1.Remove existing files from the repository:

find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch

2.Add the line

.DS_Store

to the file .gitignore, which can be found at the top level of your repository (or created if it isn’t there already). You can do this easily with this command in the top directory

echo .DS_Store >> .gitignore

3.Then

git add .gitignore git commit -m '.DS_Store banished!'
