csrutil disable doesn't work when executed from Terminal

[raykyri]

Has anyone else gotten this error when running csrutil disable?

csrutil: failed to modify system integrity configuration. This tool needs to be executed from the Recovery OS.

Thanks for filing @raykyri. It looks like https://apple.stackexchange.com/questions/208478/how-do-i-disable-system-integrity-protection-sip-aka-rootless-on-macos-os-x covers how to run the command. I'll update the README

Anyway the howto slightly differs for Apple M1 (newer machines):

1. Shutdown mac.
2. Start it while holding start button until Options is shown.
3. Select Options->Login->Utilities->Terminal
4. Run csrutil disable
5. Login again
6. Reboot
7. Done.
