FreeBSD - MacBook Wayland only setup

I decided to revive my old Macbook 4,1 (or early 2008 / A1181) and FreeBSD seemed like a good fit. In addition I wanted to see if I could achieve a Wayland-only setup I could use easily, knowing that my activities are mostly web browsing and shell. The first thing was to get a booting install media, I had to use a 12.2 USB image as I couldn’t go past the loading kernel step on 13.
