I've used Macs professionally and Lawrence is right. Many (not all) applications are in fact self contained apps (which are just folders with executable + Metadata + resources)

Dude I've shipped two commercial games onto Macs...

It is certainly possible to do things more cleanly on MacOS than on Windows. My point was that the "drag to Applications folder" is not a bare copy; it runs installers if present. (You can get away without them for now; you can do that on Windows too, it's just much harder,

and starts to become impossible depending on what you link with. MacOS is going down that same road, it was just cleaner for longer).
