Scan your Library
MacSweep reads the folders where app data lives and matches every item against the apps actually installed on your Mac, by name, bundle identifier, and the helper tools apps declare.
App Leftovers
Dragging a Mac app to the Trash almost never removes everything. Caches, containers, login items, and support files from apps you uninstalled months ago are still sitting in your Library. MacSweep finds them, groups each one under the app that left it, and shows you exactly what is safe to remove.
macOS has no built-in uninstaller. When you delete an app, its data stays scattered across ~/Library: cached data, WebKit and cookie stores, group containers, saved application state, login items, and crash logs. One app can leave dozens of files behind. Over a few years of trying software and moving on, that adds up to real space you cannot see in Finder.
The usual answer is to hunt through Library folders by hand, which is slow and easy to get wrong. Delete the wrong folder and you can break an app you still use.
How it works
MacSweep reads the folders where app data lives and matches every item against the apps actually installed on your Mac, by name, bundle identifier, and the helper tools apps declare.
Anything owned by an app that no longer exists on disk gets grouped under that app and tagged "App removed." Data that belongs to something you still have is never touched, including that app's background helpers.
You see every group, and its size, before anything happens. Cleanup moves items to the Trash. Nothing is ever permanently deleted, so you can put it back.
Safety
MacSweep cross-checks every mounted volume's Applications folders, including bundle IDs and app-declared helper identifiers, so data from an app you still have is never flagged as a leftover.
If it cannot confirm an app is really gone, it leaves the files alone and marks them for your review instead of guessing.
Every removal goes to the Trash. If you change your mind, it is right there.
Scans run locally. MacSweep never uploads your files or file names.

Yes, when the tool confirms the app is actually gone and moves files to the Trash rather than deleting them. MacSweep does both, and protects data from apps you still have.
