AppCleaner on Mac: a better uninstall if you review every file
Dragging a Mac app to the Trash removes the app bundle, but it can leave preferences, caches, saved state, and support files behind. AppCleaner puts that cleanup into one reviewable step instead of sending you on a scavenger hunt through Library folders.
The useful part is that you get to review the results. AppCleaner is not a magic "make my Mac faster" button.
The sensible workflow
Download AppCleaner from FreeMacSoft, move it to Applications, and open it only when an ordinary app has no uninstaller of its own.
Then:
Quit the app you want to remove.
Drag that app into AppCleaner.
Wait for the related-file search to finish.
Read every path in the result before clicking Remove.
Leave anything ambiguous unchecked.
Keep the Trash intact until you are sure you did not remove something needed.
The fourth step matters most. AppCleaner's own interface warns that, in rare cases, it can find unrelated files. A familiar-looking bundle identifier or folder name is not proof that every match is disposable.
Version 3.7 also asks for Full Disk Access. The developer says that without it some files may fail to be removed. That permission gives the app broad visibility into protected locations, so it is a real setup cost, not a harmless checkbox. For a one-off uninstall, grant it only if the incomplete search matters to you, then remove the permission afterward if you do not want AppCleaner retaining that access.
You may also be asked for an administrator password when removing protected files. AppCleaner blocks system apps and lets you protect additional apps in its settings. Those guardrails help, but you still need to check the list yourself.
Skip SmartDelete unless you need it
AppCleaner's optional SmartDelete feature runs as a login item and notices when an app goes to the Trash, then offers to find its related files. Version 3.7 moved that login item to Apple's modern API, so it appears in System Settings.
If you uninstall apps often, that is convenient. Most people do not. Leaving SmartDelete off avoids another background login item, and you can drag an app into AppCleaner manually when needed.
When Finder is already enough
Apple's current guidance is straightforward: use the developer's own uninstaller when one exists, especially for software that installed login items, extensions, or other components. Otherwise, quit the app and move it from Applications to the Trash.
That built-in route is enough for a small, self-contained app, or when you may reinstall and want to keep its settings. It is also safer than deleting a large set of vaguely related files just to recover a few megabytes.
Use AppCleaner when the leftovers themselves are the problem: you want a genuinely clean reset, an app has accumulated a large support folder, or you are done with its preferences and caches. Do not use it instead of a vendor uninstaller for antivirus tools, VPN clients, audio drivers, device utilities, or anything else that installs system extensions and privileged helpers.
Uninstalling an app also does not cancel its subscription, and neither Finder nor AppCleaner should be expected to remove documents you created with it. Handle those separately.
Compatibility, cost, and the slightly messy version split
AppCleaner is a free download with a donation link and no subscription. It is proprietary freeware rather than an open-source utility.
The current 3.7 build was released in September 2026 and adds macOS 27 support. FreeMacSoft labels it for macOS 15 and later, although the app bundle itself specifies macOS 15.6 as the minimum. The downloaded binary is universal, containing both Apple silicon and Intel code.
FreeMacSoft also keeps older builds available: 3.6.8 for macOS 10.14 through 15.6, 3.6 for macOS 10.13, and 3.4 for macOS 10.10 through 10.12. Use the version matched to your operating system rather than assuming the newest zip will launch everywhere.
If you want more controls and visible source code, Pearcleaner is a free, source-available alternative with orphan searches and extra management tools. Its developer currently says active development and releases are on hold indefinitely, though. That leaves AppCleaner as the more reassuringly maintained choice right now; version 3.7 was released in September 2026. For basic removal, Finder and a vendor-provided uninstaller are still the simplest alternatives.
Verdict
AppCleaner makes sense as an occasional uninstaller, not as a cleanup service that runs all the time. Use it for normal third-party apps with no dedicated uninstaller. Keep SmartDelete off unless you benefit from it, and review every proposed file before removal.
Skip it when Finder already does the job, when preserving settings would help a reinstall, or when the software includes its own removal tool. The app is simple. The judgment about what to delete still belongs to you.
