I should be upfront: I make a much smaller, cheaper Mac app called Shiny. So you should treat my opinion on CleanMyMac with appropriate scepticism. I've tried to write this honestly. Where CleanMyMac is the right tool for someone, I'll say so.
Is CleanMyMac safe?
Yes, in every way that matters.
- Apple has approved it. CleanMyMac is signed with a valid Apple Developer ID and notarized by Apple, which means Apple has scanned it for malware before you ever download it. Same standard every legitimate Mac app has to clear.
- It's not malware. It doesn't track you for advertisers, doesn't send your files anywhere, doesn't install hidden background processes. MacPaw's privacy policy is clear about what it collects (anonymous usage stats by default, which you can disable).
- The company is real. MacPaw has been on the App Store side of the Mac ecosystem since 2008. They make Setapp, CleanMyMac, ClearVPN, and Encrypto. They have offices, employees, and a public reputation to protect.
People often confuse CleanMyMac with MacKeeper, which is a totally different app made by a totally different company (Clario, formerly Kromtech and before that Zeobit). MacKeeper has a much rougher history. CleanMyMac is fine. MacKeeper, less so. We covered MacKeeper in a separate post if you want the long version.
So why are people asking if it's safe?
Three reasons, none of them really CleanMyMac's fault:
1. The category has a bad reputation. "Mac cleaner" apps were dominated for a decade by tools that were straightforward scareware: aggressive popups, fake virus warnings, "your Mac is at risk" alerts designed to scare non-technical users into buying. CleanMyMac is part of that category by name even though it doesn't behave that way.
2. Confusion with MacKeeper. The names are almost interchangeable in casual conversation, and MacKeeper genuinely earned a scareware reputation. People assume CleanMyMac is the same. It isn't.
3. CleanMyMac itself is a bit pushy. It pops up "Smart Care" reminders to scan, sends notifications about fragmented disks (a thing modern macOS doesn't actually have), and has marketing that sometimes overpromises ("speed up your Mac up to 10x"). None of this is dangerous, but it makes the app feel salesier than it needs to be.
Do you actually need it?
This is the question worth asking. The honest answer for most people is "probably not, but it depends what you're trying to do".
CleanMyMac bundles together about a dozen small jobs. If you do all of them regularly, the bundle is worth it. If you only need one or two, you can usually find a cheaper, more focused alternative. Here are CleanMyMac's main jobs and what most people end up actually using:
System junk & cache cleanup. macOS already cleans up after itself most of the time. Caches refill on use; cleaning them daily isn't doing anything. This is mostly cosmetic.
Memory cleaning. Useful when memory pressure goes red (see what memory pressure means). One-click frees up RAM. Smaller apps like Shiny ($4.99 once), Memory Cleaner (free with paid upgrades), or just running sudo purge in Terminal do the same job.
Malware scanner. Genuinely useful, but macOS already has a built-in malware scanner called XProtect that runs silently. CleanMyMac's scanner adds a second layer, which is fine but not essential. If you only want malware protection, Apple's free XProtect documentation explains what's already there.
Uninstaller. Cleanly removes apps and their leftover files. AppCleaner does this for free, and is widely considered the best of its kind.
Large & old files finder. Helps you find what's eating your disk. macOS already has this built in: Apple menu › About This Mac › More Info › Storage Settings. Or for a more visual version, DaisyDisk ($9.99 once).
Maintenance scripts. Things like clearing old logs, repairing permissions, rebuilding Spotlight. Apple's free tool OnyX does these and is highly regarded.
When CleanMyMac actually is the right choice
I'll be honest: for some users, CleanMyMac is the right tool.
You should consider it if:
- You want one app to do everything Mac-maintenance-related and don't want to think about it.
- You like having a malware scanner with a friendly interface that flags things visually.
- You'll genuinely use 4 or more of its features regularly (not just open it once a year).
- You don't mind the subscription model and find $40/year reasonable for the breadth.
You probably don't need it if:
- You only want one of its jobs (memory clearing, app uninstalling, disk visualisation).
- You prefer pay-once tools to subscriptions.
- You're already comfortable with built-in macOS tools (Activity Monitor, Storage Settings).
- You find the popups and Smart Care reminders annoying. They're not subtle.
The smaller-tool alternative
If you only want some of CleanMyMac's jobs, here's a kit of single-purpose tools that costs less than one year of CleanMyMac and gives you more control:
- Memory clearing: Shiny ($4.99 once) or Memory Cleaner (free).
- Uninstalling apps: AppCleaner (free).
- Disk visualisation: DaisyDisk ($9.99 once) or built-in Storage Settings.
- Malware: macOS XProtect (built in) and Malwarebytes free scanner if you want a second opinion.
- Maintenance scripts: OnyX (free).
Total cost: about $15 once. Versus $40/year for CleanMyMac. The trade-off is that you have to know which tool to open for which job, and you don't get the unified dashboard.
Bottom line
CleanMyMac is safe. It's a real product made by a real company. It does what it says.
Whether you need it depends on how much of its breadth you'll actually use. If you'll use most of it, it's a fair deal. If you only need one of its jobs, a smaller tool will probably serve you better at a fraction of the cost.
And as the maker of one of those smaller tools, I'm of course biased. I'd still tell anyone whose Mac genuinely has malware concerns or wants the all-in-one experience that CleanMyMac is a reasonable choice. It's just not the only one.
