When developing with Git on macOS, you may find .DS_Store files unintentionally added to your repository. These files are specific to macOS and unnecessary for your project. This article introduces effective methods to solve this issue.

What is .DS_Store?

.DS_Store (Desktop Services Store) files are hidden files used by macOS Finder to store folder display settings. These are unnecessary for project version control and can be noise for users of other operating systems.

Solution Steps

1. Create a Global .gitignore File

First, let's set up a global configuration that applies to all Git projects.

cd ~
echo .DS_Store >> .gitignore_global
git config --global core.excludesfile ~/.gitignore_global

This creates a .gitignore_global file in your home directory and applies it to Git's global configuration.

2. Update Project-Specific .gitignore File

Next, configure individual projects to ignore .DS_Store files. Add the following to your project's .gitignore file:

# macOS
.DS_Store

3. Remove Already Tracked .DS_Store Files

If .DS_Store files have already been added to your repository, you can remove them with the following commands:

find . -name .DS_Store -print0 | xargs -0 git rm --ignore-unmatch
git commit -m "Remove .DS_Store files"

Conclusion

By implementing these steps, you can effectively prevent .DS_Store files from being included in your project's version control. This setup allows macOS users to work in a cleaner Git environment and facilitates smoother collaboration with team members using other operating systems.
