OS X Mavericks: Set options for accessibility
If you have difficulties with hearing, vision, or mobility, set options in Accessibility system preferences to make your Mac easier to use.
To open the preferences, choose Apple menu > System Preferences, then click Accessibility.
|Display:||Enhance the screen display by inverting colors, changing the contrast, enlarging the cursor, or removing color.|
|Zoom:||Magnify items on the screen by zooming the entire screen or an area of the screen.|
|VoiceOver:||Hear descriptions of what’s on the computer screen, and use the keyboard, gestures, or a braille device to control your Mac.|
|Audio:||Play stereo audio as mono, and have the screen flash when alerts occur.|
|Captions:||Control how subtitles are styled, and whether to use closed captions and SDH instead, when they’re available.|
|Keyboard:||Prevent accidental keystrokes using Slow Keys, and enter modifiers more easily using Sticky Keys.|
|Mouse & Trackpad:||Control the pointer with the numeric keypad using Mouse Keys, or ignore the trackpad.|
|Switch Control:||Turn on Switch Control and use one or more adaptive accessories to enter text and control your Mac. Use the Panel Editor to create custom panels that make it easier to use favorite apps and games.|
|Speakable Items:||Control your Mac by speaking commands that open apps, choose menu items, email contacts, and more.|
To quickly turn on common accessibility features, including Zoom, Sticky Keys, Slow Keys, and Mouse Keys, press Option (⌥)-Command (⌘)-F5.
The Displays, Sound, Keyboard, Trackpad, and Mouse panes of System Preferences contain other options that may help you.
