Simple: Alert Sounds You Can See

This entry is part 4 of 14 in the series Mac Accessibility 101

ATMac LogoMac OS X makes an alert “beep” sound if you try to press a key that’s not recognised or do various other things that confuse it. Here’s how to set it up so you will get a visual screen flash instead of the audio beep.

Open System Preferences - it’s the fourth item in the Apple menu (the  shape) in the very top left corner of the screen as shown here:

Opening the Apple menu to start System Preferences

In the “System” section, usually about the fourth line of icons in System Preferences, there is an icon labeled “Universal Access” which looks like a guy with his arms out on a blue circle. Click on the Universal Access icon.

The Universal Access pane has sections labeled “Seeing”, “Hearing”, “Keyboard”, and “Mouse”. Click on the “Hearing” section and you’ll see the option to flash the screen when there’s an alert sound - select that option.

Universal Access section of the System Preferences pane open to the "Hearing" section.

You can also use the test button to see how the screen flash looks.

Note that once you’ve selected this option, you won’t get the audio beeps - it’s an either/or and there’s no “both” option which I think is a mistake. But I don’t code for Apple’s accessibility team so I guess I don’t get to choose.
