title: How do i implement section in core data for mac?
body: <p>iOS provides <code>NSFetchedResultsController</code> class with sectioning support:</p>
  
  <pre><code>     NSFetchedResultsController *aFetchedResultsController =
                   [[NSFetchedResultsController alloc]
                               initWithFetchRequest:fetchRequest
                               managedObjectContext:self.managedObjectContext
                               sectionNameKeyPath:@"CtoP.title"
                               cacheName:nil];
  </code></pre>
  
  <p>Core Data for Mac OS X doesn't provide an equivalent.</p>
  
  <p>How can I implement sections for calendar days in my custom <code>NSTableView</code>?</p>
