I have connected the two IMACS via a thunderbolt 2 to thunderbolt 2 cable directly, but can not get the 2010 to serve as a monitor despite using Command F2 and FN-Command F2
Am I out of luck?

Jack, thank you. It is a 21.5 mid 2010 with 10.13.6 I had mistyped based on another IMAC I had owned.
OK, thanks for confirming!
Unfortunately, the iMac (21.5-inch, Mid 2010) isn't compatible for Target Display Mode, only the 27-inch model. However, there is a third-party solution called Luna Display that might work for you. I recommend checking it out.
I hope this helps!
Cheers,

Hi Rturbin,
Apple never made a 24-inch Mid 2010 iMac, only a 21.5-inch and a 27-inch from that model year.
If you could, would you please confirm what model you do indeed have?
Thanks!

In addition, I wanted to let you know that for your configuration, you should order the Mini DisplayPort version of Luna:
Both Mac computers must be running OS X El Capitan or later.
Also, on your older Macs, the default, wireless Luna connection may be slow. If you experience less than ideal performance with Luna, you may want to use a wired connection. Should this happen, refer to: How do I use a USB, Ethernet, or Thunderbolt connection? - Luna Display Astropad Support.

So you believe a minidisplay port to minidisplay port will allow The 2010 24" 10.13.6 to act as a monitor to a 2012 27" 10.15.7, both IMACS? The Thunderbolt 2 to Thunderbolt 2 didn't work even though the specifications on each unit seem to support it. I have found conflicting reports that the 2012 source IMAC might have to be 10.13 "High Sierra or Lower"
The 2012 27 inch I wish to use as source has 10.15.7, and the 24 2010 inch imac to be used as screen has 10.13.6, and the cable is Thunderbolt 2 to Thunderbolt 2. I therefore believe it fits your description but I can not get the 2010 to act as a monitor. Im using original keyboard and have tried a second
You need the mini DisplayPort cable, not a Thunderbolt cable.
The doc was linked earlier, and describes what works per Apple.
This would generally not be my preferred display configuration.
Jack, thank you. It is a 21.5 mid 2010 with 10.13.6 I had mistyped based on another IMAC I had owned.
