If you only want to do one thing, you probably do not need CleanMyMac. To uninstall apps completely, the free AppCleaner is enough. To see what is eating your disk space, DaisyDisk does it. For system maintenance, OnyX is free. Each of these tools does one job. What CleanMyMac adds is cleanup, uninstalling, large files and malware scanning in a single window, so the real question is whether you want that bundle.
First, where we stand: Appicker is an authorized MacPaw reseller and sells CleanMyMac, so we gain if you buy it. I run Appicker and have used CleanMyMac myself, but not the three alternatives below. For them we only report what their own sites and public third-party sources say, with no impressions of our own. DaisyDisk is also listed in our store but is out of stock right now, so there is no buy link for it. We will not tilt the verdict toward CleanMyMac because we sell it.
Which kind of tool do you need?
macOS already includes tools that handle a lot of this. Apple's Storage settings show what uses your space and suggest cleanup. Our guide to freeing up disk space on a Mac covers the free steps. Third-party tools are for the places where the built-in ones are awkward.
| CleanMyMac | AppCleaner | OnyX | DaisyDisk | |
|---|---|---|---|---|
| Main job | Cleanup, uninstalling, large files and malware scan in one app | Uninstall apps and their leftovers | System maintenance, clearing caches, rebuilding system databases | Show what uses your disk space as a chart |
| Free? | No, 7-day trial | Yes | Yes | No, free trial |
| Malware scan | Yes (MacPaw's own engine) | Not mentioned on its site | Not mentioned on its site | Not mentioned on its site |
| Ease of use | Easy | Easy | Harder | Easy |
"Not mentioned on its site" means we found no description of that feature there. It does not prove the feature is absent. The "Main job" and "Free?" rows come from each product's own site or the third-party sources linked below. "Ease of use" is our judgment from how the sites describe the tools, not a test result.
CleanMyMac: who it suits and who it does not
CleanMyMac 5 groups its tools into Cleanup, Protection, Performance, Applications, My Clutter and Space Lens. Together they cover system junk, uninstalling apps with their leftovers, large and duplicate files, and a malware scan.
Strengths: one window for all of that, so you do not switch between tools. I have used it myself and found it smooth and good looking. It digs deeper than macOS's own storage page, which leaves a lot out. That is personal experience, not test data.
Limits: it is paid software. Much of the "junk" it finds is cache that apps rebuild, so some of the space can come back within days. The malware scanner is MacPaw's own, and we did not find a published score from an independent lab, so do not treat it as a replacement for the protection built into macOS. More in our CleanMyMac review.
AppCleaner: just uninstall apps cleanly
AppCleaner is made by FreeMacSoft. Its site describes it as a small application for thoroughly uninstalling unwanted apps. Installing an app scatters files around your system, and AppCleaner finds those small files and deletes them safely. You drop an app onto its window, it lists the related files, and you click delete.
Strengths:
- It is free. OWC's blog calls it a completely free application.
- It is simple and does one job: drop, review, delete.
Limits:
- It only uninstalls. Its site does not mention clearing system caches, finding large files or scanning for malware, so you need other tools for those.
- It is offered in separate downloads by macOS version (3.7 for macOS 15 and later, 3.6.8 and others for older systems), so match the download to your system.
Who it fits: anyone who only cares about removing apps without leftovers. You do not need to pay for that.
OnyX: free and deep, but read before you click
OnyX is made by Titanium Software. Its author says he has spent a great deal of time developing it since 2003 so that all Mac users can use it for free, and he accepts donations. The site describes OnyX as a multifunction utility that can verify the structure of system files, run cleaning and maintenance tasks, uninstall applications, configure settings for the Finder, Dock and some Apple apps, delete caches, and rebuild various databases and indexes.
Strengths:
- It is free.
- It covers many maintenance tasks. The site says these would otherwise need complex commands typed into the command line, and OnyX gives you a graphical interface for them.
Limits:
- There is a specific version of OnyX for each major macOS version, and the site warns you to use the right one and not a version meant for an earlier system.
- The site does not mention a malware scan.
- With that many options, some are not obvious. This is our judgment, not the site's: if you do not know what a maintenance task does, do not run it yet.
Who it fits: people who are willing to read the descriptions and want a free maintenance toolkit.
DaisyDisk: see what is taking the space
DaisyDisk's site says it scans your computer and shows what uses your storage as colorful rings that you can drill into by files and folders. Only you decide what to delete, and system files are protected automatically. It lists macOS 10.13 or newer, supports Apple silicon and Intel, and offers a free trial.
Strengths:
- It is visual. Spotting the biggest items in a chart is faster than opening folder after folder.
- Its site argues that macOS can look after caches by itself and that the real space is in large files you no longer need, so it does not clear caches and lets you choose which big files to delete. That is the vendor's position, not a third-party finding, but it matches what we say in our own guide: cache space often comes back, while large files stay gone.
Limits:
- It is paid. Check its site for the current price, which we do not quote here.
- It only deals with disk space. It does not uninstall apps with leftovers, scan for malware or run maintenance tasks.
- You make the deletion decisions. Its site says files are deleted permanently, so check before you remove anything.
Who it fits: people whose disk is nearly full and who want to find the big items at a glance.
Is a free option enough?
For many people, yes.
- You only need free space: start with macOS's built-in Storage settings, then use DaisyDisk if you want to see where the bulk is.
- You only want to uninstall apps: AppCleaner.
- You want regular maintenance: OnyX.
- None of the above sounds like you: then you probably do not need CleanMyMac either.
When does CleanMyMac make more sense?
- You want one app and one interface for cleanup, uninstalling, large and duplicate files and a malware scan, without learning three tools.
- You are willing to pay for the convenience.
- You accept that it is paid software, either a subscription or a one-time purchase. The difference between the 1 Year and the lifetime option is in How Much Does CleanMyMac Cost?
