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.
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.
Just click the Clean under memory in the Cleanup section to free up ram Mac instantly. Cleanup will take care of RAM usage of installed processes and apps. However, besides being able to clean Mac and free up memory it can offer a lot of other useful functions. Let us describe more ways how to free up ram mac. This method is used through the default Mac app – the Terminal application. Enter the following command to proceed: sudo purge. The next step is to enter a password, asked by your system. This will clear your inactive memory.
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!
When you check the storage on your Mac, you might see a significant percentage of space occupied by something called ‘Other.’ macOS does not go into much detail. You may wonder what is Other storage on Mac, why it eats up so much space, and how can I delete it? Let me help by telling you more about this to free space on your Mac.
How to Check Storage on Mac
- Click on the Apple logo from the top-left and choose About This Mac.
- Click on Storage. Wait for a few seconds.
- Take the mouse pointer to colored sections. You will see how much space is occupied by different categories like Apps, Photos, System, Trash, Other, etc.
What is Other on Mac Storage?
Just like the ‘Other’ on iPhone and iPad, it is home to several files, cached data, and more. This section houses a mix of junk and important files.
In the simplest of terms, the “Other” category is a combination of files that are not recognized as one of the other file types. Here are some examples:-
- Common documents and file types, including PDF, doc, PSD, etc.
- Any type of archives and disk images, including zips, dmg, iso, tar, etc.
- Files in the system folders of macOS, including temporary files, swap, voices, etc.
- Application Support files, iCloud files, Screensavers, etc.
- Cache items, including browser cache and locally stored message media files.
- Fonts, app accessories, application plugins, and app extensions.
- Various file and file types not recognized by Spotlight, for example, a virtual machine hard drive, Windows Boot Camp partitions, etc.
How to Delete Other on Mac Storage
Delete Cache Files on Mac
In typical situations, you do not need to worry much about cache. macOS handles them smartly. But if you are too low on storage or believe in having the cache of unused/uninstalled apps, here is how to delete them.
Note: Caches are there to make your Mac experience better and faster. Make sure you remove only the unnecessary ones.
- From Finder, click on Go.
- Press the option key. You will see a new option for the Library. Click on it.
- Click on Caches.
- Right-click on unnecessary app/service folders and choose Move to Trash.
- Right-click on the Trash icon and choose Empty Trash.
Note + Tip: With regular use, macOS will recreate these caches. If you do not understand what to delete, go back and copy the entire Caches folder to desktop (for backup). Next, open the Caches folder, press Command + A, right-click, and then Move to Trash. Finally, empty the Trash. See if everything works properly or not. In case not, copy the contents of the backup Caches folder from desktop inside the actual Caches folder.
Clearing browser cache and website files for Safari also reduce the Other storage.
Clear Temporary Files Located in Other Storage on Mac
- From Finder, click on Go.
- Press the option key.
- Click on Library.
- Click on Application Support.
- Delete files from here that you do not need. For example, old app folders that you do not need or have.
Remove Safari Extensions on Mac
At times, we install a browser extension for a purpose, and then do not reuse them or simply forget that it exists. The extension continues to occupy space (shown differently than the application itself. It is thus categorized under Other)
To remove an extension:
- Safari: Open Safari → Click on Safari from top left → Preferences → Extensions → Click on an extension → Choose Uninstall.
- Chrome: Open Chrome → Extensions icon (puzzle icon next to account picture) → Manage Extensions → Remove those you do not use.
Remove Old Downloads
Downloads are usually saved in the Downloads folder (unless you changed them). We often download .dmg files, large packages, videos, zip files, and leave them there. For example, many people do not delete the .dmg file even after app installation. Same for zip files.
- Open Finder and click on Downloads from the left sidebar.
- Click on the word ‘Size’ to arrange the items by size. This will help you locate the large files quickly.
- To delete, right-click on the file and choose Move to Trash. You may also select the files(s) and press Command + Delete.
Tip: Use Spotlight Search to search for big file types like – .dmg, .zip, .mp4, .mkv, .avi, etc. Then click on Show all in Finder… from the lower-left of the Spotlight Search screen. Next, you can delete them easily.
Delete Unnecessary iPhone and iPad Backups
iOS and iPadOS device backups might run into various gigabytes. If you have several archived backups or unnecessary backups of old devices, make sure to delete them.
- Click on the Apple logo and choose About This Mac.
- Click on Storage → Manage.
- Select iOS Files from the sidebar.
- Click on the files and choose Delete.
Note: If you accidentally delete a backup, go ahead and easily create a new one now.
Delete Unused Applications
Applications, when combined with their data, folders, etc. might be vast and occupy significant space. If you have several apps that are sitting idle, go ahead and delete them. Additionally, remove macOS install files, if any.
- Click on the Apple logo from the top-left and choose About This Mac.
- Click on Storage. Next, click on Manage.
- Select Applications from the sidebar.
- Click on an unnecessary one and then click on Delete.
Note: You may also use apps like App Cleaner for perfect uninstallation.
