Hi guys, I'm new to this forum, hope this post is in the right topic list. I own a macbook pro (macOs: Big Sur 11.2.3) to which I connected a simple external monitor via HDMI cable to extend the macbook destop. Also I have an old 27 "iMac from 2012 (macOs High Sierra) that I would like to use as an additional external monitor. To do this I bought a thunderbolt cable to connect two macs. So when the macbook pro is on I tried to connect it to the iMac as well, and then again from the iMac I pressed "cmd + F2" (both during startup, and with the iMac already on) to put the iMac in "Target Display Mode". The iMac however does not recognize this command and therefore I cannot use it as a second external monitor.
I tell you right away that the two Macs recognize the connection via thunderbolt, and I also tried the combination "cmd + fn + F2".
Can you give me some advice to solve the problem?
Thanks!
