OS 12.3 on a M1 MBP: how to always Turn on Verbose Booting

[Change Agent]

​

In the good old days of Intel Mac, you entered

sudo nvram boot-args=”-v”


in Terminal and it worked. I tried this on my M1 MBP and it did not work. On the internet I did not find much information. One titbit I found is here: https://eclecticlight.co/2020/11/28/startup-modes-for-m1-macs/
Howard states there: However, this no longer appears to work in macOS 11.2 and later.
However, on my Intel MBP’ with 12.3.1 it works fine.
He also states: You should also be very careful when working with NVRAM settings on an M1 Mac: any errors or problems may require a complete system reinstall, apparently.
Does anybody agree with that in case of activating Verbose Mode?

So, two questions:
1. Is it possible to activate and if so how?
2. Any dangers that anybody is aware of?

Thanks.

I am not sure how to do this but I know that M1 has a totally different way of booting. Nothing you knew from Intel applies anymore to M1.

agreed and i have noticed. Hence the question.

Lot of boot args are filtered by the security boot-up policy, and the "-v" is one of them. You can set it, but it is now filtered by default so that it does nothing(the boot-loader does not pass this arg to the kernel).

You have to use bputil -a in recovery mode's terminal to downgrade the boot security first to allow all boot args.

100% sure?

100% sure?

AFAIK it's the only way.

This how to use the articleHow To:Boot Silicon M1 Macs into Recovery Mode and user the Fiber Menu to use Terminal there and do things!

Thnaks, I knew all that. but it does not adress my question. Or did I miss something?

I wasn't being snaky but you are! Verbose Mode is INTEL only so in M1 era or better you retrain yourself to new chip set! if you don't change you'll be left behind!
