Oddly enough, my favorite package management experiences, by far, have been Homebrew on Mac and Portage on Gentoo. Talk about polar opposites.

I do think, unfortunately, that the experience of a very stable base of macOS with Homebrew on top would be nearly impossible to replicate on desktop Linux, because Linux's GUI layer is so intertwined with user software, and is so... uh, "free and libre", I guess, is a nice way to put it. You'd end up with a bunch of copies of KDE and Gnome libs and probably multiple competing IPC buses or god knows what, in no time. Maybe multiple sound daemons stepping on each other. You'd probably have issues like different apps deciding to do scaling or font rendering differently, or who knows what, because lots of "basic features" on macOS are instead choices on Linux.
