The Sims 4 continues to receive "Not Optimized for Your Mac" warnings because not everything has been updated to be 64-bit, specifically, the ActivationUI.app. In other words, there are still components that will stop functioning with the next macOS update (Catalina, due out this Fall).
When is it expected that this component will be updated?
