Top 10 best cleaners for Mac: Free and premium versions

1. CleanMyMac X

CleanMyMac X takes the first place with good reason — this cleaner combines features of both cleaning software and antimalware tool. Its Smart Scan promises a “nice and thorough scan of your Mac.” It does what it says, detecting junk like user cache files and system logs, checking your Mac for malicious software, and speeding up your MacBook. Looks like, there is a threat in my system, that I need to get rid of:

Frankly speaking, CleanMyMac X is Tesla Roadster among other Mac cleaners.

2. Disk Doctor

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 2020, it still looks like a useful tool for Mac cleaning that removes junk slowing down and reducing the computing power of your Mac.

Price: $2.99
Free version: N/A

3. MacBooster

MacBooster is a popular app that is developed at IObit. It cramps so many features under one interface it hardly fits into a “cleaner” niche. What makes it different is the duplicate file remover — an extra option to free up space on Mac. According to the developer, you can altogether delete 20 types of junk files with MacBooster.

MacBooster, in its version 8 rendition, offers real-time Mac protection, which makes it also an antivirus, although, quite a basic one. For example, you can remove malicious browser cookies to evade intrusive advertisements on your Mac. It doesn’t belong to free Mac cleaner apps per se, although a free trial is available. Unlike CleanMyMac, it doesn’t allow you to remove any junk for free in its trial version. To get the taste of MacBooster, you only have to rely on a free scan.

You should know that even when you uninstall MacBooster, some parts of the app may remain on your drive.

Price: $59.95 for Premium version
Free version: Available

4. Onyx

OnyX is a french Mac cleaning solution developed by Titanium software. It weighs only 5 MB but that doesn’t mean its capabilities are limited. OnyX is a tool that programmers will have a lot of fun with. With it, you can peek under the hood of your macOS and automate a whole list of jobs, like disk cleanup and cache removal. You can even tweak the color of folders on your Mac, and even make them invisible. Deservedly, it's among best free Mac cleaners.

OnyX is one of the best Mac cleaners because it cleans many specific under-the-surface files, like inner databases and logs. If you know what is XPC cache is, you’ll probably like this app. But for us, ordinary Mac users who came here for the design and glossy buttons, OnyX will require some learning time.
Those who use OnyX say it is stable and reliable. There is no dedicated customer service (because OnyX is free software), but you shouldn’t be worried. The only likely damage is you accidentally deleting files by yourself.
Price: Free cleaner

5. DaisyDisk

DaisyDisk gives you a visual representation of your Mac folders, making it easy to see what is taking up space and delete the folders you don't need. All you need to do is select a drive, DaisyDisk will scan it, then you can delete everything that is wasting valuable space. It comes with a free and premium version.

Price:$9.99
Free version: Trial version available

6. 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

7. 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.

Free version: Demo available

8. 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. Also note that Drive Genius is not available for macOS Catalina (as of the beginning of 2020).

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

9. 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

10. 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
