Using my old iMac as a screen-only

[toon79]

I have a new MacBook (spec attached) and I'd like to connect it to my old iMac (spec also attached).

My iMac is a late 2015 so I can't use Target Display and the MacBook is just USB-C. I can connect a cable that is USB-C to USB-C and I can easily turn Screen Mirroring on my iMac shows up on my MacBook just fine but there's no option to reverse it.

Any help would be much appreciated.

The easiest way to do this is to use a Luna Display (https://astropad.com/product/lunadisplay). You would plug the Luna Display dongle into your MacBook Air, and then run the Luna Secondary app on the iMac. The iMac will need to be running macOS 10.13 or later.

That's what I've heard. Thank for the confirmation

$128 just to use my iMac as a screen. I could buy a display for that.

You would need the USB-c version, which is on sale for $59 today. Nice thing is that the Luna Display also allows you to use an iPad as a 2nd display when traveling.
