imac 21.5 inch as a secondary display for macbook pro 13 inch

Is there anyway to connect my Macbook pro, retina 13 inch to my imac retina 4k, 21.5 inch to use the imac as a secondary device?


currently i'm using screensharing on the imac but would really help if i can use it more like a secondary monitor than to run the macbook pro from an app...


MacBook Pro 15″, OS X 10.10

Nope. The Retina 4K iMacs have never supported Target Display Mode.


If your devices are new enough Apple may add Airplay-to-Mac support with Monterey, but for now a screensharing app is the closest you can get.
