In theory, Homebrew should solve this, but I’ve just had so many bad experiences with it over the years, I won’t touch it. All the problems you can imagine from trying to tell a non-techy friend over voice, without screensharing, how to do all that stuff you just listed? Brew seems to make those same mistakes half the damned time, and leave your system / the app in a weird, half-installed state. It seems like most app devs have come to the same conclusion and just make actually good installers. It’s unfortunate that it’s come to that, but there ya go. I honestly have no idea if that’s a Homebrew problem or if it’s just doing its best with what apple gives it to work with, but either way.

I’ve had better experiences with Chocolatey on Windows, but for casual / everyday use it’s just so rare I need to install something that doesn’t have its own nice installer, so I very rarely run it.
