CleanMyMac (MacPaw) is the most marketed Mac cleaner on earth, and to be fair to it: the UI is good, the safety rails work, and if you want one button, it delivers. But "fine" is not "necessary". Depending on which job you actually have, there is a cheaper — often free — path.
| Tool | Price | Best at | Weak at |
|---|---|---|---|
| CleanMyMac | Subscription | One-button sweeps, maintenance scripts | Price; you pay for convenience |
| DaisyDisk | $9.99 once | Seeing the whole disk at a glance | Does not delete caches for you |
| OmniDiskSweeper | Free | Fast size listing, zero ceremony | Ugly, no safety rails |
| GrandPerspective | Free | Treemap visualization, open source | Dated UI |
| Terminal (our guides) | Free | Exact, surgical cache cleanup | Requires following instructions |
| MacCleaner PRO | One-time tiers | Scheduled sweeps across cache families | Less polished UI |
Do you know what is eating the disk? If no — start visual (DaisyDisk or the free treemaps). If yes and it is a named cache family — start with our free guides (Docker, Claude Code, Telegram, Xcode are the usual suspects; the estimator ranks yours). Only if you want recurring automation without scripts does a paid suite earn its price.
We link affiliate tools on this site, and we use several of them. But the ordering above is what we actually recommend to friends: free diagnosis first, targeted free fixes second, paid automation last. A Mac that gets a monthly 30-minute pass with free tools stays cleaner than one running a paid suite nobody configured.
The background knowledge that makes any of these tools unnecessary most of the time: System Data explained, Purgeable space decoded, and the cleanup hub index.
