Not able to install 4CAT on my MAC

Hi, I hope this is the right section. After having to reset my Mac, I am no longer able to use 4CAT. I follow the entire installation procedure that I have always used via Docker, but when I try to connect to the local host and then open 4cat, nothing happens: it doesn't connect to anything.

I really don't know how to solve the problem. Please help me :)
