I have not been able to find any functionality in NSView that corresponds to the carbon ValidWindowRect call, which marks a rectangular area as not needing to be redrawn.

You won't be able to do this with AppKit directly. However, if there's a way to determine when your application objects are "done" invalidating and re-validating, you can implement your own system to track which rectangles should be updated. Then when the validations are complete, you can invoke -[NSView setNeedsDisplayInRect:] on your window's content view with an appropriate set of rectangles.
