alt Hacker News> Mac apps often do various things on your computer. Just because you dragged it to Bin, doesn't mean there are no leftovers on your computer. I'd prefer proper uninstaller any day.
I think I know what you're talking about. There are likely files inside the ~/Library/Application Support/ or ~/Library/Caches/ folders for example.
What is the proper, Apple way to make sure these get deleted when we delete apps? Because I fear there is no universal solution here. There are some files that an app creates that some of the time I would probably want to persist uninstalls. But then these files should be in a user home directory, not in application support according to XDG, right? I feel like the OS should detect dragging of an app to the trash can and clean up its app support folders? I don't think it does this today but I think it should.
It wouldn't be hard to display "remove configuration and cache files?" modal during uninstall/trashing process. But it would be hard to go against own simplicity of platform usage idea - that's the problem.
KDE's Discover after you uninstall a flatpak application shows small infobar (still really easy to miss) saying "appname is not installed but it still has data present." with "Delete settings and user data" button.
But then, all sort of software even on Windows leaves some kind of traces of own presence.
In a perfect world we'd have a standardized application uninstall procedure - either by dropping icon on trash (which is something still many people do - especially on Windows) or by bringing similar to mobile solution with "x" on longer click. All of this controllable by options for advanced users including optional configuration and cache files removal.
