In short, upgrading macOS can have negative affects as it can change things in the EFI partition afaik. I'm not one of our M1/2 experts, but from my own experience using OpenBSD on my systems is I think we use device information and firmware from the system/EFI partition. (I'm sure a dev will correct me if I'm wrong here.) So, tl;dr: it's not safe to blindly run macOS updates. It's been known to cause havoc with Asahi and OpenBSD because of how it changes things we were depending on. -dv
