Zoom is a powerful built-in magnifier that lets you enlarge your screen up to 20 times, so you can better see what’s on the display. You can use it full screen or picture-in-picture, allowing you to see the zoomed area in a separate window while keeping the rest of the screen at its native size. The hardware acceleration engine lets you boost the size of everything on your screen — text on a web page, family photos, a place on a map.
To access the Zoom feature on your Mac, go to System Preferences and then click on Accessibility.
