title: Github Mac Permission Issue
body: <p>I'm using the latest Github for Mac as a new Git user. When I try to sync a repo (that I first cloned, then created a new branch, commited changes, and then merged with master), I got the error:</p>
  
  <pre><code>Authentication Failed.
  
  You may not have permission to access repo111. Check Preferences to make sure you’re still logged in.
  </code></pre>
  
  <p>I searched for similar questions, but the answer seemed to be add SSH keys to github, so I followed: <a href="https://help.github.com/articles/generating-ssh-keys">https://help.github.com/articles/generating-ssh-keys</a>.</p>
  
  <p>When I do <code>ssh -T git@github.com</code>, I get:</p>
  
  <pre><code>Hi User111! You've successfully authenticated, but GitHub does not provide shell access.
  </code></pre>
  
  <p>I'm logged in as the correct user, and have rights to the repo, so I'm not sure why I'm not authenticated?</p>
