Can not disable SIP on my new Mac mini M1

[vwlinkan]

As I now are completely dependent on Xtrafinder, I want to install it on my Mac mini M1.
The first step is to disable SIP. Previously, it has worked well by starting in recovery mode running terminal and deactivating through csrutil disable. But now on the M1 Terminal also asked for username and password. See photo. Entered the correct username and password, but then only got back that it failed. Others have been successful with this, why not me? Running Big Sur 11.1.

Macs with Big Sur use zsh rather than bash. I don't know how you got to bash, but try it with zsh.

 

[vwlinkan]

zsh? Lost there, please explain.
Wired keyboard.

Terminal interacts with the system through a shell. The shell supports and runs all of the commands you enter. Beginning with Catalina, Apple changed the default shell from bash to zsh. Your pictures shows bash running for some reason (you see it at the prompt).

Switch to zsh with this command:

chsh -s /bin/zsh

Then proceed with csrutil disable.

Recovery mode still uses bash. This isn’t the problem here.

I have seen this same error posted on another forum before in the past week or so, with no fix or workaround response to it yet, happening on a M1 Mac.

Try changing secure boot to reduced security first. Do a reboot after that and then try disabling SIP again.

 

[vwlinkan]

Will try change to zsh and reduce security.
Thanks!

You're right. I didn't know that.

If you have FileVault enabled you may have to disable that prior to disabling SIP.

I have done so successfully on my Mac mini (M1) but applications are not able to modify /System anymore as that is read-only with Big Sur.

 

[vwlinkan]

I have now tried chsh -s /bin/zsh but that command was unknown
Reducing security also failed, see photo. Hm… any other suggestions?
FileVault i disabled.

Zsh isn't the problem so don't bother with that, and running csrutil should automatically reduce security as required. At least that's how it worked on my test system when I temporarily disabled SIP. My test system also has Filevault enabled so that was not a factor here either.

 

[chabig]

FileVault doesn’t interfere with SIP. I have it enabled and have disabled/reenabled SIP several times.

Looks like there is something screwed up with your system. If you have the time I'd try re-installing macOS and then check if it works. If not, get in touch with Apple.

 

[vwlinkan]

I doubt this is a system problem, I tried this after running it for two days or so.
I will call Apple. But they will probably say the same, reinstall…

I'd agree that something seems to be amiss with your installation. A reinstall is the first logical thing to try.

I have now contacted Apple with my problem and a Senior Adviser will call back tomorrow.

wit a clean user account i think it not will happened again

 

[vwlinkan]

I got a call today from Apple and the adviser have set a technician on the problem. That takes a few days, the Adviser will call back on the seventh of January. I will not try anything before that.

I had essentially the same problem.
The solution for me was to lower security to "Reduced" with the Startup Security Utility, no Filevault.
Afterwards "csrutil disable" works as before. Rebooting wasn't needed.

 

[vwlinkan]

Unfortunately that did not work for me. See image above in this tread.

 

[vwlinkan]

I have now spoken to an Apple senior adviser several times and he have talked to the technicians. We have tried everything (actually more or less what I have tried by myself), including reinstall of the system. Nothing helped. then I was advised to take to a service provider for further diagnose. I will do that on Monday.

You are correct
