> All macOS is is just a different window manager
This dramatically undersells what MacOS is and was. It was way beyond just a window manager.
From its inception in the 1980s it included a set of APIs that allowed developers to build sophisticated (and consistent) GUI applications with comparatively little effort. eg Quark Xpress, Illustrator, Photoshop, Excel, Word
By the end of the classic Mac era in the late 1990s that API set had grown to include a ton of stuff. QuickTime, ColorSync, TrueType, AppleShare, sophisticated printer support, multiple display support, etc
Like any proper desktop OS from the 16 bit days that got their inspiration out of Xerox.
It is only on UNIX land that is a mess, the only thing that people have managed to agree on are POSIX, and Khronos APIs.
