How to Activate Zoom Settings on a Mac

Zoom is a screen magnification accessibility tool available on all macOS and iOS products. On Mac devices, Zoom can magnify on-screen content (including text, graphics, and video) up to 40 times its original size. Follow these steps to activate and edit basic Zoom settings on macOS.

How to Use Advanced Zoom Settings on macOS

From Accessibility > Vision > Zoom, use the Advanced button to change the appearance of zoomed images, zoom percentage, and other specific settings.

Change Screen Image Settings

From the Appearance tab, select the box next to one of three ways that the Zoom lens image will move while zoomed in:

Select Continuously with pointer to have the Zoom lens image tightly follow the mouse cursor.Select Only when the pointer reaches an edge to have the Zoom lens image trail the mouse cursor, only moving when it reaches the edge of the lens image.Select So the pointer is at or near the center of the zoomed image to have the zoom lens image move with the cursor, but not as tightly as with the first option.

Set a Magnification Range

Set a magnification range to prevent images from becoming too large or too small when zoomed in or out. From the Controls tab, use the two slider scales to choose a minimum and maximum zoom range.

Change the Mouse Cursor Size

Enlarge the size of the mouse cursor to make it easier to see when you use Zoom. From System Preferences > Accessibility, select Display > Cursor size. Use the slider to adjust the size of the cursor. Whatever size you choose will remain even after you log out, restart, or shut down the device.

How to Use Zoom on iOS

Zoom can be used on iOS devices as well, though the magnification range is smaller. It can magnify up to 15 times.​​ All the standard iOS gestures—tap, flick, pinch, and rotate—still work while Zoom mode is on.
