title: Install wxPython on Mac os Mavericks
body: <p>I am on a Macbook Air, running Mavericks. Today I downloaded wxPython via their website, however, when I click on the install package I get:</p>
  
  <pre><code>wxPython3.0-osx-cocoa-py2.7.pkg” is damaged and can’t be opened. You should eject the disk image.
  </code></pre>
  
  <p>Anyone have any ideas to get around this, thanks. </p>
