fail
  3. Check your interface: Use ifconfig to verify the correct interface name
  4. Verify the change: Use macchanger -s en0 to confirm the new MAC address
