Same here. I’m least familiar with macOS compared to Windows and Linux, but the uninstall story on Mac was always baffling to me.

On Windows, it’s not perfect because it’s ultimately cooperative, but at least the developer of the application can also configure how it should be uninstalled. If you mostly stick to “reputable” applications, you know they would have gotten so many complaints about random things they leave behind that they slowly fix their uninstaller. Also you usually get the option to completely uninstall or keep data files, etc. Though it’s not universal. Uninstaller apps like CCleaner used to be more popular, but I hardly hear about these things anymore and usually advise against them.

On Linux, the story is slightly better as you rely on your distro package maintainer to configure the right uninstall logic. Removing random config files in /etc/ or data files in /var/ or systemd units, etc. Usually maintainers get it right as long as you stick to those feeds, and when something is missed it’ll get fixed eventually.

On Mac it seems to be either google it to get a list of locations to clean (which is what I do), or just delete the folder and ignore the random files or use CleanMyMac ($19.99) or CCleaner ($12.99) or MacAppBeGone (that’ll be $8.99) etc. luckily you can try to stick to homebrew and the App Store, but it’s limiting.
