If you are bored with the default Microsoft Windows XP, Vista, 7 and 8 theme layout design, why not skin your Windows to look like Apple’s Mac OS X Yosemite? Yosemite Transformation Pack 2.0 will transform your Windows 8.1/8/7/Vista/XP user interface to Mac OS X Yosemite, including OS X Yosemite Boot Screen, Login Screen, Themes, Icons, Wallpapers, Sounds, Fonts, Dock, Dashboard, Spaces, Launchpad and more.
As shown in the screen shots above, the Windows user interface is transformed into a Mac OS X user interface. Download Yosemite Transformation Pack (YTP) v2.0 (103MB). Do understand that if you have a very slow computer, using this skin will probably cause it to slow down or lag badly. make sure you have enough RAM to support this skin.

If you really love the Mac layout, my advice is to buy a Mac. Get the real deal.
