Find Out What's Really
Eating Your Disk Space
macOS tells you the disk is full, not what's on it. OverClean scans every folder, sorts what it finds, and shows you the files, apps, and leftovers actually using the space.
Sound familiar?
"Your startup disk is almost full."
Storage settings shows a big grey "System Data" slice — and no way in.
You deleted an app months ago. Its files are still there.
You don't know which of your apps is the heavy one.
You're not sure what's safe to remove, so you remove nothing.
Problem
macOS won't tell you what's using the space
OverClean scans your entire disk with real-time progress, then sorts everything it finds into 26 categories on an interactive dashboard — so instead of one grey slice, you see exactly where the space went.
See the dashboard Problem
Apps you uninstalled left their files behind
Leftovers Detection scans Application Support, Caches, Preferences, and Logs for data with no app left to own it — orphaned files that sit there indefinitely unless something goes looking for them.

You can't tell which app is actually heavy
The Applications Manager lists every installed app with its real bundle size, sortable and searchable, so the biggest offenders surface immediately instead of staying hidden in Finder.

You're afraid to delete the wrong thing
OverClean analyzes and reports — it never deletes anything on its own. Every removal is a manual, confirmed action that goes through macOS Trash, and protected system paths stay off-limits.

For developers
Write code on this Mac? There's more hiding.
Xcode DerivedData, archives, and tool caches. iOS Simulators and their test clones.
node_modules, Python virtual environments, Docker images,
Git objects — all of it lives outside Finder's view. OverClean finds each of these as
its own category, with sizes down to the individual item.
