Disable SIP on Macos

System Integrity Protection (SIP) is a security layer that limits even the root user from modifying protected parts of the system. Apple introduced it in OS X El Capitan to reduce the blast radius of malware and accidental system damage. In practice, SIP blocks writes to system locations, prevents runtime injection into protected processes, and restricts some kernel/system-level operations.
Sometimes I run a command and see ‘Operation not permitted’ despite sudo, SIP is often the reason. So I need to disable SIP temporarily.
