Enable or Disable System Integrity Protection Rootless in Mac OS X
Apple has enabled a new default security oriented featured called System Integrity Protection, often called rootless, in Mac OS from versions 10.11 onward. The rootless feature is aimed at preventing Mac OS X compromise by malicious code, whether intentionally or accidentally, and essentially what SIP does is lock down specific system level locations in the file system while simultaneously preventing certain processes from attaching to system-level processes.
While the System Integrity Protection security feature is effective and the vast majority of Mac users should leave rootless enabled, some advanced Mac users may find rootless to be overly protective. Thus, if you’re in the group of advanced Mac users who do not want SIP rootless enabled on their OS X installation, we’ll show you how to turn this security feature off.
