Why can’t I macchange my 2014 macbook with ubuntu 23.10 on it?

I followed all steps: I disabled network manager’s automatic search for networks with sudo systemctl disable NetworkManager.service, I executed sudo ip link set wlp4s0 down as well, sudo macchanger -r wlp4s0 returned [ERROR] Could not change MAC: interface up or insufficient permissions

this is a 2014 macbook pro 11.1 I used to install ubuntu 23.10 on. If I execute macchanger -l I see a list of vendors and the 6 first digits of the mac address reserved to each vendor, including apple. Is this the reason? But how could it be? Im not running macOS, but ubuntu (macOS hasn’t been completely wiped out of the computer, it’s on a different partition).

Can it be a driver issue? Some drivers don’t support changing the MAC.
