after executing opam init -y. does i do something wrong or its just a ocaml / opam problem ? Have a good day

Do you happen to have something like binutils or gcc installed via brew in your PATH ? If that's the case that may be the problem. Issue either of (assuming you are using brew):

brew unlink bintutils
brew unlink gcc 

and try again.
