The average Mac has 8–15 GB of completely safe-to-delete junk hiding in caches, logs, and app leftovers. CleanMachine finds it all in 60 seconds — free — and removes it safely so you stop seeing that "startup disk is almost full" warning.
Every app on your Mac stores temporary files to run faster. Over time these caches balloon to gigabytes — and most of them are from apps you barely use. macOS never deletes them automatically. CleanMachine finds them across all apps and clears them safely — apps just rebuild what they need next time they run.
That giant "System Data" chunk in Mac storage settings isn't really system files — it's a catch-all for logs, caches, temp files, and old app support data. CleanMachine breaks it down into plain categories (system logs: 2.1 GB, mail attachments: 800 MB, app support leftovers: 1.4 GB) so you know exactly what you're removing.
When you drag an app to the Trash, it leaves support files, preference files, and cached data scattered in Library folders. These orphaned files take up space forever — the app is gone but its junk remains. CleanMachine's App Uninstaller finds every leftover associated with deleted apps.
Safari, Chrome, Firefox — each builds a local cache of every webpage you've visited. These caches can reach several GB on their own and have zero value once the page visit is over. CleanMachine clears all browser caches in one shot without touching your bookmarks or saved passwords.
The Large File Finder shows you the biggest files on your Mac sorted by size — installers, old video exports, archive files you extracted and forgot about. Usually the quickest way to recover 5+ GB instantly.
Scans your Mac in 60 seconds. Shows exact sizes per category — system caches, user caches, logs, browser data, app support. Remove all or select what you want.
Interactive map of your entire storage — every folder, every file, sorted by size. Instantly see what's taking the most space so you can decide what to keep.
Surfaces files over 50 MB sorted by size. Old installers, forgotten exports, archive files — find them all in one list and delete what you don't need.
Remove apps AND all their leftover files at once. Gets every support file, cache, and preference file that a normal app deletion leaves behind.
Finds exact duplicates taking up double the space — same file, two copies. Common after years of file reorganization, backups, and iCloud downloads.
Set it and forget it — CleanMachine cleans your Mac weekly or monthly so storage never creeps back up. You never have to remember to do it manually.

The average Mac has 8–15 GB of junk files that are completely safe to remove — app caches, system logs, browser data, leftover files from deleted apps, old downloads. CleanMachine finds all of it in a free 60-second scan and shows you exactly what's there before you remove anything.
"System Data" in macOS Storage settings is a catch-all for caches, logs, temp files, and app support data. Most of it is safe to remove. CleanMachine breaks down what's actually in there — cache files, app logs, language files — and lets you remove what's safe without touching what macOS actually needs.
Yes — when your storage is above 80% full, macOS starts swapping memory to disk. This makes your Mac feel sluggish, especially on SSDs with limited space. Freeing 8–15 GB typically resolves memory pressure, speeds up boot times, and stops the spinning beachball.
CleanMachine only removes junk — caches, temp files, app leftovers, browser data. Your documents, photos, and anything you created are never touched. Everything also goes to a recoverable CleanMachine Trash before permanent deletion, so you can restore anything in a mistake.
Yes — CleanMachine's scan is always free. Download it, click Scan, and in 60 seconds you'll see a complete breakdown of exactly what's using your storage. Cleaning costs $19.99 once — but you can see the full picture for free first.
