Terminal is an unauthorized program?

I downloaded citra onto my macbook, but when I try to open it, it says “Terminal is an unauthorized program.” I have no idea what that means. I tried every Nightly Build and the same thing always happens.
I have a 64 bit Macbook Air with macOS Sierra v. 10.12.

I am not a Mac user, but ive heard abt similar errors in other apps as well. Try launching from an admin account, or building Citra yourself. Hope it gets fixed.
