Do you still remember how snappy your Mac felt when you booted it up for the first time? If you’ve been using it for a while, it probably doesn’t feel nearly as responsive anymore. That’s because Macs—just like all other computers—accumulate all kinds of junk over time that slows them down, including leftover files, old settings, and duplicate apps.
If you believe that starting from scratch by reinstalling your Mac is the only way to restore its original performance, you’re wrong. All you need to make your Mac feel new again is one of the top 10 best free Mac cleaners described in this article.

1. Disk Drill
Disk Drill is actually a data recovery software first and a Mac file cleaner second, but that doesn’t stop it from ranking high on our list of the top 10 best free Mac cleaners. That’s because it comes with a truly unlimited free cleanup module that makes it possible to easily identify and visualize all files that are taking up a lot of space and get rid of them in an instant.
If you’re worried that an important file could find its away among junk files, then you can filter the scan results by file type, keywords, file size, and several other criteria and manually verify that the files you’re deleting are really unnecessary. That said, Disk Drill is a trusted Mac cleaner, so you can leave everything up to it and save yourself valuable time.
As we’ve already mentioned, Disk Drill excels at recovering lost files after an accidental deletion, hardware failure, or some other data loss incident. The app can recover over 400 different file formats, and the data recovery process is so straightforward that even less experienced users can figure it out on their own.
- Comes with unlimited Mac clean up tools
- Intuitive user interface
- Frequently updated
- Powerful data recovery functionality
- Doesn’t come with an app uninstaller
2. CleanMyMac X
When it comes to Mac cleaners, you would be hard-pressed to find a more popular solution than CleanMyMac X by MacPaw. This feature-packed app boasts a polished user interface and a whole host of useful cleaning features, making it possible to get rid of junk in all corners of your macOS with a single click.
CleanMyMac X offers a variety of easy-to-use tools that can quickly free up space on your device and get rid of suspicious files.
CleanMyMac X is able to tell useful files from those that can be safely deleted thanks to the constantly updated Safety Database.

In addition to performing deep system cleaning, CleanMyMac X can neutralize malware threats, tweak various system settings, uninstall or reset apps, and securely delete sensitive files. Users can try all features for free and unlock unlimited junk removal for $34.95.

