We have covered the Mac transformation pack for Windows 7 which was very neatly written transformation pack which brought in the look and feel of Mac OSX to Windows 7. The transformation pack modified many system files, but the new Mac themepack for Windows 7 (Windows and Mac United) is easy to use theme file which brings in the look and feel of Mac on Windows 7 without effecting the performance or system in any way.
The best part of the theme is even being a themepack, it does the modification pretty neatly. The Windows explorer has a pretty good looking OSX style skin and also there are some sound schemes based on Mac. The theme pack comes with 5 wallpapers.
