Do you need a cleaner app at all?
For basic cleanup — no: the Trash, Downloads, large files, apps and cache can be cleaned with macOS itself — how to clean up your Mac.
An app helps when System Data takes the most space and has no Clean button, when you need to sort through ~/Library without deleting app data along with cache, or when Xcode, Homebrew and npm files pile up.

WIWIClean
Our app, so we describe it as dryly as the rest. Storage shows the disk by category: Applications, App Data, Developer, Documents, System caches, macOS & other. Recommendations: Caches & logs with one button, Unused (apps and files not opened for 6+ months) and macOS update. App Data shows each app's cache and data separately.
- Safety: a “?” on every row explains what happens after deletion; macOS files can't be deleted.
- Price: analysis is free forever, all features free for 7 days without a card, 30-day refund.
- Cons: no malware scan, no one-click uninstall with leftovers, macOS 26+ and Apple Silicon only.
CleanMyMac
The best-known all-in-one cleaner from MacPaw: junk cleanup, malware removal, app uninstaller and updater, duplicates and similar photos.
- Price: $29.95/yr for one Mac, 7-day trial.
- macOS: 11 and later, 12 interface languages.
- Cons: the most expensive yearly plan in this review.

OnyX
A free maintenance utility from Titanium Software: checks system files, runs cleanup and maintenance tasks. Each macOS version has its own OnyX version. It's a set of technical tools rather than a list of what to delete — not easy for beginners.
DaisyDisk
A visual disk analyzer: $9.99 once, license for 5 personal Macs. Works on Intel too. The trial is unlimited but can't delete files — you decide what's safe to remove yourself.
GrandPerspective
A free open-source analyzer that shows the disk as a map of rectangles — the biggest files stand out at once. $2.99 in the Mac App Store for the same app.
OmniDiskSweeper
A free list of files from largest to smallest with a Trash button. It doesn't tell you what's safe to delete — be careful in ~/Library and system folders.
AppCleaner
Does one thing: drag an app into its window, and it finds and removes the app's related files. Free, donations via PayPal. More — how to uninstall apps completely.
FAQ
Are there free Mac cleaner apps?
Yes: OnyX, OmniDiskSweeper, AppCleaner and GrandPerspective (SourceForge). WIWIClean's analysis is free forever. DaisyDisk's trial is unlimited but can't delete.
Are Mac cleaners safe?
An app from the developer's website or the App Store isn't dangerous by itself. The main risk is deleting something you need: don't remove Application Support or Containers folders blindly — they hold app data, not cache.
Do I need a RAM cleaner on Mac?
No. macOS manages memory itself. If it runs low, quit heavy apps and browser tabs or restart your Mac.
Should I use a cracked version of a paid cleaner?
No. A cleaner gets access to your whole disk, and a cracked build is code modified by someone unknown, with its signature broken and no updates. Use a free app or an official trial instead.
