System Integrity Protection (SIP)
Apple has implemented a new security feature, System Integrity Protection (SIP), starting with OS X 10.11. SIP prevents anyone from altering the contents of files in key System folders and is designed to protect System files from malware and viruses. SIP also affects third-party apps like Winclone that need to write to files now under protection of SIP. If you are getting an message that the boot sector cannot be updated, or that SIP needs to be disabled, this article may help.
Disabling SIP is a quick and easy process that can be easily re-enabled again after restoring the Winclone image.
Note: Saving/creating a Winclone image does not require disabling SIP.
How to Disable SIP
Disabling SIP requires booting into the recovery partition to run the Terminal command below.
