If you have an iMac built between 2009 to 2014 with Target Display Mode, you an use it with your Intel Mac Mini, Intel MacBook Air or Intel MacBook Pro as an external monitor. This is because the resolution in Retina iMacs was so high, that a Thunderbolt port would not be powerful enough to support it without increasing the bandwidth of Thunderbolt ports to support Retina displays. Unfortunately, in 2014/2015 when Apple released the first Retina Display iMacs, it removed the Target Display feature from the iMac. Target Display Mode allows you to use an iMac as an external display. Only iMacs from 2009 to 2014 can be used as an external display with another Mac because they have something called Target Display Mode which Apple has since dropped from the iMac. Not all iMacs can be used an external monitor. Using Luna Display (Intel & M1/M2 Macs)Ĭan All iMacs Be Used As An External Monitor?
