Drag the SketchUp icon and Drop it in the Applications folder to copy the application to your computer.This will mount the installer drive and open a window with a SketchUp icon on it. Locate and double-click on the Installer file (DMG file, probably in your Downloads folder).Tip: You may also want to remove any existing SketchUp icons from your dock from previous versions (Right-click on the dock icon > Options > Remove from Dock), to avoid version mixups.
