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
