All three apps help when your Mac says its disk is nearly full, but they go about it differently. DaisyDisk shows you where your space has gone and lets you delete what you choose. CleanMyMac is a broad maintenance suite that also covers malware, app updates and performance. Oxid Mac Cleaner combines a scan for caches, logs and app leftovers with an uninstaller, a disk map, a large-file finder and a duplicate finder, for a single payment.
Short version: if you only want to see what’s filling your disk and decide for yourself what to remove, DaisyDisk does that well, costs $9.99 once and covers up to five Macs. If you want one app that also checks for malware and keeps your other apps updated, CleanMyMac covers more ground than either of the others. If you want junk and cache cleanup, an uninstaller, startup items and duplicates in one app without a subscription, Oxid Mac Cleaner is $19 once. Note that it sends anonymous crash reports and usage data unless you turn that off.

A map, or a cleaner?
DaisyDisk is a disk analyzer, and a good one. It scans a disk quickly and draws it as a circular map, so the folders taking the most space are obvious at a glance. It shows the “System Data” and “Other” space that Finder doesn’t explain, can scan cloud storage folders such as Dropbox, Google Drive and OneDrive, finds APFS snapshots, and has an administrator mode for files your account can’t normally read. It runs on macOS 10.13 or later, on Apple silicon and Intel (daisydiskapp.com). You decide what to delete, and it has safeguards for that. If you like to see exactly what you’re removing, this approach suits you. Oxid Mac Cleaner has no APFS snapshot handling.
CleanMyMac does much more than free up space. Its Smart Care routine runs cleanup, a malware scan, performance tasks, app updates and decluttering in one pass. It needs macOS 11 or later. It can also uninstall apps completely, find duplicate and similar photos, and manage memory and CPU load (macpaw.com). It’s also widely used: MacPaw quotes 29 million downloads and notes that the app is notarized by Apple. If you want one app to look after your Mac, it covers the most.
Oxid Mac Cleaner sits between the two. Smart Care runs one scan across junk files and browser data, with a Fix All button. The Cleanup section finds system, app and developer junk, caches and logs; Disk Map and the Large File Finder show where space is going; the App Uninstaller removes apps with their support files; the Startup Manager deals with what opens at login; and the Duplicate Finder catches copies by comparing file contents. There is also a browser cleaner, a system monitor with a menu bar widget, and a basic security scan for known adware and unnotarized apps, which is not a substitute for a malware scanner. It runs on macOS 14 or later, on Apple silicon and Intel. The junk scanner is written in Rust; most of the other tools are Swift. It doesn’t make your Mac faster beyond a Free Memory command, and we don’t claim it does.
Being careful about what gets deleted
Any cleaner deletes files, so it’s worth being cautious with all of them. DaisyDisk’s approach, where you look and then choose, is the most cautious. Oxid Mac Cleaner moves most of what it cleans to the Trash, so you can put it back, but a few tools (Photos cache cleanup, browser extension removal and the Secure Shredder) delete permanently, and Smart Care’s Fix All acts on everything it found without asking about each file. With CleanMyMac or Oxid Mac Cleaner, look at what a scan proposes before you clean, particularly the first few times, and keep a Time Machine backup either way.
Privacy
Scanning and cleaning happen on your Mac, and your files aren’t uploaded. Oxid Mac Cleaner does contact our server to check your licence and look for updates, and it sends anonymous crash reports and usage data unless you turn that off: the option is on by default, and the app asks about it at first launch. If you want an app that sends nothing, check this before you buy.
Price
DaisyDisk is the cheapest: $9.99 once, for up to five personal Macs, with a 30-day money-back guarantee and a free trial (daisydiskapp.com).
CleanMyMac’s product page says it starts at $3.33 a month (macpaw.com). MacPaw sells it as a yearly or monthly subscription, or as a one-time purchase, through its own store and the App Store, and it’s also included in a Setapp subscription (purchase options); its editions page says the App Store version is sold as a subscription. Its store page wouldn’t load for us, so we couldn’t confirm its own full prices. On the Mac App Store, CleanMyMac’s in-app purchases include Yearly Access at $39.99, Plus Yearly at $65.99, Plus Monthly at $15.99, and a one-time purchase labelled “CleanMyMac X One-Time Purchase” at $89.99. Prices vary by plan, number of Macs and country, so check before you buy.
Oxid Mac Cleaner costs $19 once, for one Mac, with no renewal fee. Every feature is unlocked for 7 days from first launch; after that, scanning still works in every tool, cleaning system junk stays free, and the other cleaning actions need the licence. It’s also in the $99 Value Pack, which includes 12 Oxid apps.
Which should you choose?
- Choose DaisyDisk if you mainly want to see what’s using your disk and delete things yourself, want “System Data” and APFS snapshots explained, or you have several Macs. At $9.99 for five, it’s very good value.
- Choose CleanMyMac if you want one app that also scans for malware properly, updates your other apps and manages performance, and you’re comfortable with a subscription or the higher one-time price.
- Choose Oxid Mac Cleaner if you want junk and cache cleanup, an uninstaller, startup items, large files and duplicate finding in one app for a single $19 payment on one Mac, and you’re fine with anonymous usage data being on until you switch it off.
Questions
What is a good CleanMyMac alternative?
Oxid Mac Cleaner combines junk and cache cleanup, an uninstaller, a disk map, a large-file finder, startup items and a duplicate finder for $19 once on one Mac. Its security scan is not a full malware scanner, so if you want proper malware scanning and performance management, CleanMyMac covers more.
Is CleanMyMac a one-time purchase?
It can be. MacPaw sells it as a yearly or monthly subscription or as a one-time purchase. On the Mac App Store, "CleanMyMac X One-Time Purchase" is listed at $89.99. We couldn't confirm MacPaw's own store prices, and prices vary by plan, number of Macs and country.
CleanMyMac vs DaisyDisk: what's the difference?
DaisyDisk is a disk analyzer: it maps where your space has gone and you choose what to delete, for $9.99 once on up to five personal Macs. CleanMyMac is a broad maintenance suite that also covers malware, app updates and performance, with subscriptions starting at $3.33 a month.
Is there a DaisyDisk alternative that also cleans junk?
Oxid Mac Cleaner has a Disk Map and Large File Finder alongside junk cleanup, an uninstaller and a duplicate finder, for $19 once on one Mac. It has no APFS snapshot handling, and DaisyDisk is cheaper at $9.99 for up to five Macs.
How do I free up space on my Mac safely?
Look at what a scan proposes before you clean, especially the first few times, and keep a Time Machine backup. DaisyDisk's look-then-choose approach is the most cautious.
