Mirroring your Mac’s display can be a useful feature in various situations. Whether you want to share your screen with others during a presentation or simply want to view your Mac’s content on a larger display, mirroring can come in handy. In this tutorial, we will guide you through the process of how to mirror your display on a Mac.

Step 1: Open System Preferences

To get started, click on the Apple logo located at the top left corner of your screen and select “System Preferences” from the dropdown menu. Alternatively, you can also use the Spotlight search by pressing “Command + Space” and typing “System Preferences”.

Step 2: Select Displays

Within the System Preferences window, locate and click on the “Displays” icon. This will open a new window where you can adjust various display settings.

Step 3: Enable Mirroring

In the Displays window, navigate to the “Arrangement” tab. Here, you will see a checkbox labeled “Mirror Displays”. Check this box to enable mirroring.

Note: Enabling mirroring will duplicate your Mac’s display onto all connected displays.

Step 4: Adjust Display Resolution (Optional)

If desired, you can adjust the resolution of your mirrored display(s) by selecting a different option from the available resolutions listed in the “Display” tab of the Displays window. Keep in mind that changing the resolution may affect how content appears on your mirrored displays.


  • If your Mac is not detecting external displays, ensure that all connections are secure and that any necessary adapters are properly connected.
  • If mirroring is not working as expected or you encounter any issues, try restarting your Mac and repeating the above steps.
  • If you are using multiple displays, you can rearrange their positions by dragging and dropping them within the Arrangement tab of the Displays window.


By following the simple steps outlined in this tutorial, you can easily mirror your Mac’s display onto external monitors or projectors. This feature is particularly useful for presentations or when you want to share your screen with others.

Remember to adjust the display resolution if needed and troubleshoot any issues that may arise. Happy mirroring!
