Yeah, this used to work for me on earlier Betas of Big Sur against a 2013 iMac running Catalina and it stopped working completely with a recent update.

I have it working from a Big Sur MacBook Pro to a High Sierra iMac.

Will apple fix this in a software update? Should I return the new cable and adapter? Should I return the laptop too? I'm not sure I want to put up with this after spending nearly $4K on a new computer that doesn't work for my office needs. I have 2 iMacs and both of them are on macOS Catalina, and I can use Target Display Mode on them. I also tried the same process with my 13' MBA and I don't see the 21.5' iMac while in target disk mode. I put my 21.5' iMac in target disk mode and connected it via thunderbolt with my 27' iMac but it doesn't see the 21.5' iMac while in target disk mode. They allowed M1 Macs to be gimped and did not prioritize multi display support. I am quite unhappy that this appears to be apple purposefully rendering old products obsolete by not including backward compatibility software/code. So I did some extra troubleshooting to try to target why TDM won't work. They disabled Target Display Mode so people cant use high quality Mac displays as external displays anymore.

I am using a brand new 2020 MacBook Pro, USB-C to Thunderbolt adapter, Thunderbolt cable, plugged into the iMac's Thunderbolt port (not mini display). To use the new iMac as a monitor, it must enter target display mode, which appears to happen automatically when the correct DisplayPort cable is plugged in. doesn't matter what kind pc you're using, if the imac is in target display mode it's just a monitor ( that's using a lot of power from the wall tho) No, it does not work if the iMac is in Mojave or later.

Target display mode not working, I want to set up an old iMac (mid-2011 running High Sierra) as an external monitor for my new 2020 MacBook Pro (running Catalina). An Apple support page describing the feature, dated March 2017, also states that 'iMac (Retina 5K, 27-inch, Late 2014) and later iMac models can't be used as Target Display Mode displays. Use your iMac as a display with target display mode.
