Sound and vision: The Sound and Displays system preferences
Your Mac is capable of both aural and visual wonders. Two system preferences—Sound and Displays—control how those wonders are manifested.
Sound
The Sound preference governs the majority of the Mac’s audio capabilities—the sound effects it uses, its audio volume, the audio devices the Mac plays audio through, and the input it uses to receive or record audio. The settings for these variables appear on three tabs: Sound Effects, Output, and Input. Let’s run through them now.
Sound Effects tab
Choose a new alert sound within the Sound Effects tab.
You know those little beeps and boops your Mac makes when it’s unhappy about something—when you’ve tried to close an application while a dialog box is present or when you’ve attempted to click something that makes your Mac irritable? Those are rightly called sound effects, and you can configure them on the Sound preference’s first tab.
If you’d prefer a different alert sound to the one you’re currently hearing, simply select one from the list—it will play when you select it. (Old-time Mac users may favor Sosumi.)
