What dragging to the Trash leaves behind
~/Library/Application Support/AppName, often the biggest part- Caches, preferences (
.plist), saved state and logs - Containers and group containers for sandboxed apps
- Launch agents and login items that keep trying to start
Uninstall with Broom
- Open ApplicationsEvery app with its full footprint, not just the size of the .app.
- Pick an appSee its support files, caches and preferences listed with sizes.
- UninstallThe app and its files move to the Trash together.
Leftovers from apps you already deleted
Broom also lists data from apps that are no longer installed, and Add-ons lists launch agents and login items whose app is gone first. These are usually safe to remove and easy to forget.
Questions
Does dragging an app to the Trash uninstall it?
It removes the app bundle. Its support files, caches and preferences in your Library folder stay behind.
Can I undo an uninstall?
Yes. Everything goes to the Trash, and Activity has a Put back button for each uninstall.
