Installed on an Apple Macintosh, "Parallels Desktop 5.0 for Mac" makes the software run for Microsoft Windows XP, Windows Vista or Windows 7 and Mac OS X on the same Apple Macintosh. A Macintosh user therefore also has access to Windows programs that are not offered in a separate Mac version, including Outlook, Access or Quicken.
With "Parallels Desktop for Mac", the graphics power of the Apple Macintosh is also used for PC games and 3D graphics programs. The Multi-Touch trackpad familiar from the MacBook also works with Windows programs, as do the Active Corners, Expose and Spaces utilities from Mac OS X, and the Apple remote control for controlling Windows software on a Macintosh.
The operation of "Parallels Desktop for Mac" requires an operating system from Mac OS X 10.4.11 (Tiger) and an Apple Macintosh with Intel processor. The software does not include a license for Microsoft Windows. A variant of "Parallels Desktop for Mac" is the free Parallels Mobile to start or hibernate a virtual computer with Windows XP, Vista or Windows 7 from an Apple iPhone.
