I just found this and it worked on my 2023 MacBook Pro M2 Pro running Ventura 13.4.1: From: Github link Change MAC Address in macOS Monterey I was unable to change the MAC address of the Wi-FI device on a MacBook Air (M1 2020) running macOS Monterey due to the following error: ifconfig: ioctl (SIOCAIFADDR): Can't assign requested addres. By running these commands in following sequence I was able to change it successfully: Turn WiFi device off: Click the Wifi icon in the menu bar and toggle the switch. Turn the WiFi device on again: networksetup -setairportpower en0 on Change the MAC: ifconfig en0 ether <new mac-address-here> Run: networksetup -detectnewhardware The changed MAC address is not reflected anywhere in the GUI, but if you do an ifconfig en0 from Terminal it shows there. And of course it will reset back to the hardware MAC address when rebooted.
