title: SourceTree on MacOSX Sierra 10.13.x : Permission Denied at each laptop restart
body: <p>I use SourceTree with Bitbucket. Since the last updates of my MacOSx there is this error at each time I restart my laptop (when I want to push my code to my Bitbucket account of course):</p>
  
  <pre><code>git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree push -v --tags origin refs/heads/develop:refs/heads/develop 
  Pushing to git@bitbucket.org:xxx/mobile-android.git
  git@bitbucket.org: Permission denied (publickey).
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists.
  Completed with errors, see above
  </code></pre>
  
  <p>How can I do to avoid this at each restart? This problem is here since 10.12 Sierra OS version.</p>
  
  <p>** UPDATE</p>
  
  <p>Currently, I must do that at each restart:</p>
  
  <ol>
  <li>Remove all keys in .ssh folders</li>
  <li>From SourceTree remove the last connection, and create a new connection linked with my bitbucket account</li>
  <li>A new key is automatically created by SourceTree</li>
  <li>I copy it and I paste it on my Bitbucket settings account</li>
  </ol>
  
  <p>Now, It's ok. But I can't understand why I need to do that now at each restart...</p>
  
  <p>Thanks for your help guys!</p>
