Set Accessibility preferences on Mac
If you have difficulties with vision, hearing or mobility, try out the wide range of Accessibility preferences on your Mac.
To change these preferences, choose Apple menu > System Preferences, then click Accessibility.
Turn on or off VoiceOver, the built-in screen reader that describes aloud what appears on your screen, open VoiceOver Utility or start the VoiceOver tutorial. See VoiceOver preferences.
Make content on the screen larger and easier to see by zooming the entire screen or an area of it, or by using Hover Text. If you’re using a second display, set the zoom for it separately. See Zoom preferences.
Modify the screen display by inverting colours, reducing the motion of items, changing the contrast, reducing the transparent effect on some backgrounds and using shapes instead of colours to differentiate items. See Display preferences.
Make the cursor temporarily bigger or change its size. See Cursor preferences.
Apply colour filters (such as a red/green filter for protanopia) or a colour tint to the screen. See Colour Filters preferences.
Customise the system voice, hear when alerts or apps need your attention, have selected text spoken when you press a designated key, or have items under the pointer spoken. See Speech preferences.
Hear a description of the visual content in films, TV programmes and other media, if descriptions are available. See Descriptions preferences.
Have the screen flash when alerts occur, and play stereo audio as mono. See Audio preferences.
Control how subtitles are styled, and whether to use closed captions and SDH instead, when they’re available. See Captions preferences.
Note: These preferences are shown only when you have set up your iPhone and Mac for Wi-Fi Calling and RTT phone calls are enabled on your iPhone. RTT is not available in all countries or regions, or supported by all network providers.
Control your Mac and apps with your voice by speaking standard commands or commands you create. See Voice Control preferences.
Enter modifiers more easily using Sticky Keys, prevent accidental keystrokes using Slow Keys, or have your Mac speak what you type, select or press using the keyboard. See Hardware preferences.
Turn on the Accessibility Keyboard as an alternative to a physical keyboard, and use Dwell options to control the pointer with a tracking device. See Accessibility Keyboard preferences.
Make your mouse or trackpad easier to use. See Mouse & Trackpad preferences.
Control the pointer with the numeric keypad using Mouse Keys; use keyboard shortcuts, assistive switches or facial expressions to perform certain mouse actions; or move the pointer using head pointer. See Alternative Control Methods preferences.
Turn on Switch Control and use one or more adaptive accessories to enter text and control your Mac. See Switch Control preferences.
Type your requests to Siri instead of speaking them. See Siri preferences.
Select the items to include in the Accessibility Options shortcut panel. See Shortcut preferences.
Other System Preferences, such as Displays, Sound, Keyboard, Trackpad and Mouse, offer additional options that may help you.
