Nope, still leaves them behind. I’ve been using AppCleaner ( https://freemacsoft.net/appcleaner/ ) for years now and it’s a real neat (and free) app that’ll do a pretty decent job of cleaning up crud.
This is just unbelievable. The billion $$ company cant just automate the uninstall procedure for their users? How hard would it be to auto delete the contents of ~/Library? Or have some periodic auto clean? one can always dream, no? I wonder how many users that have uninstalled VMware still have 30 gigs of unused VMs lying around on their disk.
For example on Windows if you grab a zip for an app and just put it in Program Files (or anywhere), run it then delete it there is nothing Windows does to clean up the files in AppData or entries in the registry.
Same on Linux if you grab a tar.gz, extract it to /opt and use it then delete it. All the data in ~/.config etc remains.
If the app developer providers an uninstaller it may clean up such data but that isn’t an OS feature.
There are many macOS apps that come with a pkg installer and uninstaller that cleans up in much the same way as an installer on Windows.
A little tip: if you use homebrew on macos you can use brew to force uninstall any application along with the zap argument and it will clean up most things. The app doesn’t have to have been installed via homebrew for this to work.
So if you wanted to remove Obsidian that you had manually installed using the dmg you could do `brew remove --cask --force --zap obsidian` and it will remove the Obsidian .app, plist, cache files in Application Support, etc.
You can also check the brew formula file which is just plain text to see exactly what it will remove during a zap which is quite handy.
