I don't mind the notch on the iPhone, but I really dislike the notch on the MacBook. So...
Settings, Displays, show all resolutions,
change from 1470*956(Default) to 1470*918
and the notch is gone, semi-permanently, no need to change wallpapers or whatever.
yeah, you lose a weensie bit of screen but you now have a full unsullied menu bar.