Formally known as Dr. Cleaner, this well-rated Mac cleaner is developed by Trend Micro, an American-Japanese multinational cybersecurity software company known primarily for its cybersecurity solutions. As its name suggests, Cleaner One Lite is the free version of Cleaner One Pro, which means that it lacks certain features that some users may find important.
To be more specific, Cleaner One Lite doesn’t include a duplicate file scanner, system status monitoring, similar photo finder, start-up manager, app manager, file shredder, and security center. If these features are important to you, we recommend you pick another free Mac cleaning software solution from our list.
But if you’re looking for a basic Mac disk cleaner that can clean an unlimited amount of data from your Mac, Cleaner One Lite is a solid choice, and its Mac App Store reviews speak for themselves.
- Well-rate Mac storage cleaner
- Easy-to-use interface
- Creates a visual and interactive map of junk files
- Some features are available only in the Pro version.
Ccleaner for Mac is an easy-to-use Mac disk cleaning tool that shares most features with its incredibly popular Windows counterpart. Originally released in 2004 by Piriform, Ccleaner has helped countless users fix annoying slowdowns, reduce clutter, and delete potentially sensitive cookies and other leftover files.
Through this app’s intuitive interface, you can select where to scan, and then view the type and number of items the scan detected before they are deleted.
Ccleaner for Mac is fully customizable, giving you the flexibility you need to improve the performance of your Mac. You can specify exactly what you want to clean, such as Safari data, Trash, recent documents, and so on. Of course, you can also choose to clean all junk files in one go, which is the recommended approach when cleaning applications and system files for the first time.
Unfortunately, Ccleaner for Mac hasn’t been updated in a while, and doesn’t officially support the latest version of macOS. That said, we’ve been able to install and use the latest version of Ccleaner for Mac on macOS Catalina just fine.
- Completely unlimited cleanup
- Selective cleaning
- Erases browsing history
- Not officially compatible with the latest version of macOS
- Lack of updates
5. Clean Me
Clean Me is an open source cleaner for Mac that started as a personal project and gradually evolved into a compelling alternative to the best disk cleaners for Mac. It can clean everything from the Trash folder to downloaded mail attachments, document revisions, app, user, and system caches, spotlight indexing data, system logs, and more.
The app has only one window, and it contains all options you need to get rid of all junk that’s slowing down your Mac and preventing it from performing to its full potential. By default, Clean Me doesn’t analyze cache files, and its creator advises against deleting them because cache files make apps run faster. But if you would like to delete them anyway, all you need to do is check the corresponding option.
The only thing we don’t like about Clean Me is the complicated installation process, which requires you to either use Homebrew or install the app manually via the releases on its GitHub repository.
- Open source
- Completely free
- Simple to use
- Installation could be easier
MacClean is a good Mac cleaner that you can trust with restoring your computer to its former glory. Instead of cleaning all junk files in one go, MacClean offers five distinct cleanup options: System Junk, Internet Junk, Malicious Cookies, Privacy Issues, Security Issues. The first option is the one you’ll probably use the most because it removes user and system junk, unnecessary development files, and app leftovers.
If you want to get rid of duplicate files, you need to rather confusingly select Cleanup Tools under utilities. That’s where you can also find the option to remove outdated language files or the option to securely delete sensitive files. Unfortunately, it’s not possible to run all cleanup features MacClean has to offer with a single click.
Compared with other free cleaning apps featured in this article, scanning with MacClean definitely takes more time, but at least the results are worth the wait. The bad news is that scanning is the only thing the free version lets you do, and you need to purchase a license to delete found junk files.
- Comes with a duplicate finder
- Offers multiple ways to remove junk files from Mac
- The full version is affordable
- No comprehensive one-click scan
- The free version lets you only scan your Mac
- Scanning takes some time
Developed by the company behind Stellar Data Recovery, Stellar SpeedUp Mac is an advanced Mac cleaner that stands out from the pack with its ability to optimize system memory.

In most cases, the real-world performance impact is negligible, but refreshing system memory can solve certain rare problems caused by memory-hungry apps.
As any hard drive cleaner should, Stellar SpeedUp Mac can quickly and efficiently identify duplicate files and delete them to free up valuable disk space. If you’re really low on storage space and desperate for every single megabyte, then you can search specific languages and associated apps and remove them in one go.
The free version of Stellar SpeedUp Mac can do just about everything the full version can, but only for 30 days. Once the free trial period ends, you have to purchase a license to continue using the software.

DaisyDisk is certainly one of the most beautiful apps to clean Mac. Its goal is to solve a common issue that most Mac users encounter at one point or another: insufficient disk space. When you launch the app, it gives you an overview of all storage devices attached to your Mac, including network storage. You can simply click the Scan button next to each storage device to analyze its usage.
All files and folders are displayed as a visual interactive map that makes it crystal-clear where the largest files are located. The visual nature of DaisyDisk makes it incredibly easy to free up storage space and avoid an expensive purchase of a new storage device.

Are Mac Cleaners Safe to Use?
Generally speaking, Mac cleaners are perfectly safe to use because they’re designed to get rid of unnecessary junk files and nothing else. The trick is that you need to select a reliable Mac cleanup software that does what it’s supposed to do and avoid Mac cleaners that haven’t been updated in a long time or exist only to scam Mac users.
Here are some signs that your Mac cleaner is not safe to use:
- The cleaner is warning you about a malware infection and wants you to pay money for its removal.
- The cleaner wants you to install additional software programs to clean Mac of junk files.
- The cleaner aggressively pushes a subscription or premium license.
If you stick to the top 10 best free Mac cleaners described in this article, then you shouldn’t run into any of these issues.
