Ever since I updated the OSX (V 10.9.1) iCal can't be used, when I open it a message pops saying: The server responded with an error, couldn't move calendars to iCloud because an error occurred. I turned off icloud and the same keeps happening.
Mail is not functioning right, as well as iWorks. And everything started to break down since I updated the OS 😟 please help!
