Default git branch name is master not main on MacOS

[songyang-dev]

Problem

On MacOS Sequoia 15.0.0, cargo init will create a project with git initialized but the default branch name is "master" instead of "main".

Steps

1. Install the latest Rust toolchain on MacOS Sequoia 15
2. cargo init an empty project
3. Check the default branch name with git status.

Possible Solution(s)

Manually modify the name of the branch.

Could you try git init and see which branch name it creates? You might also like to check in your fit config files the init.defaultBranch value.

This seems like an upstream issue: https://github.com/libgit2/libgit2/issues/6883.

It might be either you don't have Apple Command-line Tools installed, or they removed the default git configuration in Sequoia. Either way, this seems to be out of control of Cargo. Cargo generally respects what libgit2 does to configuration.

git init creates a main branch not master.

-> % git config --get init.defaultbranch
main

As for the libgit issue, I have a similar output.

-> % git config --show-origin --show-scope --list
