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.

So one more question about how it works on mac, so basically if I delete the file in extension the extension will disappear and that is equal to uninstall in mac right? – SpaceWalker Dec 9 '14 at 0:33. Feb 13, 2017 I'm trying to reduce the size of a PDF without the sharp reduction in quality you get by using Preview's size reduction filter. I found instructions for using custom quartz filters online, but they all direct me to install the file in System/Library/Filters. I've gotten into my Library folder. MacOS Sierra system is using over 200 GB of storage space on my 250 GB hard drive. I've removed Time Machine backups to no avail. How do I free up space? My current usable space being less than 50 GB is getting quite problematic. Edit: The culprit has been found. Imagemagick is. The above is called a 'Spotlight Search' and is the easiest way to find anything on a Mac. Install homebrew. Then, if you want to install OpenCV on a Mac, install a package manager such as homebrew which is a matter of copying and pasting a single line from the homebrew website into your Terminal. I will not show the line here in case it ever.

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 How to download brushes for gimp on mac. window… and the “System” row is greyed out.

Why does my Mac system require so much space?

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.

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.

https://wknwsm.weebly.com/blog/how-to-remove-apps-from-mac-sierra. 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. Why cant i download instagram on my mac. 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

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!
