> Technically OS X is a "UNIX clone"

Yes it is, but it doesn't share the UNIX culture, rather the GUI culture inherited from the Xerox PARC ideas that impregnated Apple and NeXT.

The UNIX compatibility was a requirement for NeXT to get a foot in the market targeted by Sun and Irix workstations.

Apple and NeXT never had a culture of pure CLI applications and daemons.

Recently I familiarized myself with Qt, that is often presented as core windows/linux framework. Half of linux apps is Qt. Years ago I also knew GTK+ 2.x very well. The other half is GTK. From developers perspective, Cocoa+AppKit/UIKit are orders of magnitude more powerful and conception-rich, and that is easily seen in UX, once you get base skills in it (i.e. stop believing 'it cannot do that', because 'it' mostly can).

Technically, macOS is UNIX, not a "clone".
