In order to check whether System Integrity Protection (SIP) is enabled or disabled on a Mac running OS X El Capitan, you can use the csrutil command to report on SIP’s current status. For example, to learn if SIP is enabled or disabled, run the following command:
csrutil status
This command can be run without root privileges and will tell you if SIP is on or off.
If SIP is enabled on 10.11.0 or higher, you should receive the following message:
System Integrity Protection: enabled
If SIP is disabled on OS X 10.11.0 or 10.11.1, you may receive a confusing message which indicates that SIP is enabled, followed by a list of individual SIP functions which are disabled. If all functions listed are showing as being disabled, SIP is actually completely disabled; it’s just confusingly worded.
It appears that Apple has updated the status message on OS X 10.11.2 to make it much more clear when SIP is disabled. On 10.11.2, if SIP is disabled, you now should receive the following message:
System Integrity Protection: disabled
