Before I bought my new MacBook Pro M1 Max, I had MacBook Pro (Early 2015). I used my iMac (27-inch, Late 2013) as a target display mode for my photography work. I used thunderbolt to thunderbolt cable based on this article
I used to press Command-F2 on the keyboard of the iMac and I would see the desktop of my MacBook Pro. But, I am not sure how to make the same setup work for my new MacBook?
I have tried to connect through HDMI cable, it didn't work. I ordered USB-C to Thunderbolt but I received Thunderbolt-3, that didn't work. I also tried Display Port to USB-C, it didn't work either. Only thing left to try is USB-C to Thunderbolt-1 cable, but I am not finding such cable.
Any idea how can I make this work, I don't want to loose my iMac. Appreciate any help and links to the cables that I should work with.
This YouTube video made 2009 iMac work with M1 laptops - so I am sure, there is a way for 2013 iMac IMHO.
