Hey guys - have an older 2012 iMac and trying to connect to a new iMac to use as 2nd monitor. Connected with Thunderbolt cable and Thunderbolt vis C adapter, tried the command F2 but no go. Tried using original keyboard from 2012 Mac, still no go. Any ideas??
You cannot use the 2012 iMac as a second monitor for a new iMac. That configuration is no longer supported by Apple.
The target display mode was deprecated by Apple in software with the release of Big Sur and was excluded in 2014 and newer iMacs.
Sorry, my friend.
