Many of the Accessibility visual aids are virtually identical on Macs and iOS devices. There are a number of options for altering colour and contrast settings to improve the visibility of the screen. There’s also a Zoom option that can be used to magnify the entire screen, or just specific areas, such as the headline on a web page.
However, the key feature here is VoiceOver, the ‘screen reader’ program that can read out text from web pages and other documents, and also describe elements such as icons and control buttons that are displayed on the screen of your devices. VoiceOver can also be used to set up Braille displays for use with Macs and iOS devices.
The VoiceOver controls on the Mac are more extensive than on iOS, as they have to accommodate the use of a mouse and keyboard, as well as dealing with the Mac’s more complex graphical interface. There are many different ‘verbosity’ controls that can describe mouse and keyboard actiosn, such as telling you when the mouse cursor moves over an open window, or reading out column headers as you scroll through a spreadsheet. Fortunately, there’s a special training program built into the Accessibility panel on Macs that can introduce you to VoiceOver and help you to set it up in the way that suits you best (you can also read Apple’s full VoiceOver guide at
