Hello, yeti0810.


Here are the rules for Target Display mode on iMac:

click> Use your iMac as a display with target display mode - Apple Support


Target display mode is a feature that was available only with certain older iMac models.


Only the following older iMac models can be used as an external display when plugged into another older Mac model:

  • iMac models introduced in 2011, 2012, 2013, and mid 2014 using Thunderbolt or Thunderbolt 2 cable.
  • 24-inch and 27-inch iMac models introduced in 2009 and 2010 using Mini DisplayPort cable.
  • The intended target iMac must be running macOS 10.13 High Sierra or earlier; it does not work with macOS 10.14 Mojave or later, or with Boot Camp and Windows.
  • Retina display iMacs won’t work as target displays.
  • In all cases the source Mac that you're connecting FROM must have been introduced in 2019 or earlier and have macOS 10.15 Catalina or earlier installed.
