Dear @vkucera, I won't from next time.
Since, the build/O2Physics/o2/macOS-arm failed for that PR twice. So, i tried to do it freshly, and updated my repository with the origin, and that resulted in closing the previous commit. So, i opened this one again.

You still have two warnings.

It's fine to update your repository but it is always possible to update the current pull request.

Dear @vkucera , I will fix these two warnings in the next commit.

Dear @vkucera, yes but I used this 'git reset --hard upstream/master'. It updated my local repo with the original O2Physics.

Well, that is obviously a wrong way to do it. This command makes your current branch identical to upstream/master.

Dear @vkucera, i was thinking that the macOs build error in my PR appeared due to some mistake on my side (all other PRs opened before and after mine passed that, although the error was not related to the code which was changed in my PR). So, i wanted my repo to match the original O2Physics, and then retry the commit, and was hoping that the build error gets resolved.
