Is it possible this machine had our nix-installer run on it before?

If you try the install again, does it go any further?

If it happens again, before you run the revert steps, could you show the output of launchctl print system/systems.determinate.nix-installer.nix-hook?

After installing john, my nix when dead, I've used nix-darwin I followed the process to uninstall it, but nothing is working now.

Tried to reinstall as you said @cole-h same same, same error seems that's stuck at the same stage.

[cole-h]

Does anything change if you manually run the launchctl bootout command it failed on?

[viniciuspalma]

No, now the file not even exist.

I guess we might need to check if the file even exists before we try to bootout. Thanks for that information.

Are you sure it wasn't just trying it again that fixed it? I'd expect a different error to show up if /etc/synthetic.conf had bad permissions...

Regardless, glad you were able to proceed further!

@viniciuspalma do you have a huge number of watchman processes in ps -ef ? Maybe unrelated but i had just posted a similar issue and updating brew and watchman seems to have helped.
