While Life Tributes does not run natively on Mac OS X, you are able to run Life Tributes in a virtual machine. Both VMware Fusion and Parallels allows you to run a virtual Windows computer inside your Mac-based computer.
VMware Fusion: http://www.vmware.com/products/fusion/
Depending on the version of Windows you install on your virtual machine, we suggest having no less than 2GB allocated to the image to make sure you get adequate performance. We also suggest consulting with your local computer technician or our technical support department to see if your Mac has adequate system resources to run virtualization applications properly.
While most Windows applications work well within a virtual machine, we cannot guarantee results due to the driver sets and services that virtual machine platforms provide. .
