Improvements in Mac OS X 10.6 aid users with physical disabilities Mac OS X 10.4 (Tiger) introduced a host of features that made using a Mac easier for people with physical disabilities. Among its key improvements was VoiceOver, a screen reader that narrated whatever was on the Mac’s display. Leopard improved on those features, adding a more human-sounding computer voice (Alex) and offering more ways to interact with the Mac (including support for USB Braille displays and number-pad input). Snow Leopard continues those efforts to make OS X more accessible.
