DiskDuo vs CCleaner
CCleaner made its name on Windows. DiskDuo is written for macOS alone: APFS-aware sizes, a real disk map, and a cleanup step that shows every file first.
Compared
CleanMyMac is the best known Mac cleaner there is, and it does a great deal more than clear space. DiskDuo is narrower and cheaper: it measures your disk, shows you every byte, cleans what you approve, and checks the protections macOS already has.
The short answer
If you want one app to look after a Mac and do not mind paying every year, CleanMyMac covers more ground. If you want to see exactly where your space went, decide for yourself what goes, and pay once, that is what DiskDuo is for.
| DiskDuo | CleanMyMac | |
|---|---|---|
| How you pay | One payment, and every 1.x update is included | A subscription, renewed yearly. Checked in September 2026 — verify on their site, since this can change. |
| Disk map | Nine views of one scan, all in step with each other | A space lens with a sunburst view |
| Before anything is removed | Every file listed, with where it came from, then the Trash | A review step, then removal |
| Duplicate finder | Four stages ending byte for byte, APFS clones excluded | Included |
| App uninstaller | Included, with the reason each leftover was matched | Included |
| Malware | Apple's XProtect signatures, run on demand, nothing uploaded | Its own engine, with its own updates |
| Analytics | None. No crash reporting either | Collected, per their privacy policy |
| Where it is sold | Direct, signed and notarized by Apple | Direct and on setapp |
This is the honest difference. CleanMyMac is a subscription: you keep paying to keep using it. DiskDuo is bought once and stays yours, with every 1.x update included, on one Mac at a time that you can move to a new machine. If you only need to find and clear space a few times a year, a yearly bill is a lot for the job.
DiskDuo opens on a measurement, not a recommendation: a treemap of your own disk, with nine ways to read it and a selection that follows you between them. It will suggest easy wins, but the map comes first. That ordering is deliberate — you should be able to answer “what is taking the space” before anyone offers to delete something.
DiskDuo has no analytics and no crash reporting. It contacts its server to activate a licence and to look for updates, and for nothing else. Its malware scan reads the XProtect signatures macOS already keeps, so even that stays local. Compare that with any cleaner’s privacy policy before you install it, including this one’s.
It does not speed up your Mac, flush RAM, kill processes on a schedule or promise tune-ups. There is no maintenance script it runs for you. It measures, it shows, it removes what you approve, and it tells you the state of the protections macOS already has.
CleanMyMac is the more complete suite: maintenance scripts, a menu bar assistant, malware monitoring of its own, and years of polish behind it. If you want one app to look after everything and you are happy with a subscription, it is a reasonable buy.
Questions
For finding and clearing disk space, yes, and for a one-time price. For system maintenance beyond that, it is deliberately narrower.
Yes. They do not interfere with each other; both move files to the Trash rather than deleting outright.
