This section explains how to use the Magnifier app in macOS 26 Tahoe to magnify the screen. This is a step-by-step guide with pictures of the screens to help.
1. Open the Magnifier app
from the Utilities folder on your Mac (Finder > Applications > Utilities > Magnifier).

Alternatively, press Cmd (Command ⌘) + Space Bar to open Spotlight. In the Spotlight window, click the Applications button, then scroll down and select the Magnifier
app from the list of app icons.


2. By default, the Magnifier app uses the built-in camera on your Mac. To use an iPhone or a connected USB camera, click Camera in the toolbar along the top-left of the screen, then select the camera you want to use.

3. Point your camera at an object or a page of text. Drag the slider at the top of the Magnifier window to zoom in and out, or use the keyboard shortcuts Cmd + (plus) to zoom in and Cmd – (minus) to zoom out.

4. If you would like the Magnifier to fill the screen, click Window in the toolbar along the top-left of the screen, then select Zoom.

5. To apply a colour filter to the image, click the right-sidebar button
in the top-right of the Magnifier window to reveal the sidebar.

6. Select your preferred filter. You can also adjust the brightness and contrast here.

7. To save your filter settings so they are applied automatically the next time you open the Magnifier, scroll to the bottom of the right sidebar and click Save as Default Settings.

8. Sometimes it may be easier to view an item or text you have zoomed in on by capturing it as a still image. To do this, click the Capture Freeze Frame button
in the bottom-right of the Magnifier window.

9. To view the image, click its thumbnail in the left sidebar.

10. You can use the slider to zoom in or out and apply colour filters to the image, just as described above.
11. To return to the live view, click the live view thumbnail at the top of the left sidebar.
The Magnifier’s Reader Mode formats text to make it easier to read. The Magnifier can also use your Mac’s built-in screen reader to read the text aloud.
12. You can use Reader Mode with a live view of text, but you may find it easier to capture a still image of the text first, then view that image in Reader Mode. To do this, point the camera at some text in your surroundings, then click the Capture Freeze Frame button
in the bottom-right of the Magnifier window to capture an image of the text.

13. Click the thumbnail in the sidebar to open it. then, click the Reader Mode button
along the top of the Magnifier window.

14. The text will appear in the Reader window, reformatted for easier reading. To customise the formatting further, click the right-sidebar button
to open the formatting options.

15.To help you get started, several predefined colour schemes are available — all fully customisable to suit your preferences. Choose a scheme from the drop-down menu.

16. The table below lists the features you can customise within a scheme (also, see the screenshot below the table for reference).
