A Utility to Spoof MAC addresses in OS X?

Question

Is there a menu bar style tool, or maybe a GUI program that would allow me to switch / spoof MAC addresses for the Airport / WiFi connection on OS X?

Solution 1

You really can pass up the GUI interface for this one - it's a one-liner:

sudo ifconfig en1 lladdr aa:bb:cc:dd:ee:ff

If you absolutely want it to be easy, use an apple script so you can click it in your menu bar. This discussion can help with syntax.

tell application "Terminal"
do script "/path/to/script"
end tell

The best reference is here, though there are handy too:

Solution 2

• LinkLiar, free
• WiFiSpoof, paid (was free)

Both menu bar utilities, 10.10+ (LinkLiar had a prefpane ≤10.9, WiFiSpoof used to work also ≤10.9).

I would actually make two apple scripts - one to spoof and one to revert back. This information should set you up to do so.
