BSD Is a B S D Based Eunuchs System.

Macos is actually b s d eunuchs. It's based on darwin, which is a sort of port. There is no bsd, eunuxh darwin living behind the scenes if you're on a mac,. Unless you really want to really dig for it. And that was the big thing with macos. So all these different operating systems have these different tools that you use that allow you to just install stuff. In some cases, like homebre, we'll do this for you.
