You can set options to switch the screen to grayscale for more visual contrast, zoom in on the screen in a separate window to make it larger and easier to see, use VoiceOver so you can hear descriptions of screen items, have the screen flash when alert sounds occur, use Sticky Keys or Slow Keys to help control the keyboard, use Mouse Keys to make mouse functionality available on the numeric keypad, and use speech recognition to control your computer, such as using menus, using spoken commands. If you’re not sure where to find an option, you can use the Search field. You can the Accessibility pane anywhere on your Mac with the Image+Option+F5 keyboard shortcut (New!).
