As technology continues to advance, our old devices can easily become outdated and end up in the junkyard or, worse still, collecting dust in some forgotten corner of our homes. However, for Mac enthusiasts, there’s a way to breathe new life into an old Mac by repurposing it as a monitor. This creative solution not only prolongs the lifespan of your Mac but also provides you with an additional display for multitasking, gaming, or simply enjoying your favorite shows. In this article, we’ll delve into the world of Mac-turned-monitors and explore the steps you need to take to set one up.
Understanding the Basics
Before we dive into the process, it’s essential to understand the requirements for using your Mac as a monitor. This setup is possible thanks to a technology called ‘Target Display Mode’ (TDM). Introduced by Apple in 2009, TDM enables users to transform their Mac into a display by simply pressing a few keyboard shortcuts or connecting it to another device.
Target Display Mode is available on the following Mac models:
- 2009 iMac (24-inch) and later
- 2010 iMac (27-inch) and later
- 2009 Mac Mini (late model)

The second device will see the Mac as a regular monitor, and you’ll be able to stream content, use it as an extended desktop, or mirror the display.
To enable Target Display Mode, you’ll need to connect the two devices using a Thunderbolt, Thunderbolt 2, or Thunderbolt 3 cable. Once connected, press the ‘T’ key on the Mac you want to use as a monitor while restarting it. The Mac will then recognize the second device and switch into Target Display Mode. When in this mode, the Mac will not be able to function as a standalone computer, but it will provide an excellent display experience.
Can I use my Mac as a monitor for a PC?
Yes, you can use your Mac as a monitor for a PC. However, you’ll need to use a third-party app, as Target Display Mode only works between two Macs. There are several apps available that allow you to connect your Mac to a PC and use the Mac as an external display. These apps usually require you to download software on both devices, pair them, and then you’ll be able to stream content from the PC to the Mac.
Some popular apps for sharing your Mac display with a PC include Air Display, Duet Display, and Luna Display. These apps allow you to stream content wirelessly or via a cable, depending on the app’s capabilities. The good news is that these apps usually work seamlessly, and you’ll be able to use your Mac as a monitor for your PC with minimal setup.
Do I need any special hardware to use my Mac as a monitor?
To use your Mac as a monitor, you’ll need a compatible Thunderbolt, Thunderbolt 2, or Thunderbolt 3 cable. The type of cable required depends on the type of ports available on both devices. If your devices only have USB-A ports, you won’t be able to use your Mac as a monitor, as it requires the faster speeds provided by Thunderbolt or USB-C.
However, if you want to connect your Mac to a device wirelessly, you won’t need any special hardware, as long as both devices have Wi-Fi capabilities. There are many third-party apps that can help you achieve this, and some of them are free to download. Keep in mind that the wireless connection might not be as stable as a wired connection, but it can be convenient if you don’t want to deal with cables.
Can I use my Mac as a monitor for a gaming console?
Yes, you can use your Mac as a monitor for a gaming console. However, you’ll need to ensure that the gaming console supports the resolution and refresh rate of the Mac’s display. Most modern gaming consoles, such as the PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X/S, support HDMI output, so you can connect them to your Mac using an HDMI cable.
When using your Mac as a monitor for a gaming console, keep in mind that you might experience some lag or latency, especially if you’re connecting the console wirelessly. The good news is that many Macs have excellent displays with low input lag, making them suitable for gaming. However, you might need to adjust the display settings on the Mac or console to achieve the best gaming experience.
Will using my Mac as a monitor affect its lifespan?
Using your Mac as a monitor can potentially affect its lifespan, as it can cause wear and tear on the device’s hardware. When in use as a monitor, the Mac’s display, CPU, and memory are engaged, which can reduce the overall lifespan of the device. Additionally, the Mac will still be using its internal components, such as the graphics card and RAM, to process the display signal.
However, if you’re using a Mac that you no longer intend to use as a primary computer, repurposing it as a monitor can extend its lifespan in terms of usage. By giving the Mac a new purpose, you’re essentially extending its life and reducing electronic waste. Just make sure to keep the Mac updated with the latest software and take proper care of it to ensure it continues to function well.
