"To not show a disclosure triangle, override -frameOfOutlineCellAtRow:
and return an empty rect. You will also want to not allow it to be
collapsed by returning NO from the delegate method -
outlineView:shouldCollapseItem:. When the disclosure triangle is not
shown for a section header, the item will automatically be unindented. "
I realize the release notes are rather long, but they are a good read.
Especially for controls/components that you use.

You need to subclass NSOutlineView and override

returning NSZeroRect on a condition that makes a group a group in
your app or returning [super frameOfOutlineCellAtRow:row] if not a
group. Mine gets the represented object of the item and checks the
node's name.
