System Integrity Protection

System Integrity Protection (SIP) is a security feature that protects all the Apple applications and utilities, certain operating system processes, files, and folders from being modified. Thus, the /System, /bin, /sbin, and /usr folders (except the /usr/local folder) are protected.

SIP is turned on by default but can be turned off from the macOS Recovery partition.

To disable SIP:

1

Quit OnyX.

2

Restart the computer while holding down Command-R until the macOS Utilities pane appears.

3

In the Utilities menu, select Terminal.

4

Enter the following command and press Return:

csrutil disable

5

Quit Terminal.

6

Restart normally from the Apple menu ().
