Drag an app into AppZapper 3000 and it lists everything that app scattered through ~/Library — caches, preferences, support files — then hands you an exquisitely detailed 3D laser gun to shoot them with, explosions and smoke included. Zapped files go to the Trash and Undo works, so the theatrics cost nothing. It’s Austin Sarner and Brian Ball’s 2006 original, rebuilt: $18 once, macOS 15 or later, three free zaps to try.
