System Preferences is a small app that you can easily access where you can change some basic settings on your Mac. System Preferences is broken into categories, and then each category can be further broken down into subcategories with the names at the top. In macOS, unlike Settings in iOS, System Preferences is where you can find system settings, but not app preferences. Those are found in each individual app.
