This document attempts to explain the Apple Silicon (i.e. M1 and later) Mac boot ecosystem (henceforth “AS Macs“), as it pertains for how open OSes interoperate with the platform.

It is intended for developers and maintainers of Linux, BSD and other OS distributions and boot-related components, as well as users interested in the platform, and its goal is to cover the overall picture without delving into excessive technical detail. Specifics should be left to other wiki pages. It also omits details that only pertain to macOS (such as how kernel extensions work and are loaded).
