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.

After that reboot your system and it should be disabled. To check if it is disable you can open a terminal and type:

   csrutil status

That's all!
