So, your Mac is running out of storage. You try to figure out what’s taking up your disk space by clicking the Apple logo on the top-left of the screen, selecting About This Mac, and hitting the Storage tab.

You'll be greeted with a color-coded categorization of what your disk is being used for.
To your surprise, you see a yellow bar representing “System” that seems to occupy way more space than you think it should. In the example above, it only shows 207 GB, but take a look at this Apple discussion — some Mac users report that System Storage takes an astonishing 250 GB.

Worse yet, you have no idea what’s included in “System” storage, because clicking the “Manage” button brings you to this System Information window… and the “System” row is greyed out.
Why does my Mac system require so much space?
What does it contain?
Is it safe to remove some of those system files?
How do I regain more storage space?
Questions like these may easily get to your head. Although my Mac now has a good amount of disk space available, I’m always wary of files that are taking up more space than they should.
I have no idea why “System” is greyed out while “Documents,” “System Junk,” “Trash,” etc. allow you to review the files based on size and type. My hunch is that Apple does this on purpose to prevent users from deleting system files that could lead to serious issues.
What Files Are Included in System Storage on Mac?
During my research, I found many people report that Apple counts iTunes backup files and app caches (e.g. Adobe video cache files) in the System category.
Since it’s greyed out and we are unable to click on that category for deeper analysis, we’ll have to use a third-party app to assist.
CleanMyMac X is perfect for this kind of analysis. Since I tested the app in our best Mac cleaner review, it immediately came to my head when I saw “System” was greyed out in Storage. Note that CleanMyMac isn’t freeware, but the new “Space Lens” feature is free to use and it allows you to scan your Macintosh HD, and then show you an in-depth overview of what’s taking up disk space on your Mac.
Step 1:Download CleanMyMac and install the app on your Mac. Open it, under “Space Lens” module, first click the yellow “Grant Access” button to allow the app to access your Mac files and then select “Scan” to get started.
Step 2: Soon it’ll show you a folder/file tree and you can hover your cursor over each block (i.e. a folder). There you can find more details. In this case, I clicked “System” folder to continue.
Step 3: The file breakdown below indicates that some Library and iOS Support files are the culprits.
The interesting part is that the System file size shown in CleanMyMac is much smaller than the size shown in System Information. This puzzles me and makes me believe that Apple definitely has counted some other files (not real system files) in the System category.
What are they? I have no clue, honestly. But as reported by other Mac users who experienced the same issue, they said Apple also considers app caches and iTunes backup files as System files.
Out of curiosity, I ran CleanMyMac again for a quick scan. That app found 13.92 GB in iTunes Junk. Further review revealed that the junk files are old iOS device backups, software updates, broken downloads, etc.
But even after adding this amount to the original system files returned by CleanMyMac X, the total size is still a bit less than what’s returned in System Information.
If cleaning the System Storage is still not enough to bring your Mac available disk space to a normal level (i.e. 20% or more), see below.
What Else Can I Do to Reclaim More Disk Space?
There are tons of ways out there. Here are a few of my favorites that should help you get back a decent amount of space quickly.
1. Sort all files by size and delete old large files.
Open Finder, go to Recents and look at the Size column. Click on it to sort all recent files by file size (from large to small). You’ll have a clear overview of what items are eating up a large amount of space, e.g. From 1 GB to 10 GB, and from 100 MB to 1 GB.
On my MacBook Pro, I found a few large videos that could be transferred to an external drive.
Note: If the Size column doesn’t show up, click on the Settings icon and select Arrange By > Size.
2. Remove duplicate files.
Don’t forget those duplicates and similar files! They can stack up without you being aware of it. Finding them is sometimes time-consuming. That’s what Gemini 2 is designed for. Simply select a few frequently used folders (e.g. Documents, Downloads, etc.) in the main zone of Gemini.
It then scans them and returns all the duplicate files that might be worth removing. Of course, it’s always a good practice to review them before doing so. You can also read more from our detailed Gemini review here.
Wrapping It Up
Ever since Apple introduced the Optimized Storage feature, Mac users got the option of saving space by storing content in the cloud. Apple also has several new tools that make it easy to find and remove unneeded files.
That bar under the Storage tab is beautiful. It does allow you to get a quick overview of what’s taking up the most space on our hard drive. However, it still lacks insights into the “System” category as it’s greyed out.
