CleanMyMac X by MacPaw is an award-winning Mac cleaner with such a well-designed user interface that you’ll look forward to using it. With a single click, the app can find all unwanted and unnecessary files scattered across your system drive, detect potential malware threats, and optimize your Mac’s performance by freeing up RAM, running maintenance scripts, and more.

Regardless of whether you use CleanMyMac X as a simple storage cleaner or explore some of its more advanced features, you can always rest assured, knowing the app will never accidentally delete important files or make your Mac unbootable because it’s been designed from the ground up for maximum safety and reliability.

Key features:

  • One button cleanup – Thanks to its Smart Cleanup feature, CleanMyMac X can automatically run all cleanup processes in the optimal order, requiring you to make only a single click.
  • Malware removal – Besides junk files occupying precious storage space, CleanMyMac X can also detect and remove dangerous files and apps.

mac cleaner

Overview:

If you’ve ever needed to recover accidentally deleted or otherwise lost files from your Mac or an external storage device, then you might already be familiar with this Mac file cleaner. That’s because Disk Drill is best known as powerful data recovery software capable of undeleting over 400 different file formats, including all common document, image, video, and audio formats.

However, Disk Drill is also an excellent Mac file cleaner, and you can use it to find duplicates, securely delete sensitive files, and erase free disk space so that even files that have already been deleted can’t be recovered (not even with Disk Drill). Best of all, you can try everything Disk Drill has to offer for free on any Mac running Mac OS X 10.11.6 or newer (including macOS 11 Big Sur).

Key features:

  • Data recovery capabilities – Disk Drill stands out from other free Mac cleaners featured in this article because it can recover permanently deleted files that are no longer present in the Trash folder.
  • Backup features – You can use Disk Drill to protect important files or create byte-to-byte disk backups that make it possible to recover even from the most serious data loss situations.
  • Cross-platform – Disk Drill runs on both macOS and Windows, and a single license lets you activate it on up to 3 different devices.

  • Data recovery capabilities
  • Intuitive user interface
  • Fully compatible with macOS 11 Big Sur
  • Many useful cleanup features available for free
  • Great performance

Overview:

CCleaner is a popular storage cleaner capable of instantly deleting your internet cache, history, and cookies, the Trash folder, mentions of recently opened documents, and unnecessary files leftover by all kinds of third-party apps.

Even though CCleaner hasn’t been updated in a while and doesn’t officially support the latest version of macOS, it still runs fine and does exactly what it promises to do while being completely free. That said, a paid version of CCleaner is available, and it adds real-time monitoring, automatic updates, and premium support.

Key features:

  • Customizable – Ccleaner allows you to specify which junk files you want to clean up and which you want to leave behind.

Unlike many other Mac cleaning software solutions listed in this article, DaisyDisk is a one-trick pony that does one thing and one thing only. While definitely a downside if your goal is to perform in-depth Mac cleaning to achieve the best performance possible, the lack of features and options does make DaisyDisk very easy to use.

Key features:

  • Fast scanning – If you have a modern SSD, then you can expect DaisyDisk to scan it in just a few seconds.

5. Clean Me

macbook cleaner

Overview:

Clean Me is an excellent open-source disk cleaner that’s as effective as it is simple. The app presents you with a list of toggles, each of which lets you clean a specific folder, such as the Trash folder or your User Cache. You simply need to make your selection and click Analyze to determine the amount of storage space that can be freed up. Then, you can click Clean to delete everything in one go. The only downside is that you can’t install Clean Me from the Mac App Store. Instead, you need to use Homebrew, an open-source package manager for macOS, or compile the software yourself, which takes some time and skills.

Key features:

  • Secure – Clean Me doesn’t store your admin password in any way, and it also doesn’t request an internet connection.
  • Open-source – Because Clean Me is open source, you can study its source code and verify that it does what it promises to do.

free mac cleaning software

Overview:

OnyX is a toolbox filled with system optimization and cleanup tools. It has been around for quite some time now, and there are many Mac users who swear by its reliability and clean interface, which makes it very easy to perform optimization tasks that would otherwise require complex commands to be entered into the Terminal.

Interestingly, there’s a specific version of OnyX for each major version of the operating system. In other words, you can’t use, for example, OnyX 3.8.7 on macOS Big Sur because that version works only on macOS Catalina. The good news is that a version for Big Sur is already available, and all older versions can be downloaded directly from the official website.

Key features:

  • System integrity verification – OnyX can intelligently verify the integrity of system files to help you ensure that they haven’t been damaged during a system update or after a malware infection.

That’s right, Smart Mac Care can scan and remove all known malware infections and unwanted apps from your Mac to prevent cybercriminals from stealing your personal information.

How to Choose Mac Cleaner That Really Works?

The last thing you want is to choose a Mac cleaner that works so poorly that your Mac ends up being even slower than it was before. What’s even worse, some Mac cleaners are infected with dangerous malware that can cause your Mac to display highly inappropriate ads, run cryptomining software, or expose your personal information to strangers with malicious intentions.

Here’s what you need to pay attention to when choosing Mac cleaning software:

👩‍💻 Developer: You should always check who’s behind the Mac cleaner you’re about to download. Unfortunately, not all Mac cleaners are developed by people who have your best intentions at heart. By choosing a Mac cleaner from a trusted developer, you can avoid all kinds of performance and customer support issues.

Reviews: It’s one thing to promise things like one-click junk removal or cache optimization, and it’s something else to actually deliver on these promises. That’s why it’s a good idea to check user reviews and find out what real users have to say.

🆕 Updates: The best Mac cleaner software receives updates on a regular basis to fix known issues, introduce new functionality, and maintain compatibility with macOS. Updates are especially important when it comes to paid Mac cleaners because you shouldn’t have to put up with bugs that prevent you from enjoying the app properly.

Performance: There are many different Mac cleaning software apps, and they all offer different sets of features and functionality. Some focus predominantly on freeing up storage space, while others lean more toward system optimization. Regardless of which kind of Mac cleaning software you choose, make sure to verify that it actually performs well and does what it promises to do.

💲 Price: Not all free Mac cleaners are 100% free. Some are only free to try, requiring you to purchase a paid license to unlock unlimited cleaning. Moreover, some paid Mac cleaners require you to purchase a monthly or annual subscription, which can end up costing you quite a lot of money in the long run.

Of course, you can always simply pick one of the top 15 free Mac cleaner software apps featured above and rest assured, knowing that it can get the job done without exposing your Mac to malware.

Are All Mac Cleaners Safe to Use or You Should Avoid Any?

Unfortunately, not all Mac cleaners are safe to use, and there are definitely some apps that you should avoid at all costs.

For example, Advanced Mac Cleaner is a known deceptive Mac cleaner that promises to enhance performance and remove junk files. This app performs a fake scan that always results in multiple issues being discovered. When users attempt to fix the detected issues, they quickly discover that the free version is unable to do so. The app then encourages them to upgrade to the full version, effectively trying to scam them out of money.

Other dangerous Mac cleaners that you should avoid at all costs include CompariShop, MacBright, and TURBOMAC. Should you ever accidentally install one of these Mac cleaners, uninstall it as soon as possible and use third-party antivirus software to verify that no other malware is left on your Mac.

Summary

We hope that our list of the top 15 free Mac cleaner software available in 2021 has helped you find at least one app that meets all your requirements, allowing you to restore your Mac to its former glory. Just make sure to use it on a regular basis, and you should be able to avoid common performance and stability issues caused by insufficient storage space, unnecessary apps, and leftover files.
