“Vehicle Motion Cues

Vehicle Motion Cues may help reduce vehicle motion sickness while using a Mac and riding as a passenger in a car or other on-road vehicle.

To customize Vehicle Motion cues, click Customize Appearance, then set any of the following options:

- Pattern: Select Regular for a stable and predictable pattern of onscreen dots, or Dynamic for a more engaging visual experience.

- Color: Select a color of onscreen dots. Color saturation will automatically adjust to maintain contrast with the content behind each dot.

- Larger dots: Turn on Large dots to increase the size of the dots that appear onscreen.

- More dots: Turn on More dots to increase the number of dots that appear onscreen.

Note: This option is available on Mac laptop computers. It’s not available on MacBook Air (M1) or 13-inch MacBook Pro (M1) or earlier.”

It’s also for macOS
