Description of issue

I tried to run the command

sudo spoof-mac set xx:xx:xx:xx:xx:xx en0

where en0 is my Wi-Fi interface. xx:xx:xx:xx:xx:xx is the MAC address of the Wi-Fi interface of an Xbox which we are trying to get onto a Wi-Fi network requiring authentication through a captive portal. Somehow, the Xbox cannot handle that captive portal, which is why the idea was to try to get the Mac to spoof the MAC address of the Xbox, pose as it, get authenticated, and then go back to its real MAC address through a reboot. Hopefully, that would subsequently allow the Xbox to be accepted onto the network.

However, the output of the above command is

Is this something that can be fixed?

Is this something that can be fixed?

You'll have to ask the spoof-mac developers. The error message you showed looks like a problem with spoof-mac, not Homebrew.
