Finally, next to the Voice Feedback heading, check Off. If you’d prefer this option, click the Apple menu, followed by System Preferences and Siri. Siri doesn’t have to speak her responses aloud-she can silently display them on screen. Dig deeper, however, and you’ll find a heap of useful settings and options that let you customize your computing experience. Apple prides itself on the polish and slickness of its software, and on the surface, macOS proves itself an intuitive and easy-to-navigate operating system.
