I am trying to connect a 17" older imac with a newer 27" imac.....the thunderbolt cable has the same plug on both ends.....it plugs into the newer thunderbolt socket fine, however the thunderbolt socket on the older imac (with the thunderbolt symbol) is a different socket. How to get around this issue please.
The aim is to use the older imac as a second screen.
Thanks
iMac 27″, macOS 13.6
An old 2006 iMac with a Mini-DVI port, does not support being used as a display in Target Display Mode.
Only certain 2009 thru 2014 iMac models ever supported being used as a display by another Mac.
please carefully read > Use your iMac as a display with target display mode - Apple Support

Thank you....helpful.
You're welcome.
The new imac is a 2000 model with ventura 13.6.1, the older model (proposed screen) 2011 using High Sierra .
What year mode is the new iMac...?
In theory this may work,
Won't work if the new iMac is newer than a 2019 or running anything after macOS Catalina.
but the different thunderbolt cable connection seems to be an issue.
The 2011 iMac has a Mini DisplayPort and the newer one ??? most likely has Thunderbolt/USB-C
Also, please note that iMacs ARE NOT external displays for other devices. They are computers!
If you need an external display, please simply buy one. Why,

Do you mean a 2020 model or newer? It can't be a 2000 model.

Apologies ....typo error should be 2020. THanks.
It looks like the two imacs cannot be connected.....problem now solved with an old "Chimei" monitor from my store tried, tested and working fine. I now have a spare USB4 cable as well for a future use no doubt.
