Run Windows (and DOS and Linux and OS/2 and BSD) on your Mac with VirtualBox
No longer are PC and Mac users stuck with only the operating system that shipped with their hardware. Users have several choices of virtualization software that allows them to concurrently run a virtual guest machine with the same or a different operating system from their host machine. A relatively new and popular use for virtualization is to allow Intel Mac users to run a virtual Windows machine without having within OS X, providing users access to Windows only applications.
