How can I use 2 iMacs as dual monitors,
My Late 2012 21.5 inch iMac is running macOS Catalina and I want to connect it to my Late 2012 27 inch iMac which is also running macOS Catalina, I have bought thunderbolt cables, Minidisplay port cables but they are not connecting to each other, I have tried detect monitors, holding down the cmd+f2 but nothing works, are my Macs not able to use this feature?
Hi JACook12,
Sorry, but your configuration for Target Display Mode will not work. The target Mac (2012) must be running macOS High Sierra or earlier.
You should return the cables.
Cheers,
Jack

Look for a HDMI display, then use this adapter to connect it to the Mac: Belkin 4K Mini DisplayPort to HDMI Adapter - Apple.

Is there any alternatives? The smaller Mac is not necessary so if there’s any other way even if I have to purchase a monitor?
You can purchase a LG or HP external display and connect it.

Thanks jack,
would I need any kind of ports once I’ve purchased the display?
Second display
