I have a brand new iMac and an older one from 2012 that I want to use as a monitor. Will it work? I know that it was working from Thunderbolt to Thunderbolt but the new connector is USB C. So I should come out from the new iMac with a USB C and come into the other one with a Thunderbolt 2. Should I use an adaptor USB C male to Thunderbolt female then a Thunderbolt male-male? Or a cable USC C to Thunderbolt if it exists ?
Thank you
Marc
Didn't Apple just recently update this information to include 2020 Macs
I rechecked the article immediately before posting this and the language is the same as the screenshot--2019 and older. The last revision to the support article was April 21, 2020. One of our hosts confirmed the TDM/2020 models change last week (as I recall).
...though with the continuing restriction that the 2012 iMac must be a 27 inch model
The 2012, regardless of screen size, always worked:
Yes, the OS on the target computer must be 10.13 or older.
No-go on your new iMac doing TDM. This article tells all: Use your iMac as a display with target display mode - Apple Support
It states that TDM is only supported on 2019 and earlier Macs.
The correct connection is a Thunderbolt 3 adapter

plugged into a Thunderbolt 3 port on the new iMac and a Thunderbolt cable

from the adapter to the old iMac.
If your new iMac is more than a week old, it is the 2019 model, so should work. If it's the brand new one just announced a few days ago, then it's the 2020 model, and according to the recently updated Apple article, won't be able to use another iMac in Target Display Mode.

****'! That doesn't sound like a good news to me.
My old IMac has begun to be too slow with the latest Adobe products but the graphic card was still good, it would have been perfect as a display.
Thanx for the answer though!
Hi guys. Here is the feedback.
IT WORKS
My new Imac was older than the one just announced so it seems that it is still a 2019.
I had to downgrade my OS on the IMac used as a Target Display (I had to format and install High Sierra, it doesn't work with a newer OS)
Connect both IMAc with Adaptor USBC-Thunderbolt 2 + male-male thunderbolt 2 cable.
Cmd + F2 on the second one, and bim, Target Display is on.
Thanx for your help

What he said, sorry
Didn't Apple just recently update this information to include 2020 Macs, though with the continuing restriction that the 2012 iMac must be a 27 inch model running High Sierra or earlier?
My older IMac is a 27inches.
I guess I'll have a try anyway. Worst case scenario, it will cost me the price of the cables.
I'll let you know if it worked or not.
Thanx
Great to hear! :)
Imac late 2012 as a monitor for iMac 2020?
