Earlier I did try mouseDown:, and it did capture all the clicks (which
is what I wanted), but I was not sure on how to implement it. How
would I override it so that clicks would not pass through to the
superview?

I have a transparent black NSView that I layer over my window using

superview underneath. I've already tried returning NO for
acceptsFirstMouse
and it has no effect.
-acceptsFirstMouse: (note the colon) has nothing to do with this.
That determines whether clicking on the control when the window is not
main will cause the event to be dispatched to that view or if it will
simply be dropped on the floor when the window activates. Typically,
UI controls that could cause destructive changes (like a Delete
toolbar item) return NO, whereas non-destructive controls (like the
toolbar show/hide widget in the titlebar) return YES.
Have you followed Mike Abdullah's advice and overridden -mouseDown:?
The documentation for this method describes exactly why you are seeing
what you are seeing. In fact, I would have expected that to be the
first thing you would have tried. If it wasn't, maybe it's worth
seeing if the documentation can be improved to nudge people in this
direction in the future.
