It sounds like you are referring to something i posted, with regarding to the security  / privacy settings

Mac No Audio or Video. MacOS Security & Privacy settings. Good To Know.

If you don't see the option, it suggest you have an earlier Mac OS. Which is fine. I personally use Sierra.

You said you're going directly into the Mac. That means, no Audio Interface. Explain how you are connecting to your Mac, specifically what input. And, you are wearing headphones expecting to hear yourself. What instrument are you using, or voice only?

I am plugging my Blue Yeti directly into my i Mac.  No headphones.  I sing.
