Accessibility (System Preferences)

The Accessibility pane (formerly Universal Access) of the System Preferences in macOS was developed by Apple to allow users with disabilities to customize the display and input settings of their Mac.

Usage
Users can be accommodated for disbilities related to vision, hearing, mobility, or learning. Users will be alerted when 3rd-party accessibility software attempts to access data on their Mac. The Security & Privacy preference pane can be used the limit the amount of access such software can have to a user's private data.

History
With the first release of Mac OS X, the Universal Access preferences pane superseded the Easy Access control panel from classic Mac OS. It was renamed "Accessibility" in Mac OS X 10.8 (Mountain Lion).
