@sanchit122006 are you posting unreviewed tooling / AI output here? E.g.

• This has nothing to do with subprocesses and windows:

  Fix macOS CI: remove redundant brew update and add coverage file check

• There are a lot of formatting / style changes, which totally obscure whatever logic might be here
• Why are there code/docstring screenshots without explanation?

This is not acceptable. I put the PR in draft state for now. Please cleanup and make sure all content (code and PR message are presented in a clean way). When you think the content is suitably consolidated so that it's worth putting valuable core developer time into, you can remove the draft status.

@timhoffm Can you guide me to solve cl check's issue ,
macos cl, whitespaces and iteration's commits is for solving command line check failing issue of this PR ,
should i not commit the changes i made in action files to solve command line issue?
could checks passed by only saving the file and not commiting?

What exactly is "command line check failing issue"? Are these failures in your local setup, e.g. pre-commit?

Generally, a PR should only contain changes that are related to the PR. If for example, I very stongly assume the brew update change is independent of this PR. If you think a such a change is reaonable (or even prerequisite but independently meaningful) , please open a separate PR. It's much simpler to handle logically independent change separately.

@timhoffm i am talking about these checks, can you guide me should i make new branch and PR on it, because 1 test is failing yet before has 2 failing checks then i edited and commit to fix macos check

Unfortunately, this is another unrelated flaky behavior: #30882. You can ignore this for the scope of this PR.

Likewise the osx issue is unrelated to the PR.

e.g. both have also occured in #30600.
