To use external devices with your other Mac, connect them directly to the other Mac, not to your iMac. If the option isn’t there, the Mac may not support the feature at all. If the Mac supports AirPlay Mirroring, you will find the AirPlay Mirroring option.

Look for AirPlay Mirroring option near the bottom of the Displays preference panel, click this menu and select Apple TV. The other Mac can't use the iMac computer's built-in camera or ports. Open System Preferences and click on Displays. For example, if you begin playing music on your iMac and then enter target display mode, the music doesn't pause on your iMac. Or disconnect the cable, or restart either Mac.Īpps that were open on your iMac when entering target display mode remain open in target display mode.

You can use more than one iMac as a display, if each iMac is using a Thunderbolt cable to connect directly to a Thunderbolt port on the other Mac (not the other iMac).
