How can I hook up a second monitor to my iMac 24 inch
I recently bought a new iMac 24 inch and I would like to set up a second monitor with it. I have tried to plug in a second 2012 iMac and hit Command F2 but nothing happens. This would work before with my 2019 iMac. What is the best route to hook up a second monitor with the new iMac 24-inch?
iMac 24″, macOS 12.3
