Dragging an app to the Trash on a Mac feels like a clean uninstall, but it rarely is. Preference files, caches, and support data usually stick around in the background long after the app itself is gone. I use App Cleaner & Uninstaller Pro for a full uninstall workflow, but if you’ve already deleted apps the manual way over the years, you need something that can hunt down the leftovers retroactively.
Ghost Buster Pro 6.0.0 is built specifically for that cleanup job. It’s developed by Sascha Simon, and it’s a lightweight macOS utility that scans your system for files left behind by apps you’ve already uninstalled, then lets you review and delete them with a single click. I keep it alongside CCleaner for general system maintenance, though Ghost Buster Pro focuses narrowly on this one specific problem rather than trying to be a full system cleaner.
The workflow is deliberately simple. Open the app and it immediately starts scanning for leftover files from apps no longer on your system. Nothing gets deleted automatically, you review the results and choose what actually gets removed, which matters if you’re not 100% sure whether a file belongs to something you still use. A blacklist feature lets you mark specific items to skip permanently, so repeated scans don’t keep flagging the same files you’ve decided to keep.
A recent update reworked the interface with a clearer summary of how much space you stand to reclaim, a chart showing which leftover files are taking up the most room, and size indicators next to each item in the results list. That makes it easier to prioritize cleanup around the files actually worth removing, rather than manually clicking through a long undifferentiated list.

Why I Recommend
The no-automatic-deletion approach is what makes this safe to run without much risk. A lot of cleanup utilities are a little too aggressive about what counts as “junk,” and getting that wrong can break an app you still actually use. Ghost Buster Pro puts the decision in your hands every time.
The blacklist feature is a small but practical addition. Once you’ve reviewed a file and decided to keep it, not having it flagged again on every future scan saves real time if you run cleanup scans regularly.
If you’re maintaining a Mac long-term, it’s worth browsing our Mac Software section for other cleanup and uninstall tools that pair well with a leftover-file scanner like this one.
