I wanted to come back with an update. The Luna Display you recommended did not work, as I want to use my 2017 iMac as the second screen. But the same people that make the Luna Display (Astropad) also make a device that does work. It's called the Luna Mini Displayport. I can now see and control my 2012 iMac from my 2017 iMac.
Thank you, Keith Barkley! I would probably never have found it without your suggestion.
I wanted to my update here where it can be more easily seen. A company called Astropad makes a device called the Luna Mini Displayport. I can now see and control my 2012 iMac from my 2017 iMac. I discovered this device due to the suggestion I received here from Keith Barkley.
There is a software option called Luna Display
What OS' do you have on both machines?
The article linked above is pretty specific as to what will work.
The linked article says I cannot. I was hoping someone had a work-a-round.
My 2012 is running Mojave 10.14.6
My 2017 is running Ventura 13.3.1
Unfortunately, my 2012 iMac is running Mojave 10.14.6.
I'll look that up. Thanks.
The only way I have found is a capture card or using Airplay, and yes. I am running Ventura on my 2013 iMac with OCLP and it does support airplay and it works beautifully
Please see the thread under Keith Barkley. I found a solution that works.
