Things you will need:
Mac Computer (MacBook Air, MacBook Pro, MacPro, iMac) Valid Copy of Microsoft Windows 7, 8, or 8.1 Valid Copy of VMWare Fusion or Parallels Workstation for Mac. ( I prefer VMware Fusion and is what i will use in this guide) Latest FreeStyler Build from www.FreeStylerDMX.be USB DMX Adapter (or ArtNet DMX Adapter)
As an Alternate, you can use the Free Virtual Box software from Oracle instead of VMware Fusion (https://www.virtualbox.org/wiki/Downloads)
Some notes to keep in mind, You will need to Assign your Virtual Windows OS at least 2GB of ram. Make sure your MAC has at least 4gb. 8gb is recommended.
