CleanMyMac X takes the first place with good reason — this cleaner combines features of both cleaning software and antimalware tool.

Disk Doctor is developed in the UK and was awarded the 'Mac Gem’ award by MacWorld in 2013. CNET and other tech journalists also praise functionality. As of 2021, it still looks like a useful tool for Mac cleaning that removes junk slowing down and reducing the computing power of your Mac.

3. Gemini 2

Gemini 2 is the duplicate finder that allows you to free up gigabytes of storage and organize your files. In just a few minutes.

It quickly scans every corner of your Mac and weeds out useless copies. No matter what type of file it is: a photo, music track, or a doc… Gemini will definitely find it. And once the scan is done, you can remove the duplicates in a click. Or review results to make sure nothing important gets deleted.

If you remove something by accident, it takes just a click to put it back. And to make sure things like that never happen again, you can exclude specific files and folders from scan. Try out the free version right here.

The app has seen a major update in 2021 which included a real-time duplicate monitor. This new tool notifies you of duplicates the moment they are created on your Mac.

5. AppCleaner & Uninstaller

If you only need to uninstall apps on Mac, AppCleaner is a good pick. AppCleaner only removes applications, plugins, and widgets, which are again, small apps. AppCleaner works in a familiar drag & drop mode. Its interface is also clean and easy to understand for a newbie.

After feeding the apps to AppCleaner, you should visit the Leftovers section of the app to erase their remains. Why we place AppCleaner & Uninstaller among free Mac cleaner tools? Because it is 100% free. Whether you will fully clean your Mac using it, is a different question.
AppCleaner & Uninstaller is created by FreeMacSoft, also the makers of LiteIcon, an icon customizer for Mac.
Price: Voluntary donation

6. Smart Mac Care

If you launch Smart Mac Care, it will look hauntingly familiar to other free Mac cleaner apps. Not only features will be called the same, everything up to the fonts, will be identical to some other app you’ve just used. That’s not a minus, though. You can still free up a lot of space with Smart Mac Care.

Smart Mac Care operates by a logic of “scans.” There is a Junk Scan, Malware Scan, Privacy Scan, etc. Just like Mac Booster, Smart Mac Care removes duplicates scattered in various locations on your Mac. There’s also a Memory Optimizer feature that promises to free up RAM on your Mac. In a word, Smart Mac Care resembles every other generic product whose only difference is in packaging. This is supported by the fact that we couldn’t find any credible third-party reviews for this app.

On another skeptical note: to uninstall Smart Mac Care you have to enter your admin password. This is not the case with other Mac cleaners we’ve used.
Price: $56.62 per year
Free version: Demo available

7. Drive Genius

Drive Genius is labeled a “Mac monitoring software.” It’s a whole suite of tools that provide powerful disk diagnostics. It’s hard to list a thing that this software doesn’t do. You can scan for malware, secure-erase files, customize icons — it’s dozens of apps in one body. What makes Drive Genius unique is, probably, its search for corrupted files and inconsistencies on your drive. If your Mac is an old one, keeping it in good health will be easier with Drive Genius.

In a free version, you can use just a fraction of tools, notably a DiskPulse utility. This is an automatic Mac health checker that notifies you before your hard drive fails. Unlike Mac cleaners that merely scan, it is able to repair damage on your disks, which makes it a real deal. Be prepared that hard drive scan may take some time, but the results are worth it. The latest version of Drive Genius released in 2020 adds long-awaited support for macOS Big Sur.

Price: $299 for Professional edition
Free version: Limited Lite edition is available

8. CCleaner

Originally created in 2004 by Piriform, CCleaner comes with a free and professional version, focusing on businesses and business customers. CCleaner is a cross-platform tool, for PCs, Macs, Android, and it has a Cloud, Network and Technician tool, depending on what you need and the platform/software you use.

The premium version comes with a lot more features, including real-time alerts, free updates, and dedicated support. Although created for PCs in the early days, CCleaner does well to identify unwanted files on a Mac, so that users can select and delete the files and folders they don't need to free up space. As a cleaner for Mac, customers are pretty happy with the results of CCleaner.
Price: $19.95
Free version: Available

9. Sensei

The Sensei app is a relatively new app on the market, but it can be another useful tool for your Mac. The Sensei software developers call the app “Pro Mac Cleaner” on their website. I would call it a performance controlling tool.

Sensei presents a detailed picture of how your Mac performs. In the Dashboard, you can find out information about your MacBook, check your CPU’s current temperature, and see how much of your RAM is used. Cooling gives you exact information on your Mac’s fans' speed.

Its Clean option helps to get rid of user cache, logs, large files, etc. The Uninstaller feature allows you to delete apps from your Mac and remove their traces. It doesn’t list pre-installed apps from Apple, such as Safari or Calendar, but it shows every app you have installed on your Mac.

Surely, you can clean up your Mac manually, but using dedicated software will save you tons of time.

Price: $29 per year

OnyX is one of the best Mac cleaners because it cleans many specific under-the-surface files, like inner databases and logs.

12. Native macOS cleaner (Optimize Storage)

Your macOS has its own cleaner of sorts. You’ve probably come across it when checking your occupied disk space.
Go to Apple menu.
Now, click About this Mac > Storage > Manage.

In the sidebar you’ll see the main categories of files on your Mac. Going through Documents is likely to be the most fruitful option. Check the Size and click on Last Accessed. Now you’ve found all those movies gathering dust in your Downloads.
In the same way you can delete some old apps. This feature is could be an alternative to a free Mac cleaner; the only problem is it works largely on the surface. You won’t be able to remove System Junk or analyze the grey areas occupied by “Other.”

• The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps might show storage categories such as Not Mounted, VM, Recovery, Other Volumes, Free, or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
• When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
• If you're using a pro app and Optimize Mac Storage, learn how to make sure that your projects are always on your Mac and able to access their files.