Hopefully, the guides above have helped you figure out the reasons you’ve got so much “System” data, and most importantly you’ve reclaimed some disk space — especially for new MacBooks pre-installed with flash storage — every gigabyte is precious!
Do you have an older Mac with a regular HDD? Learn how to make sure deleted files cannot be recovered by securely wiping the free space on the drive.
When you delete files on a regular hard drive on your Mac (not an SSD), the files remain on the drive. But they’re no longer accessible by your Mac.
However, anyone who gets a hold of your Mac, and who has intermediate computer skills, might be able to recover deleted files from your drive. Unless you delete them securely first.
If you didn’t already securely delete your files, it’s not too late. If you have a regular spinning hard drive (HDD) in your Mac, you can securely wipe the free space on your Mac, preventing recovery of any files that were not securely deleted. If your Mac has an SSD, you do not need to securely wipe the free space and you shouldn’t.
Today we’ll discuss what happened to the Secure Erase Free Space feature in Disk Utility on your Mac and how to securely wipe the free space on your Mac’s HDD without that feature.
What Happened to Secure Erase Free Space in macOS?
The Secure Erase Free Space feature in Disk Utility on your Mac added a layer of privacy and security to file deletion. The feature allowed you to overwrite the free space on a drive to prevent deleted files from being recovered.
Modern versions of macOS, and later versions of OS X, like El Capitan, don’t include the Secure Erase Free Space feature in Disk Utility. Because most Macs now come with Solid State Drives (SSDs) instead of regular hard disks, Apple feels there is no need for the feature. When you erase files normally on an SSD, it’s difficult to recover that data.
Apple explained that you don’t need to securely erase your Mac’s SSD in their online knowledgebase:
With an SSD drive, Secure Erase and Erasing Free Space are not available in Disk Utility. These options are not needed for an SSD drive because a standard erase makes it difficult to recover data from an SSD.Use FileVault to Keep Your Data Safe
Whether you have an SSD or an HDD, you should use FileVault to protect your data. FileVault encrypts your whole drive so all your files are protected. You need a password to access anything on the drive. Without it, your data remains encrypted and safe from unauthorized access.
Securely Wipe the Free Space on Your Mac Using the Command Line
Before wiping the free space on your Mac using the command line, back up your data.
Once you’ve backed up your data, open the Terminal app from the Applications > Utilities folder.
Then, type the following command at the prompt and press Enter.
Make sure you include “freespace” in the command. This indicates you are only erasing the free space on the drive and not the entire drive.
The number “4” indicates the wipe level performed on the drive’s free space. You can use “4” for the wipe level, or select a different option from the following list:
- 0 – Single-pass zero-fill erase.
- 1 – Single-pass random-fill erase.
- 2 – US DoD 7-pass secure erase.
- 3 – Gutmann algorithm 35-pass secure erase.
- 4 – US DoE algorithm 3-pass secure erase.
The more passes you do when wiping the free space, the longer the process takes.
Replace “Macintosh HD” with the name of the volume you want to wipe the free space on. If the name of the volume contains a space, type a backslash in front of the space, like we did in our command. Make sure you include “/Volumes/” before the name of the volume.
When the wiping process finishes, you’ll see a message and you’re returned to the command prompt.
Securely Wipe the Free Space on Your Mac Using CCleaner
CCleaner for Mac has fewer tools available than CCleaner for Windows. But you can use it to securely wipe the free space on an HDD using the free version of CCleaner. You can pay for the Pro version, but it’s not necessary.
Download and install CCleaner. When you open the program, click Tools on the left pane. Then, click Erase Free Space in the middle pane.
Select a volume you want to erase the free space on. Free vst eq plugins download. If you select an SSD, a message displays in the Details box saying Erase Free Space is not available for SSDs.
Once you select a regular HDD, choose one of the following options from the Security drop-down list.
- Zero Out
- 7-Pass Erase
- 35-Pass Erase
Then, click Erase Free Space.
CCleaner warns you that the process may take several hours to complete.
To start erasing the free space on the selected drive, click Yes. If you’ve changed your mind, click No.
If you clicked Yes, enter your password if prompted.
The wiping process begins and the progress displays in the Details box.
Prevent Private Data from Being Recovered
Apple devices, including Macs, are known for lasting a long time. So, if you still have an older Mac with a regular HDD, use one of these methods to ensure your sensitive deleted files can’t be recovered.
