Subclass NSClipView and override -constrainBoundsRect: to return the centered rect. This is discussed at the the 45:30 mark in the fantastic presentation from WWDC 2013 - Session 215: Optimizing Drawing and Scrolling on OS X

Use an intermediate NSView which has the document view centered in it (set its frame accordingly and probably set layout constraints the way it should behave). Put that view in the scroll view.
