Do you delete leftover files after deleting an app or just let them be?

I've been using TrashMe and sometimes AppCleaner for a long time. Both work quite well.

I use AppCleaner, but will also use "EasyFind" to do a manual search sometimes, as well.
(example of the latter -- getting rid of old adobe "FlashPlayer" files)

Remove-It does a great job of removing all traces of an app. Inexpensive too.
Remove-It fails to find all of its own files :)

It's probably a good practice, but I personally don't care and never do it intentionally. On my list of priorities the importance of deleting leftover files is somewhere below zero. Not saying that's the right policy, but since you asked...

Yes. I used to use that app zapper app long time ago that removed the prefs also. But I prefer to do it manually.

Just be careful what you delete.

And if you do accidentally delete prefs and support files permanently it can be rebuilt by the app next time.

DO NOT ever use file recovery apps that promise to recover deleted files. All of these apps I have seen are malignant and over promise. They try to install themselves deep into the system and pressure you to pay money for them to "work better". They cannot work better. It is almost impossible to recover deleted files on SSDs that use TRIM.

Why isn't such an uninstaller built into macOS?

In addition to already mentioned technical reasons, I'm afraid there's simply no sufficient demand for this (which doesn't mean Apple would do this if the demand was actually there, of course). Third-party apps mentioned here already serve well those users who wish to delete leftover files.

I use EasyFind and do it manually. It's actually hard to screw up when using the date created column.

Is there any "harm" in leaving leftover files where they are after uninstalling an app? I assume these leftover files literally do nothing other than take up a little storage space?

This really depends on the app itself. All junk files will take up space, but some apps have Safari Plugins and Extensions or even network extensions integrated into the macOS, so it's possible there's some kind of impact if you were just drag the app to the trash instead.

For apps that have a built-in uninstaller, do you use that or still prefer to use a third-party "cleaner" app or some other manual method? Basically, do the built-in uninstallers that some apps have, do they also leave some leftover files behind?

New app - Pearcleaner https://github.com/alienator88/Pearcleaner

I haven’t tested it yet, but it seems to be good at removing a lot of Brave garbage :)

I use AppCleaner, and have for years, but it still doesnt get everything. After I run it I will still look for left over files, and on occasion find some.

where do you look?
i usee appcleaner too.

Another for AppCleaner, simple, easy & free. I run it's background daemon so when an app if dropped in the trash AppCleaner automatically detects all related files and advises. For anything really stubborn I use Find Any File, which is rare. It can manually remove pretty much anything with extreme prejudice LOL...

The one thing I like about TrashMe is that it shows specifically the folders associated and if it can’t delete folders or files because of permissions, it will tell you.
