antimac is a fast, gallant MAC address spoofing tool for macOS, written in C.
Inspired by the Millennium Falcon: scrappy, reliable, and always ready to jump to lightspeed.

Features

• Instantly generate and set a random MAC address for any interface
• Show the current MAC address of your device
• Set a specific MAC address of your choosing
• macOS native (arm64 & Intel)
• Requires root for MAC changes (sudo)

Usage

# Set a random MAC address
sudo ./antimac <device>

# Show the current MAC address
./antimac -s <device>
./antimac --show <device>

# Set a specific MAC address
sudo ./antimac -c <device> <new-mac-address>
sudo ./antimac --config <device> <new-mac-address>

# Show version
./antimac -v
./antimac --version

Disambiguation

• anti: instead, in the place of
• mac: MAC address (media access control address) — a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment.

Example

sudo ./antimac en0
./antimac -s en0
sudo ./antimac -c en0 00:11:22:33:44:55
