Stop or reduce on-screen motion on Mac
You can stop or reduce the movement of some elements on the screen — for example, when you open apps, switch between desktops, or open and close Notification Centre. This feature is especially useful for people who experience motion sickness or vertigo.
You can also automatically dim the display of content that depicts flashing or strobing lights, and pause the display of rapid animated images such as GIFs.
On your Mac, choose Apple menu > System Settings, click Accessibility in the sidebar, then click Display on the right. (You may need to scroll down.)
Do any of the following:
Reduce the motion of the user interface: Turn on “Reduce motion”.
Automatically dim the display of content that depicts flashing or strobing lights: Turn on “Dim flashing lights”.
Note: This option is available only for supported media and on Mac computers with Apple silicon. Content is processed on device in real time. “Dim flashing lights” should not be relied upon for the treatment of any medical condition.
Automatically pause the display of rapid animated images (such as GIFs in Messages and Safari): Turn off “Auto-play animated images”.
