AppCleaner – Completely-free Mac app uninstaller Free App Uninstaller for Mac – AppCleanerįreeMacSoft developed one popular free app remover for Mac users – AppCleaner. And by following some criteria, we finally picked out these top app uninstallers for you. We’ve reviewed more than 10 programs people use to remove apps on Mac computers. That’s why you need some advanced app uninstaller software to help you completely delete them. The worse is that you suddenly find the app is some malicious program that you cannot remove from your Mac computer. But the regular app removal on macOS does not entirely remove everything about the app – It just deleted the app but didn’t remove app preferences data, app caches, downloading files, and use history. Sometimes we may realize that we do not need some app anymore.
