The most boring job on a Mac, deleting an app’s leftovers, done with a glossy 3D ray gun, and done properly.
Drag an app into the window and AppZapper 3000 lays out everything that came with it: the .app itself, its caches, preferences, support folders and receipts. Uninstall iMovie in the maker’s demo and that is nine items and 4.35 GB. Then a green-and-red ray gun rises into the bottom corner of the window, follows your mouse, and each click fires a laser bolt that blows the icon it hits into green smoke. The gun has recoil. It comes in the classic livery or one of several new blaster themes. If you would rather not aim, Zap All clears the lot.
That kind of excess is the point. Austin Sarner and Brian Ball first shipped AppZapper in 2006, when Mac indies competed on delight: Paul Kafasis called them “the Delicious Generation”, and Disco, a disc burner from the same circle, puffed smoke you could blow away through the microphone. The App Store and iOS 7’s flat design ended that era. This rebuild, credited to Sarner, Ball and Clemens Knieper, brings it back. Inside the app are a SceneKit scene for the gun and separate video clips for sparks, energy blasts and smoke, with sounds to match.
The theatrics are safe. John Gruber, who tested it for weeks before the relaunch, reports that zapped files go to the Trash and that AppZapper supports Undo if you get trigger-happy. The maker’s page doesn’t mention either, so that is his account, not a promise from the developers.
Gruber also makes the honest case against the whole category: macOS doesn’t need uninstallers, and leftover preferences cost nothing. The real reason to use one is the large files a trial app stashes in ~/Library, and there are far more trial apps now than a few years ago.
It costs $18 for one Mac, $29 for up to five and $99 for 25, sold directly with no App Store listing, and the trial is three free zaps. The site says macOS 15 or later, but version 1.0’s own bundle asks for 15.6. It is signed with Sarner’s Developer ID, updates itself through Sparkle, and includes the TelemetryDeck analytics SDK.
