The platform-origin question
CCleaner was built for Windows first, where it became one of the most widely used cleanup utilities of the 2000s and 2010s. The Mac version arrived later and is generally regarded, including by Macworld's own comparison coverage, as thinner than both the Windows original and Mac-native competitors like CleanMyMac. It covers the basics (junk file scanning, some privacy cleaning, a simple uninstaller) without the depth of Mac-specific features CleanMyMac has built up over a much longer dedicated development history.
There's also a brand-history factor worth naming plainly. CCleaner suffered a serious supply-chain security incident in 2017 on the Windows side, where a compromised build briefly distributed malware to millions of users before being caught and patched. The Mac version wasn't directly affected, but the incident happened under the same corporate ownership and is part of the honest history worth knowing. The company (now Gen Digital, formerly Piriform, then Avast) has a legitimate, large security business, but that 2017 incident is a real data point for anyone weighing trust in the brand.
Where CleanMyMac wins
Depth. Built exclusively for macOS since 2010, CleanMyMac's features are noticeably deeper and more Mac-specific: smarter cache identification, a proper memory optimiser, and malware scanning tuned to Mac threats specifically.
Focus. MacPaw is a Mac-only software company. Its entire roadmap is built around this one platform, rather than a Mac version of a Windows-first product.
Where CCleaner wins
A genuine free tier. CCleaner's free version does real cleanup work at no cost, which CleanMyMac doesn't offer (it's subscription or lifetime purchase only, no ongoing free tier).
Lower Professional pricing. At $29.95-49.95 a year for the paid tier, CCleaner Professional undercuts CleanMyMac's $39.95-89.95 range, if you're comparing paid-to-paid.
Brand familiarity. If you've used CCleaner on Windows for years, the Mac version offers a familiar interface, even if the feature depth doesn't fully match.
Which one should you use?
If you want the deepest Mac-specific cleanup and don't mind paying for it, CleanMyMac's longer, platform-dedicated history shows in the feature depth. If you want to try something free first, or you already trust CCleaner from Windows use, its free tier is a legitimate starting point, understanding you're getting a thinner feature set than a Mac-native tool.

What "thinner on Mac" looks like in practice
It's worth being specific about where CCleaner's Mac feature gap actually shows up, rather than leaving it as a vague impression. The Windows version includes registry cleaning, a much larger library of browser and application-specific cleanup rules built up over two decades, and deeper system-level tweaking options. macOS has no registry to clean, so that specific feature simply doesn't translate, but the broader pattern holds: CCleaner's Mac development has historically received less attention than CleanMyMac's, which has been Mac-only since day one. That doesn't make the Mac version useless, its core junk-cleanup and privacy features work as advertised, but if you're expecting Windows-level depth, the honest expectation should be calibrated lower.
Checking the 2017 incident's relevance for Mac users
It's worth being precise about scope here, since the 2017 incident is often mentioned vaguely. A compromised build of the Windows CCleaner application briefly distributed a piece of malware to millions of users before Piriform (the company at the time) caught and patched it. This was a build-server compromise specific to the Windows release pipeline; there is no equivalent documented incident tied to the Mac build. The relevance to Mac users is really about company-level trust rather than a direct technical risk to the Mac app itself, and it's reasonable to weigh that distinction when deciding how much the incident should factor into your decision.
A smaller, unrelated option worth knowing
We make Shiny, a $4.99 menu-bar app that frees memory, disclosed for transparency. If the only feature you'd use from either suite is memory cleanup specifically, that's a narrower, cheaper, one-time purchase; Shiny vs CleanMyMac covers that comparison directly.
What actually matters for most buyers
Strip away the brand history for a moment and the practical question is simpler than it first appears: how many of CleanMyMac's or CCleaner's individual features would you genuinely use in a typical month? If the honest answer is "just junk cleanup, maybe once every few weeks," CCleaner's free tier likely covers that need entirely, and paying for CleanMyMac's deeper feature set would mostly go unused. If you're someone who wants malware scanning, a proper memory tool, and thorough disk cleanup all handled by one dependable app you don't have to think about, CleanMyMac's higher price buys genuinely more capability for that broader use case.
