title: Pygame window not showing in MacOSX
body: <p>I've been using pygame inside a conda environment. The installation went well, but whenever I call flip, it doesn't open any window from the terminal.</p>
  
  <p>Here's the code that's supposed to open the window:</p>
  
  <pre><code>screen.blit(background_image, (0, 0))
  pygame.display.flip()
  pygame.display.update()
  </code></pre>
  
  <p>After pygame starts, it shows this message:</p>
  
  <blockquote>
    <p>WARNING:  140: This application, or a library it uses, is using the
    deprecated Carbon Component Manager for hosting Audio Units. Support
    for this will be removed in a future release. Also, this makes the
    host incompatible with version 3 audio units. Please transition to the
    API's in AudioComponent.h.</p>

  <p>Here's the <a href="https://github.com/cleytonmessias/AIND-Sudoku/blob/master/PySudoku.py" rel="nofollow noreferrer">entire code</a>.</p>
  
  <p>It's a sudoku game that should display a board with Sudoku being solved.</p>
