Keynote, Pages, and OmniGraffle can do this – but, especially Keynote and Pages, getting the lines between boxes right is fussy and time consuming. If you insist on “native” then go with OmniGraffle – but don’t pay for a license if this is a one-time use case. Lucid is fine, but expensive.
Best price, and pretty good feature set for org chart and numerous other templates is draw.io, which has the online and a desktop app for free. Why’s it free? Who cares. It works.
