I remember a time when this mattered in terms of branding (Mac OS X being a Unix). It meant that the OS was “industrial-class”. This was against a backdrop of Macs not being seen as serious machines, unlike Windows machines which were more “corporate”.

But nowadays macOS is so pervasive that a Unix certification doesn’t buy much brand cachet. Perhaps it might help for specific compliance requirements but those are likely the minority.
