In my examples, throughout this tutorial, I shall use one iMac, an external Mac mini and a cable. In order to use Target Display Mode, both Macs must be turned on and must be awake (ie: not in sleep mode). Particular combinations of Macs, and cables, are required for Target Display Mode, as shown in the table below: Use this cableĪs can be seen, there are two possible cables that can be used to connect Macs in Target Display Mode. Getting Target Display Mode to work depends upon your set up as it does not work with all combinations of Macs. Using a Mini DisplayPort lead to connect a Mac mini to an iMac to share the screen. Target Display Mode is achieved through the use of either a Mini DisplayPort cable or a Thunderbolt cable in order to share the screen of an iMac with an external Mac. For example, I am able to use Target Display Mode so that my late–2009 27" iMac can display the output from my late–2009 Mac mini. Target Display Mode is a feature that allows you to use the display of an iMac to view the screen output from a second, external, Mac. In this tutorial I will explain a little known feature, named Target Display Mode, and show you how to use it. Given that the iMac has a superb display, it could be useful to share that with another Mac, on occasion.


It’s not that you’ll necessarily notice it immediately, but if you ever move back to a PC monitor, you’ll become acutely aware of the difference in quality. One of the things about the iMac, in fact any Apple-made display, is it’s extremely high quality image and colour-depth.
