If you receive an error message on Chrome when you try to download apps, themes, extensions or other files, try these fixes. You could use the direct link to download xcode from the Developer Center: It's not an unknown error, we totally know what it is. it while I'm working and my failed attempts were when I left the mac idle while it is downloading to open activity monitor, double-click the AppStore process, and select "open files and ports".
