How to disable the System Integrity Protection of a iMac

Apple introduced the System Integrity Protection (rootless) mode as a security feature as of OS X El Capitan. It prevents you (and programs) from changing root-level files even with your password, but it can stop some programs from working. Here's how you can disable it:

1. Turn off your Mac (Apple > Shut Down).
2. Hold down Command-R and press the Power button. Keep holding Command-R until the Apple logo appears.
3. Wait for OS X to boot into the OS X Utilities window.
4. Choose Utilities > Terminal.
5. Enter

csrutil enable.

1. Enter reboot.

Enjoy,
