Pages won't open after unexpected shut down I have OS X Yosemite v. 10.10.5.  After an update about 6 weeks ago Pages started refusing to respond, then shutting down unexpectedly.  Today Pages will not open at all.  I get the error message that Pages has shut down, do I want to reopen or report but reopen doesn't work.  Any suggestions??
I'd try clearing the saved state files.

From Finder:  


 Cmd ⌘   N   
 Cmd ⌘   Shift ⇧     G      
Copy/paste ~/Library/Saved Application State


Find the folder com.apple.iWork.Pages.savedState and delete the contents not the folder itself, as it's an alias.
That should give Pages a fresh start.
