Yes, CleanMyMac is a real Mac utility made by MacPaw, a company founded in 2008 with headquarters in Kyiv, Ukraine, and its product page shows a Notarized by Apple badge. It needs Full Disk Access to scan everything, so it's worth understanding that permission and downloading only from MacPaw's own site or an official store.
A cleaner that asks to look through your whole Mac is a fair thing to be nervous about, and I'm glad people ask "is CleanMyMac safe" before clicking install. I've read MacPaw's about page, its Full Disk Access article, its refund policy and the Wikipedia history, so here's what the company itself says and where I'd be careful. I'm sharing what its pages state, not running a security audit.
Who makes CleanMyMac
It comes from MacPaw. MacPaw's About page says the company was founded in 2008, bootstrapped with CleanMyMac, which was developed by then-student Oleksandr Kosovan, who later became CEO. Its headquarters is in Kyiv, Ukraine, with offices in Kyiv and Boston.
According to Wikipedia, CleanMyMac is a macOS maintenance utility and MacPaw's first commercial product. MacPaw also makes Setapp, Gemini, ClearVPN and The Unarchiver. So this isn't a one-app startup that might vanish, but a company with a long product history and a named founder.
What CleanMyMac does on your Mac
Its product page lists cleaning junk files, finding duplicate and similar photos, scanning for and removing malware, fully uninstalling apps and updating software. The page gives system requirements of macOS 11 or later and 320 MB of storage.
A fair warning: those are the vendor's own claims. The page doesn't cite an independent test of its malware scanning, so I wouldn't treat it as a replacement for the security you already have. Think of it as housekeeping with an extra scan on top.
Notarization, Full Disk Access and what you're allowing
The product page shows a Notarized by Apple badge. Apple's notarization is a check Apple runs on software distributed outside the App Store, and it means the app has been scanned for malicious content. It doesn't mean Apple endorses what the app does, so you still need to understand the permissions you give it.
The big one is Full Disk Access. MacPaw's article calls it a security permission that utilities like CleanMyMac require to perform essential tasks. macOS normally blocks apps from protected areas such as Mail, Messages and Safari data, and MacPaw says that without the permission CleanMyMac can't scan all areas of your Mac for junk files or malware.
That is a lot of access, so what does MacPaw promise in return? Its article says CleanMyMac only operates when you explicitly initiate it, and that it doesn't transfer any personal data beyond your Mac, including work documents, chat histories or emails. It adds that it collects only analytics data to improve the app, handled under GDPR and MacPaw's Privacy Policy.
To grant the permission on macOS Ventura or later, go to System Settings, then Privacy & Security, then Full Disk Access, and turn on CleanMyMac, confirming with Touch ID or your password. If you ever change your mind, you can switch it off in the same place.

What to watch for with CleanMyMac
First, cleaning tools can do harm if you delete things blindly. Look at what CleanMyMac proposes before you confirm, and keep a backup of anything you care about, such as your photo library. Large files and old downloads are the usual targets, so make sure you recognise them.
Second, the company has had some noise outside its software. According to Wikipedia, in 2023 Ukrainian authorities searched MacPaw's Kyiv office and the CEO's home over a land dispute, which MacPaw denied, and the Supreme Court closed the related proceedings that year, leaving MacPaw as holder and user of the disputed property. That's a business matter, not a product safety finding, but you may want to know about it.
Third, your Mac may not need a cleaner at all. If you want other tools that touch your accounts and passwords, my guide to weighing up password managers shows the sort of questions I'd ask of any app that holds sensitive access.

CleanMyMac refunds and subscriptions
MacPaw's refund policy for purchases from its own store says you can ask within 14 days of the initial purchase for monthly or shorter billing intervals, and within 30 days for all other purchases. Only the initial subscription purchase is refundable, not automatic renewal payments. You contact Customer Support by email or phone, and refunds should appear on your card statement within 7 to 10 business days.
Where you bought matters. MacPaw says purchases processed through Apple's App Store are governed by Apple's refund policy and MacPaw can't refund them, and purchases from third-party resellers such as Amazon must go through the reseller. MacPaw's support site also has a subscription manager, so you can see what's renewing.
Fake CleanMyMac downloads and support scams
Popular Mac cleaners attract fake download pages and pop-ups claiming your Mac is infected. Here's how I'd stay safe:
- Download CleanMyMac only from macpaw.com or the official Mac App Store, typing the address yourself.
- Ignore browser pop-ups that say your Mac has a virus and push you to install a cleaner.
- Don't call phone numbers shown on a warning screen; use the support pages on MacPaw's own site.
- Never install a cracked or free copy from a file-sharing site; that's a common way to catch malware.
- If you think a file is malicious, MacPaw's support site has a Submit Malware page.
The same caution applies to any tool with deep access, and my tips on stopping hackers touching your website cover the habits that keep accounts safe across devices.
My verdict on CleanMyMac
It's real software from an established company, with a notarized badge, a stated privacy position and a clear refund policy. It isn't a scam. But it asks for deep access to your Mac, so download it only from official sources, read what it wants to delete and decide whether you need it at all.
