M1 Silicon Triage No Go

[Do It All Computers]

I just realized that my Triage Drive will not work with the Mac Mini M1 silicon. I was wanting to install Big Sur, as opposed to the Monterey that auto installs and it will not even see my installers. Anyone have similar issues? Any work arounds?

Maybe it's this: "Security settings do not allow this Mac to use an external startup disk"

That's what I get with my bootable USB Big Sur installer on a recent generation Intel MacBook Pro. My 2015 MacBook Pro seems OK with it. Less luck with my M1. Need to investigate some more.

Greetings @Do It All Computers,

regarding M1 MacBooks you can't use the same installers or liveOS from the intel version, you will have to download the macOS installer on an M1 computer and create a bootable external drive to install/liveOS in M1 chips
