Parallels Desktop 5 for Mac software lets your Apple computer seamlessly run Windows programs on the Mac OS—without rebooting. Easily drag-and-drop documents, pictures and music between Windows and Mac applications, and launch your favorite Windows programs right from your Mac’s dock. If you love the look and feel of Mac OS, make Windows invisible while unleashing the full power and speed of its applications. If you're new to Mac, keep the familiar Windows background and Start Menu. If you’re a little bit of both, choose as much Mac or Windows as you need, without compromising performance.
