i have the 2012 27" with a broken hard drive and a small crack in the upper left corner. When I took it to a service center they told me that to repair the hard drive they would have to remove the screen and that would likely cause the screen to break and I would have tore place that too. This made it not cost effective to fix the computer, so I bought the new Mac mini. Now I'm trying to find out if I can use my broken iMac as a monitor for my new Mac mini. The only information I have seen on connecting the two requires me to switch display mode on the iMac, which I can't do. Is there another way to use the iMac as a monitor?
