The battle PC vs. Mac, with the hilarious ads intended to show virtues, advantages and disadvantages of both systems needs not to be part of our daily work. It is not always easy to decide which system is the best for us, and this usually happens in big companies, where some IT people prefer Mac and some others prefer PC...and the poor employee has to adapt to the management's likes and dislikes, with the consequent compatibility issues that may arise, especially if we have to move from PC to Mac all of a sudden and we need to carry our windows system with us.
But to make our lives easier, Parallels brings to us Parallels Desktop 4.0, a sophisticated system able to mount several virtual machines on a single Mac, be it Windows, Linux or any other operative system with its particular applications. And it achieves this by introducing a middle layer between the Mac and the guest OS.
Make The Most of Every OS
This award-winning hardware emulation virtualization software really simplifies the joint use of apparent antipathetic OS.
Something great...with Parallels Desktop on your Mac you do not need to worry about which OS you are using, since the SmartSelect function lets you open Windows files with Mac applications and Mac files with Windows applications...amazing ductility, isn't it?
Windows
Windows programs can be opened as if they were native Mac applications through Coherence. And it also brings the top model of graphical user interface world: the drag and drop function.
Get Virtual
Parallels Desktop is an excellent virtualization software for Mac OS X, which allows you to run a Windows environment with Mac in a window to window view, in the same desktop without rebooting in order to switch between them.
The newly arrived, Parallels Desktop 4.0 for Mac, has significantly improved its performance running Windows, compared to its previous version, reaching between 40% and 50% improvement.

Version 4, the first new version of the software in about a year, includes new manageability features that enable users to more easily manage external storage devices, and create backups for data protection.
Parallels Desktop for Mac Version 4 includes an adaptable Hypervisor to automatically optimize performance based on running applications on the Mac at any time. Earlier versions of Parallels had a switch to optimize performance in the Mac environment or in the guest operating system. With the new version, Parallels automates the process right away, placing resources in the environment in which the most demanding applications are being run, both in the native Mac environment as in the virtual machine.
