title: CFData vs CFString
body: <p>I have a <code>CFMutableDictionaryRef</code>, part of which in debugger is:</p>
  <blockquote>
  <pre><code>&quot;device-id&quot; = &lt;72270000&gt;;
  
  model = &lt;474d4120 39353000&gt;;
  
  &quot;vendor-id&quot; = &lt;86800000&gt;;
  </code></pre>
  </blockquote>
  <p>Now I can get value of the key <code>model</code> using <code>CFDataRef</code> which returns string like &quot;GMA 950&quot;, as compared to the value above.</p>
  <p>But I cannot get value of <code>&quot;vendor-id&quot;</code>using same method so I try with <code>CFString</code>, which returns <code>&lt;86800000&gt;</code> instead of a string. So how to retreive correct value of the vendor id (which I already know should return 0x8086 for Intel) ??</p>
