Before, to be able to have several operating systems at our disposal, it was necessary to partition our hard drive (a relatively dangerous task) and quarrel with configurations. Now, VMware Fusion allows us to virtualize any operating system inside Mac OS X. Windows, Linux Novell or Solaris can be virtualized easily, as VMware Fusion is compatible with more than 140 operating systems. This means we can have any OS ready to go without even rebooting our computer.
The task of virtualizing basically consists in emulating a computer inside another one, with its own operating system installed. The virtualization performed by VMware Fusion is so refined that it even allows us to emulate DirectX 9 with its advanced 3D possibilities.
Furthermore, VMware Fusion can be totally transparent to the user, launching just about any Windows application on a Mac as if it were a native application.
VMware Fusion is compatible with the latest Mac systems, with multicore processors and 64-bit support. It also integrates with Exposé, the dock and Boot Camp without any problems.
