title: Genymotion, "Unable to load VirtualBox engine." on Mavericks. VBox is setup correctly
body: <p>I keep getting the following error:</p>
  
  <p><img src="https://i.stack.imgur.com/VTChF.png" alt="enter image description here"></p>
  
  <p>I have reinstalled, deleted and tried about EVERYTHING to get Genymotion to work again.</p>
  
  <p>I do not have the device I need, but Genymotion was PERFECT for the job, until Mavericks update I have been fighting to get it to work again. </p>
  
  <p>MacBook Pro, Retina 13-inch, Early 2013.
  i5, 8gb.</p>
  
  <p>I'm running version 1.3.1 for os x.
  I do have Virtualbox 4.3 installed with Oracle_VM_VirtualBox_Extension_Pack-4.3.0-89960.vbox-extpack too.</p>
  
  <p>My Virtualbox starts up normally without ANY errors.
  I tried Environment variables putting vbox on my $PATH, all sorts of things.
  Nothing works! </p>
  
  <p>I have no idea what to do anymore, anyone out there had similar problems and fixed it ?</p>
  
  <p>EDIT:
