Change MAC Address – How to Properly Change on MacBook Pro

mac addressmacosterminal

I am unable to change my MAC address using sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx. I was previously able to do it before I completely erased my Mac and reinstalled macOS Catalina.

Does anyone know how to change it and why its not changing? Thanks!

Best Answer

Your command is correct, once you've prepared the network to be changed. Temporarily power down the WiFi before changing the address.

Doesn’t work on newer macbooks (2018 and later)

networksetup -setairportpower en0 off

Modify the mac address with the desired value:

sudo ifconfig en0 ether 88:63:11:11:11:11

Finally, turn on the WiFi

networksetup -setairportpower en0 on

I verified with Catalina 10.15.4 and 10.15.5
