By default, Fusion selects the virtualization engine best suited to your virtual machine's operating system and your Mac's processor. You can override the automatic setting and select a specific virtualization engine. If you are not familiar with the options, keep the default setting.


  1. Select Window > Virtual Machine Library.
  2. Select a virtual machine in the Virtual Machine Library window and click Settings.
  3. Under Other in the Settings window, click Advanced.
  4. Select an option from the Preferred virtualization engine menu.
