What happens when an M1 Mac starts up? – The Eclectic Light Company:

You can learn a great deal from the unified log entries of a system startup, and that for an M1 Mac is even more fascinating for the insights it gives into the hardware in the M1 system-on-a-chip (SoC). These were obtained from an M1 MacBook Pro with 8 CPU cores and 8 GPU cores running macOS 11.0.1 fairly clean, and in full Secure Boot.

I always liked low level stuff in computers. I learned 6502 assembly language (if we can call this a “language”) when I was a teenager. If you’re into these type of things, it is a fascinating short read that opens the door to what is going on in your M1 Mac.
