Merely removing apps on Mac OS X is not a hard thing to do: drag & drop or just delete to the Trash. But sometimes after such removal on your Mac, there could be left system files, caches, logs, and other debris – called app leftovers. That is why it is better to use special third-party app uninstallers for removing programs from your Mac with all their service files.
