Share Your Code with GitHub for Mac
GitHub for Mac has just launched recently. Now you can Clone repositories, Browse history, Commit changes, Branch code, and Share code on github.com as simple as possible. The sync button pushes your changes to GitHub and pulls down other’s changes in one operation.
You can add a repository by dragging a folder to the application. When you add repositories to GitHub for Mac, they automatically match them up with any organizations you belong to.
