Disabling SIP without full Recovery mode
You can disable SIP entering in Single User Recovery mode.
To do that you have 2 ways:
Using local recover partition
- Power off your notebook.
- Power on, than hold: option
- Select your Recovery Partition holding: command + S
- You will see a boot in a "console/terminal" mode.
- run cmd: csrutil disable
- run cmd: reboot
Using internet recovery
- Power off your notebook.
- Power on, than hold: command + shift + R
- Select your Wi-Fi
- Wait to download the recovery "image" from internet (progress bar with World/Internet logo).
- When at end of download, hold: command + S
- Keep holding "command + S" until boot start (progress bar with apple logo).
- You will see a boot in a "console/terminal" mode.
- run cmd: csrutil disable
- run cmd: reboot
Sometimes your notebook won't enter in full recovery mode. Single user mode is very useful when this happens.
