Clean your Mac system with CleanMyMac X

CleanMyMac X’s System Junk module will clean up all the extra junk on your Mac’s operating system. It knows what to clean and what not to clean, making it incredibly safe. With CleanMyMac X, you’re in complete control of your Mac.

How does the System Junk module help me?

Well, when’s the last time you used one of your apps in Swahili? No? What about Tetum? Probably a no there, too. See, these are the kind of things that are on your system that you probably will never use (we’ll call them “junk”). There are tons of files like this on your Mac’s system, and CleanMyMac X helps you clean them all up.

Language Files

Language packs give your system and apps the ability to operate in multiple languages. Do you need 10+ languages for every single app installed on your Mac? Probably not.


A cache is a place where data is stored temporarily in order to help things load and run more quickly. Files in the cache eventually become outdated and begin to pile up on your Mac, resulting in decreased performance.

Log Files

A log file records the activity of an application, service, or process. However, sometimes these logs begin to pile up unnecessary information. If you’re a user who rarely sends crash reports, you can clean your user logs to increase app performance and save some space on your Mac.

Universal Binaries

A universal binary is a set of files that come with an application package. These files allow the app to run on two different types of Mac architectures, Intel and PowerPC. Your Mac only uses one of these two architectures, so the app files for the other architecture aren’t necessary.

Development Junk

Development junk is the group of support files that are created while installing an application on your Mac. When you install an app on your Mac, the app can create these support files to help aid it during the installation process. These files should be, and typically are, removed after the installation is over. However, sometimes they just plain aren't.

Broken Login Items

A login item is an app or service that should launch during startup. However, sometimes when you remove an app or service, it leaves a broken link as a leftover login item. These broken login items are useless and can take up valuable resources on your Mac.

Broken Preferences

Preference files can be found within application contents. They keep parameters that define how an app should operate. However, over time such files can be corrupted, and several things may be reasons for that: for instance, an app crash, a sudden blackout, or a hard drive corruption. Deleting preference files can make your apps operate correctly again.

iOS Photo Cache

This is a group of cache files found in your Photos Library (or Aperture Library). They’re located in a folder called iPod Photo Cache. When you sync photos to your iPhone, iPad, or iPod, iTunes creates this folder, where it then stores your cache files.

XCode Junk

If you develop your own applications, you know how much space Xcode and its supporting files gobble up. Cleaning up Derived Data, Module Cache, and other Xcode junk not only frees up storage space, but can also resolve build issues and warnings.

Industry experts talk about CleanMyMac X

I run CleanMyMac X weekly on my Mac mini M2 Pro to ensure things run smoothly, keep any bloatware in check, and reclaim purgeable disk space. Yes, I could do some of those tasks manually using the Terminal app; it’s much quicker with software and saves me time. CleanMyMac X is also useful for uninstalling and updating software.
