How to Disable System Integrity Protection (SIP)

Since the release of macOS High Sierra some extensions must be approved for the corresponding applications to work as expected. This includes your Intego software as described in the article Allowing Intego Extensions in High Sierra.

There is a known issue in macOS High Sierra that causes this process not to work as expected in some cases. You can read more about it in this Apple discussion thread.

To resolve the issue, a user must either temporarily disable SIP and then re-enable it after installing the software or; perform a clean reinstall of macOS High Sierra. If you choose to temporarily disable SIP, it is important that you uninstall the software, disable SIP, then reinstall the software again.

How To Disable SIP:

First, boot macOS into Recovery Mode. To do this, restart your computer and hold down the Command+R (⌘+R) keys simultaneously when you hear the boot chime.
