title: Change MacOS X guest screen resolution for VirtualBox
body: <p>I have tried all alternatives and resources that I found on internet to achieve to change screen resolution in my MacOS X guest. I have the latest VirtualBox version (4.1.22) and I have MacOS X 10.6.3 Snow Leopard running in a vm guest.</p>
  
  <p>Some solutions that don't work for me are:</p>
  
  <ul>
  <li>Tuning virtual machine settings:</li>
  </ul>
  
  <p>Adding  and  in the .vbox file, or running these two commands: </p>
  
  <pre><code>vboxmanage setextradata "MAC OS X" "CustomVideoMode1" "1360x768x32"
  vboxmanage setextradata "MAC OS X" "GUI/CustomVideoMode1" "1360x768x32"
  </code></pre>
  
  <ul>
  <li>Editing Guest OS boot configuration:</li>
  </ul>
  
  <p>Modify /Library/Preferences/SystemConfiguration/com.apple.boot.plist with these lines:</p>
  
  <pre><code>&lt;key&gt;Kernel Flags&lt;/key&gt;
  &lt;string&gt;"Graphics Mode"="1360x768x32"&lt;/string&gt;
  &lt;key&gt;Graphics Mode&lt;/key&gt;
  &lt;string&gt;1360x768x32&lt;/string&gt;
  </code></pre>
  
  <p>Any other suggestion, something that I was missing.</p>
  
  <p>Thanks in advance,</p>
