If your Mac is showing an error message, "Drive File Stream Requires Your Approval Message" with directions to update privacy and security in preferences, this video will show you exactly what to do.
Google and Apple (not sure which to blame here) have really hidden, or just failed to explain how to get rid of this message. It's simple once you know how, so I made this quick video once I figured it out.
BTW, I used to be an IT guy and I tried to figure this out about a dozen times before actually fixing it. Every time I rebooted, there was the message.
Here's how to fix it.
