I'm on OSX El Captain and I would like to rename the file "usr/bin/openssl
" into "usr/bin/openssl_old
" (cause I want to update openssl) but when I try it says "operation not permitted" (even as root).
I tried :
-chmod ugo+w
-chmod ugo+w
-csrutil disable
(this one says "csrutil: failed to modify system integrity configuration. This tool needs to be executed from the Recovery OS."
-chown root /usr/bin/openssl -R
-chmod 777 /usr/bin/openssl -R
please help !

It's simply can be done following this steps:
Command+R
);csrutil status
(System Integrity Protection (SIP));csrutil disable
;P.S. If you decide you want to enable SIP later, return to the recovery environment and run the following command:
csrutil enable
and reboot the system.
