The product can be installed and set up easily. It is stable and has very extensive possibilities for various virtual machines. I use it with Win 7 on a Mac with Mountain Lion and now Mavericks as OS. Through the Parallels V9 upgrade now runs everything perfectly with my MacBook Pro Retina hardware. Essential to my recommendation is the really striking stability of the product. It is neither in the operation of Windows, even Mac OS X in the last 2 years (with version 8 or 9) problems occurred, although I often work in Coherence mode, run "criss-cross" in the applications of both operating systems. Through Parallels can use the most appropriate applications of "both worlds". So really great is that if you have additional "NTFS for Mac OS" installed, because then you can simply continue to use the contents of his old PC sheets as if "would be nothing".
