Use shapes, in addition to or instead of color, to convey status or information.
Stop or reduce the movement of elements on the screen—for example, when you open apps, switch between desktops, or open and close Notification Center.
Increase the contrast of items on the screen (such as borders around buttons or boxes) without changing the contrast of the screen itself.
Replace the transparent effect used on some backgrounds in macOS with a darker background, to improve contrast and readability.
Increase the screen contrast.
Increase the size of the pointer.
Shake mouse pointer to locate
Quickly move your finger on the trackpad or quickly move the mouse to temporarily enlarge the pointer so you can find it.
You can enable keyboard shortcuts for inverting colors and changing the contrast in the Accessibility section of the Shortcuts pane of Keyboard preferences. To open the pane, choose Apple menu > System Preferences, click Keyboard, then click Shortcuts.
