iMac for 2nd Monitor
I have a late 2012 27" iMac and have been told by Apple multiple times that I can connect it to my new 16" MacBook Pro. I want to use my 27" iMac to act as a second monitor so I can work on both screens with different programs at the same time or it can even just reproduce what's on the 16" MacBook if I can't use it as two screens working in conjuntion. What cable(s) can help me do this? If not cables, what can I do?
iMac 27″, macOS 10.12
