Mac’s are famously low on storage more often than not. Unless you’ve purchased a fully decked-out Mac with plentiful storage, chances are every now and then your Mac gets low on space. However, while trying to free up space on your Mac, you have probably seem something called “System Data” (or Other data). Well, if you’re wondering just what this is, and how to clean it off your system, read on. In this article, we will discuss what is ‘System Data’ in Mac storage, and how to delete it.
Even if storage is not an issue for your Mac, it pays to keep the unnecessary files at bay for the overall health of the system. Else, even a robust machine would struggle to deliver the best for you. The System Data storage on Mac requires special treatment and also a better understanding of how it accumulates a variety of files. So, we are first going to delve deep into how it functions and talk about the safer way to clean it up subsequently.

Which Types of Files are Included in System Data Storage on Mac?
For better storage management, macOS offers a handy tool to let you keep a track of storage consumption and also find out what categories have eaten up the most space. This is where the mysterious “Other” (or System Data in macOS 12 Monterey) appears in the Mac storage.
- Next, select the Storage tab to check your Mac disk space usage.
As macOS doesn’t clearly reveal what is included in this massive cluster, most of us are left scratching the head thinking what sort of files could be inside. Well, to unravel this mystery, the Mac System Data consists of a number of different files. They are:
Now, it’s crystal clear that the “Other” Mac storage label consists of miscellaneous files. Since it doesn’t fit into specific categories like Photos, Documents, Mail, or Messages, Apple represents it as “Other” or “System Data”. Since most of these files are useless and you may not need them any longer but need to be stored somewhere on your Mac, macOS dumps them all in a separate folder.
While this automatic storage management functionality is fine, what creates a hell of confusion is the lack of a straightforward way to dig into the System Data storage, check the files that are inside, and delete the ones that are no longer needed. Worse, macOS doesn’t offer much assistance about how to clean it up safely. And this is where it becomes rather painful for an average consumer.
Note: It’s worth pointing out that in macOS Big Sur or earlier, you will see “System” right above the “Other” storage. In macOS Monterey, System has been renamed as macOS and Other has been renamed as System Data.
Once you have figured out what sort of files are dumped into the System Data storage, you will likely be curious to check what’s in the Other storage on your Mac. In order to do that, you’ll have to dig into the Library folder on your Mac.
For those unfamiliar, the library folder on Mac is used to store a number of different files including app support files, app caches, preferences files, user account settings, and other important data that plays a vital role in helping the Mac function as it should. Be warned that making haphazard changes to your Mac’s library folder can damage the entire system. That’s the reason why macOS hides this folder by default. So, be sure to tweak this folder with extra care.
Next up, type in ~/library and press enter.
Here, you will see a long list of folders like Accounts, Caches, Audio, Assistant, cookies, and more. Now, you can dive into folders like Caches, Cookies, and Accounts to check what is inside. Again, make sure not to tinker with anything unknowingly as it might cause damage to the system.
How to Delete System Data Files on Mac
Now, you would be confronted with the big question, “Can you delete the Other storage on your Mac?”. The straightforward answer is “Yes” you can. But as I said above, you’ve got to be very careful while dealing with it.
To ensure you can recover accidentally delete files later, make sure to back up your Mac beforehand via Time Machine..
Best Mac Storage Cleaners You Should Try
Bear in mind that not all types of files are deleted permanently on Mac. That means even after you have deleted an app or any obscure files, your Mac storage will continue to have some remnants. But bother not, this is where the best Mac cleaner software packages come into play.
CleanMyMac has long been a trusted Mac storage cleaner. What I love about this software is the highly efficient analyzing feature that quickly digs deep into the Mac storage and highlights all the redundant files. Thus, it becomes quite easy for you to navigate through all the storage hogging useless files and clean them up with just a single click. While you do have to pay a premium to clean your Mac (the trial version only lets you diagnose your device) using the CleanMyMac, it’s worth the money you pay given the high efficiency.

If you are looking for a relatively affordable Mac storage cleaner, DaisyDisk could be a safe bet. The app presents a detailed breakdown of your disk space, showing all the unnecessary files that you can delete to restore a ton of precious storage on your Mac.

Another Mac cleaning software package that has managed to catch my attention is Mac Cleaner Pro. It comes with a bundle of six storage cleanup tools that are designed to let you wipe out useless files and speed up your Mac. The software features a powerful disk space analyzer that helps you keep a tag of redundant files and clean them up easily. But what has impressed me the most is the “Funter” aka the hidden files manager that enables you to quickly find out the files that are out of sight.
