Is CleanMyMac safe to use?

Is CleanMyMac malware or a scam?

No. CleanMyMac is made by MacPaw, which has sold it for many years. MacPaw renamed CleanMyMac X to the new CleanMyMac in October 2024, and its Safety Database, the list of what it should and shouldn't remove, dates back to 2008. You can get it three ways: the MacPaw Store, the Mac App Store and Setapp, which MacPaw also owns.

MacPaw says the app is notarized. That means Apple's automated notary service checked it. Apple describes notarization as a scan for malicious content and code-signing problems, and says plainly that "notarization of macOS software is not App Review". The Mac App Store version went through App Review as well. So CleanMyMac is not malware and not a fake. Whether it's safe for your files is a different question, and it depends on which tools you use and how.

Does Apple approve or recommend CleanMyMac?

Apple checks that the app is what it says it is. It doesn't vouch for what the app removes. We found no Apple support page that recommends CleanMyMac or any other third-party cleaner.

What Apple documents instead is the Mac's own Storage settings:

Apple menu, then System Settings, then General, then Storage

There you'll find recommendations such as Store in iCloud, Optimize Storage and Empty Trash automatically. Apple's Optimize storage space page also says that when space is needed, macOS clears caches and logs that are safe to delete, such as temporary database files, interrupted downloads, staged macOS and app updates, and Safari website data. Apple's Free up storage space on Mac article covers the rest: moving files to an external drive, removing media you can download again, uninstalling apps, deleting old iPhone backups and emptying the Trash.

That matters when you weigh any cleaner. Much of what a "system junk" scan finds is the same kind of cache macOS already clears when it runs short of space, and apps rebuild it as you use them.

What CleanMyMac does well

Be fair to it: CleanMyMac is a broad, polished suite, and some people want exactly that.

• Breadth. Alongside cleanup it has malware scanning, an uninstaller and app updater, duplicate and similar-photo finders, a bubble map of your disk called Space Lens, menu bar monitors and cleanup for iCloud, Google Drive, Dropbox and OneDrive. See the product page.
• Guard rails. It uses MacPaw's Safety Database and lets you add folders to ignore lists for Cleanup, Protection, Applications and My Clutter.
• Careful defaults in places. Nothing in its duplicate finder is selected for you (MacPaw), and Xcode module caches and archives aren't auto-selected in System Junk (cleanup list).
• Easy to try and easy to get. A free 7-day trial on all three stores (editions) and a 30-day money-back guarantee on the MacPaw Store. It runs on macOS 11 Big Sur and later.

What to watch for

These points come from MacPaw's own help pages and store, checked October 22, 2026.

• Some tools delete permanently. The help pages for Large & Old Files and Duplicates say removed files skip the Trash. Items from the Photos library go to Recently Deleted instead. For System Junk, Space Lens and the uninstaller, the help pages don't say where removed items go.
• Review is optional. For System Junk you can open Review All Junk, or click Clean on the tile and remove everything it found without looking (System Junk). Smart Care runs several routines in one click.
• No undo is documented. None of the safety, Space Lens, Large & Old, Duplicates or Uninstaller articles describe a way to restore what was removed.
• Caches come back. System Junk includes user and system cache files (cleanup list). Removing them frees space until the apps rebuild them, which for browsers and busy apps is usually days.
• Subscription first. Prices checked October 2026, for one Mac: Essential Trio $19.95 a year, All-in-One $39.95 a year or $9.95 a month, or $119.95 one-time (MacPaw Store). The one-time license doesn't expire but covers updates only within the current major version (purchase options).
• An account and some data collection. MacPaw Store licenses are activated by signing in to a MacPaw Account (activation); App Store and Setapp copies don't need one. The privacy policy lists usage analytics through Google, error reports through Sentry, and log data it describes as mandatory, including cleanup activity logs with file paths.

None of this makes CleanMyMac dangerous. It means the app trusts you to read the list, and some of its removals have no way back except your own backup.

How to use CleanMyMac more carefully

If you keep using it, a few habits cover most of the risk:

1. Have a current backup first. Apple's Time Machine guide walks through it. For Duplicates and Large & Old Files, a backup is the only way back.
2. Open the list instead of clicking Clean. Use Review All Junk and look at what's selected before anything goes.
3. Treat Duplicates and Large & Old Files as permanent. Check each file, and check which copy is being kept.
4. Add folders you care about to the ignore lists, such as project folders or a second Photos library.
5. Skip caches unless you need space today. macOS clears them itself when space runs low, and apps rebuild them.

What's safe for any cleaner to remove, and what isn't

The same rules apply whichever app you use.

Usually safe, and stays gone for a while: old app logs and crash reports, Xcode DerivedData, package manager caches such as npm, pip and Homebrew downloads, and installers you've already used.

Safe, but comes back: app and browser caches. You lose nothing, but the space returns as you use the apps. Our guide to clearing caches on a Mac covers which ones are worth it.

Check yourself first: large old files, Downloads, duplicate files (especially inside Photos or project folders) and anything in Application Support for an app you still use.

Leave alone unless you're sure: iPhone and iPad backups, which can't be made again later, Mail and Messages data, and anything inside iCloud Drive, where removing a file removes it from every device.

Is CleanMyMac worth it?

It depends on the job. If you want one app that also scans for malware, updates apps, watches CPU and battery and cleans cloud storage, CleanMyMac covers all of that, and a trial will tell you whether you like it.

If disk space is the only problem, you may not need a suite. Start with Storage settings, then pick a tool for the specific job: a free disk map to find what's big, a free uninstaller, or a one-time app that reviews everything first. Our best Mac cleaner guide compares the free and paid options, and CleanMyMac alternatives lists apps without a subscription. If an app is the problem, see how to uninstall apps completely.

How MacClearings handles the same job

We make MacClearings, so read this part with that in mind. It does disk space only. It has no malware scanner, no cloud cleanup and no system monitor beyond each running app's CPU and memory.

What it does differently is how files leave. Every item, from every view, goes through one review list and then to the Trash. Right before it moves, each item is checked again: if it's gone, changed since it was measured, open in an app or now protected, it's skipped and you're told why. History records where everything went, with Undo for a whole cleanup and Put Back for a single item. MacClearings never empties the Trash, so the space comes back when you empty it yourself, and until then anything can go back.

It also doesn't check app or browser caches for you, because they come back within days. It costs $25 once, needs no account and has no analytics. The side-by-side comparison has the details, and the safety page explains every rule.
