Apple’s Commitment to Accessibility

For more than 20 years, Apple has provided new and innovative solutions for people with disabilities, allowing them to access — and enjoy using — the Mac, iPod, iPhone, iPad, and Apple TV.
Apple includes assistive technology in its products as standard features — at no additional cost. For example, iPhone, iPad, iPod, and OS X include screen magnification and VoiceOver, a screen-access technology, for the blind and visually impaired. To assist those with cognitive and learning disabilities, every Mac includes an alternative, simplified user interface that rewards exploration and learning. And, for those who find it difficult to use a mouse, every Mac computer includes Mouse Keys, Slow Keys, and Sticky Keys, which adapt the computer to the user’s needs and capabilities.
By listening to our customers and applying thoughtful solutions to previously unsolvable problems, Apple continues to set a high standard for accessibility. Inventions such as braille mirroring, which enables deaf and blind kids to work together on the same computer at the same time; the world’s first screen reader that can be controlled using gestures; and captioning of downloadable digital movies are perfect examples of Apple innovation.
As part of our commitment to accessibility, our Retail Associates are specially trained to serve customers with disabilities. Please ask an Associate for assistance if you have difficulty viewing a product when you visit an Apple Retail Store. The Associate will be happy to assist you by moving displayed products to more accessible locations if possible.
On this site, you’ll find additional information about the many accessibility features built into Apple products.
