VMWare Fusion

The seamless way to run Windows, Linux, and other PC operating systems on your Intel-based Mac, VMware Fusion gives you the freedom to run Windows and Mac applications side by side on your Mac. They operate inside a secure and isolated virtual machine, protecting your Mac from any Windows crashes or instability. You can find and launch Windows applications quickly with the VMware Fusion launcher. Or switch between Windows and Mac applications with Expose. You can even minimize Windows applications to the Mac OS X Dock.
