If you have a shared Git repository on a shared directory on a multiple user Mac
and you cannot edit anything because the repo belongs to the other user,
you can fix that by:

First, grant yourself the permission to all files (recursively):

```shell
cd <YOUR-SHARE-GIT-REPO-PATH>
sudo chmod -R 777 $(pwd)
```

Now your (stupid) Git client app showing all the files as edited, just have the courage to reset (hard).

```shell
git reset --hard
```

Do the same thing to every submodule.

```shell
git submodule foreach 'git reset --hard'
```

Btw, if you're not a Mac admin user: good luck !
