GitHub is all about collaborating. Two or more people can each have their own local copy of a repository, which they both sync to the same remote copy.

A note about Sync in GitHub for Mac

Those that are already familiar with Git may notice that there are no "Push" or "Pull" buttons in GitHub for Mac. Instead of bringing in new changes from the remote copy with one command and pushing your unpublished commits with another, GitHub for Mac uses a single "Sync" button that quickly completes both operations at the same. Behind the scenes, we do the equivalent of a `git pull --rebase` (but make sure to never rewrite merges).


In order to sync local changes to a remote repository on, you will need read & write permissions for it, otherwise known as 'push & pull' permission.

The easiest way to get push & pull permission on an open source project is to first "fork" it from to your own account.

Let's check out the following open source project called Spoon-Knife:

This project is by a user named octocat, and we want to make our own changes to it. Fork it to your account by clicking the "Fork" button for this repository.

Once you have forked your own version of this repository you will need to clone it to GitHub for Mac, so that you have a syncable, local copy.

  1. Go to your account on and select the forked repository. The URL should look like this (where my-username is replaced with your GitHub username):
  2. Click on the handy "Clone in Desktop" button to launch GitHub for Mac and start the clone.

  3. You'll need to select a folder on your Mac to store the local copy, so just select a suitable location and click "Clone".


Congratulations! You now have your own forked version of an open source project, cloned and synced with GitHub for Mac. You're ready to start contributing!
