You can install OS X Server or OS X Client in a virtual machine. VMware Fusion creates the virtual machine, opens the OS X installation assistant, and installs VMware Tools. VMware Tools loads the drivers required to optimize a virtual machine's performance.

VMware Fusion-created OS X virtual machines can run on any Apple-branded hardware that uses Intel processors. The Apple licensing agreement defines the situations when it is permissible to virtualize OS X. VMware Fusion does not change these terms or enable OS X on non-Apple hardware. You cannot use a Mac OS virtual machine in another VMware product, like Workstation.

VMware Fusion supports the following:

Mac OS X Server 10.5, 10.6, 10.7, 10.8, 10.9

Mac OS X Client 10.7, 10.8, 10.9

VMware Fusion does not support the following items:

drag-and-drop between host Mac and guest Mac

multiple displays

3D Accelerated graphics

Unity Mode

To install the operating system, use the procedure for creating a virtual machine for any supported operating system. See Create a Virtual Machine for Any Supported Operating System.
