Apple’s MacBooks come with many vision accommodations built-in. These settings allow changes in color, contrast, zoom etc. There are also keyboard shortcuts which can turn these features on or off.
1. Vision Settings
Many of these features can be explored and changed in the Accessibility pane of System Preferences (not the Display pane).

2. Vision – Display Settings
Inverting Colors, increasing contrast and cursor size can be controlled under the System Preferences > Accessibility > Display tab.
3. Vision – Zoom Settings
Turning on shortcuts to enable zooming of the screen can be accessed under the System Preferences > Accessibility > Zoom tab.
4. Vision – VoiceOver
VoiceOver is a powerful navigation tool for those students with severely limited vision. This tool allows students to use keyboard commands to navigate the interface and read the entire screen for the user. In other words, students hear the MacBook speak the design of the app and its contents, settings, etc.
