Mac & PC enthusiast you can run multiple operating systems on your Mac or PC in a Virtual Machine from Parallels Desktop for Mac, or Parallels Work Station for the PC.
Both Parallels titles allows you to run a Windows OS system and software inside your Mac or PC. This is sooooo cool to use!
So, if you’re running a Mac or a PC and you need, say Windows 7, or Windows 8 , 8.1 or even a Linux system that you like to use you can have the best of both worlds.
