You responded to “macOS is UNIX” with “it’s not open source”. I’m just illustrating how these 2 things are not correlated.
In any case, macOS is based on OpenBSD. Even the original BSD, which OpenBSD is based on, was not initially open source.
Everything you said was a straw man.
I wouldn’t want your help anyway, considering you think your reading comprehension is better than mine. 😆
