    Right-click (Control-click) the Parallels icon on the Mac desktop or in the Dock and choose Move to Trash or Remove from Dock, or drag the Parallels Desktop icon to the Trash.

  2. Place the upgraded Parallels Desktop icon back onto the Mac OS desktop or to the Dock.

    1. In the Finder, open the Applications > Parallels folder .

    2. Drag the Parallels Desktop icon from the Parallels folder to the Mac OS desktop or to the Dock.
