Just installed Nixos 22.11 on an old Intell Macbook Air (I think mid-2012) I had, and I have no clue why this is happening. It appears after (~30secs) or so when I boot up the machine.
I installed Nixos from an ISO based on the minimal iso image following this Installing NixOS on a MacBook Pro so it can include the proper wifi drivers.
This is the full `configuration.nix` file

It âseemsâ like everything is working fine though.
