I don't see how the current MacOS is any different from Linux there. For end-user applications you can have the user download an app bundle (equivalent to AppImage) or get it off the app store (equivalent to flatpak/snap). For random open source libraries and utilities, you still would want to use Brew or Macports, which are package managers.

It's been a while since I've used a current (post-MacOS9) Mac. It used to be the case that the vast majority of applications were Application Bundles.

I do just fine with macOS UNIX userspace.
