How to change the MacBook Pro login screen at startup?
There is a login screen that only appears after powering up my 16 inch 2021 MacBook Pro from a powered-off state. I strongly dislike the image and I'd like to change it to something else. Unfortunately, I cannot figure out how to do this. The answer seems to change for every macOS version and I have yet to find instructions for Monterrey.
To be clear, I'm not talking about the initial display of the white apple on the black screen, and I'm not talking about the login screen that appears after a restart. I'm talking about the login screen that only appears after powering up from a shutdown.
Anyone? Thanks.
