Connecting iMac to mac mini
Hi. I would like to connect a late 2014 imac to a new mac mini (big sur both) to use the imac as a monitor. What cables and/or adapters do i need to buy exactly?
iMac 21.5″, macOS 11.0
You do not need to buy cables because it won't work.
Why....? Because the new Mac Mini can't use your 2014 iMac as a display in Target Display Mode.

If you buy or have a new Mac Mini, then you will need an external display for it.
