In today’s digital world, where multiple devices have become the norm, the ability to seamlessly integrate and utilize them in tandem can be a game-changer. One such scenario is using your iMac as an external display for your Mac PC or MacBook, allowing you to expand your workspace and enhance your productivity. This comprehensive guide will walk you through the steps to achieve this setup, ensuring you make the most of your Apple ecosystem.
Understanding the Concept Before we dive into the nitty-gritty of the setup process, let’s first understand the concept of using an iMac as an external display. Essentially, this process involves connecting your iMac to another Mac or PC and configuring it to mirror or extend the display, effectively turning your iMac into a secondary or additional screen.
The benefits of this setup are manifold. Not only does it provide you with a larger workspace, but it also allows you to multitask more efficiently, reducing the need for constant window switching and maximizing your productivity. Additionally, the iMac’s high-resolution Retina display ensures that your content is displayed with exceptional clarity and detail.
Cabling Solutions: The Wired Approach One of the most straightforward methods to connect your iMac to another Mac or PC is through a wired connection. This approach offers a stable and reliable connection, ensuring minimal latency and seamless performance.

Step#2.On your Mac, go to System Preferences > Displays.
Step#3.Click on the “Add Display” button and select your iMac from the list of available devices.
Step#4.Your Mac’s display should now be mirrored onto your iMac.
Target Display Mode:
A Legacy Solution For older iMac models with bi-directional Mini DisplayPort or Thunderbolt ports, Apple offers a feature called Target Display Mode, which allows you to use your iMac as an external display for another Mac. To enable Target Display Mode, follow these steps:
Step#1.Connect your iMac to another Mac using a Mini DisplayPort or Thunderbolt cable.
Step#2.Press the “Command + F2” key combination on your iMac’s keyboard to trigger Target Display Mode.
Step#3.Your iMac should now function as an external display for the connected Mac.
It’s important to note that Target Display Mode is only compatible with macOS High Sierra or earlier versions for the iMac, and macOS Catalina or earlier versions for the connected Mac.
Compatibility
Compatibility and Requirements Before attempting to use your iMac as an external display, it’s crucial to ensure that your devices meet the necessary compatibility and hardware requirements. Here’s a quick rundown of what you’ll need:
