Thunderbolt display 27" not working on catalina and macbook pro 16"

I recently bought the thunderbolt display and I am using it with thunderbolt 3 to 2 adapter (original apple). When I plug it into the display nothing happens.

I am using Catalina 10.15.6 on macbook pro 16"


I tried to connect it to an old macbook running older version of macos having a thunderbolt 2 port the display works fine which proves that the display is working but when afterwards when i connect it to my macbook (using the adpater) it magically starts working until i shutdown my mac and check it the next morning it doesn't wakes up.


So i believe it somehow gets triggered when i use it on older mac.

I have repeated this a couple of times and it works fine.


I believe there is a problem with the macos Catalina.


Any solutions?


MacBook Pro 16″, macOS 10.15
