  • Enabling/disabling System Integrity Protection in macOS

Starting with OS X El Capitan, Apple, Inc introduced System Integrity Protection (SIP), a security feature that protects the essential parts of OS data on the system disk from unwanted alterations. It increases the level of system security, but at the same time severely restricts access to files on the disk, rendering file recovery impossible. It should be disabled to perform file recovery.

To do this:

1. Restart your Mac computer.

2. Simultaneously press and hold the Cmd and R keys during startup and boot the computer into the macOS Recovery mode.

When the recovery process is over, System Integrity Protection should be re-enabled again.

To do this:

1. Proceed with above steps 1 to 3.

2. In the Terminal, type in "csrutil enable" and press Enter. There should be a message that System Integrity Protection was successfully enabled.
