How to undo a removal.

By Grant and Brad, who make Pangalin's apps · Updated 10 October 2026

Everything Pangalin Uninstaller removes goes to your Trash, so it can come back until you empty the Trash. For your latest removal there's a one-click Undo; for anything older, use Finder.

Undo your latest removal

1. Look at the status line at the bottom of the window, which describes what was just moved.
2. Click Undo. Everything from that removal goes back to where it was, and the app list refreshes.

Undo covers the most recent uninstall, reset or leftover removal, including an app's emptied folder in Applications. If it included items macOS owns, macOS asks for your approval (password or Touch ID), unless you approved in the last 5 minutes. It's available until any of these happens:

• you remove something else
• you close the status line with ✕
• you quit the app

Bring back anything older

Finder's Put Back isn't offered for files an app moves to the Trash, so you move them back yourself. The activity log tells you where each one came from.

1. In Finder choose Go › Go to Folder… (⇧⌘G), open ~/Library/Application Support/Pangalin Uninstaller and open actions.log. Each line that begins COMMIT-ITEM shows an item's original location.
2. Open the Trash from the Dock. Sorting by Date Added (View › Sort By › Date Added) puts the most recent removals together.
3. Drag each item back to the folder the log shows. For a folder inside your Library, open a second Finder window with Go › Go to Folder… and drag the item into it.

To bring back a whole app, move back the app itself (to Applications) as well as its support files, so its settings come back with it.

What can't be undone

• Anything emptied from the Trash. Emptying the Trash is permanent. Only a backup, such as Time Machine, can bring it back. If some items were already emptied, Undo tells you how many it couldn't restore.
• Changes in the Startup tab happen straight away and aren't covered by Undo. A launch agent you switched off can be switched back on in the same place. One you removed is in the Trash, so you can drag it back to ~/Library/LaunchAgents. System items removed there are kept in /Library/Application Support/Pangalin Uninstaller/Removed Startup Items, not in the Trash.
• Apps removed with Homebrew. Uninstall with Homebrew deletes the app instead of moving it to the Trash, so Undo brings back only the leftovers that went to the Trash. To get the app back, reinstall it with brew install --cask <name>.
• Apps deleted from the Trash. Delete from Trash… deletes an app permanently, and starting it ends Undo for your last removal.
• Privacy permissions. A reset can't be undone. The app asks for each permission again if you install it later.
• Items changed in the Trash: if a system-owned item was changed while it was in the Trash, Undo leaves it there rather than putting it back with administrator rights, and says so.
• If something new is in the way: when a file already exists at the original location (for example you reinstalled the app), Undo leaves that item in the Trash and says so.
