System Storage Taking Up Way Too Much Space in macOS Sierra

I cannot find the comment on how to delete the hidden Adobe cache file. Will you please tell me where to find it?

My ios system uses 342.97 GB and is growing. I use adobe photoshop and premier video editing so I may have lots of adobe cache files hidden.

Thank you!

P.S. I'm in Oregon too 🙂

Tried out the solution by HevvyD and it worked. Purgeable space is almost nothing and System Files take up only around 30GB.

There are at least two previous posts regarding the same "issue" (if in fact it is one!), but I'm not sure anyone has got to the bottom of it yet.

Why does the system use 150 GB of storage?

Is it normal that "system" takes up 36 gb of storage? What does is contain? Can it be decreased?

From my own experience I've found out that "iTunes" (yes, I seem to have that showing in the left side) only reports size for Apps and Podcasts - my Music which is nearly 70Gb looks as though it's reported under "System" (as you have found) which is currently at 83Gb - can't confirm because as you state it's greyed out, but all the other items on the left are far less in size so "System" seems the only place the machine has found to report my music content.

Furthermore, if I use Finder and add my actual Music size (70Gb) to Macintosh HD System and Library (8Gb + 5Gb) it gives 83Gb (what the greyed out "System" is reporting).

So I've basically given up trying to understand why it's reporting in the way it is - the concern previously was of a bloated System file section, but that doesn't seem to be the case (and Finder proves that), so may be it will all get sorted in a future update!

Do a Get Info on the System > Library.

Next download OmniDiskSweeper. Run on your Macintosh HD.

I received different results with all three:

About this Mac > Storage 19.37 GB

Get Info on System > Library 8.08 GB

OmnidiskSweeper System > Library 5.3 GB

This suggests to me that Storage results is way off.

You need to report it to Apple Feedback so it can be logged and put in the queue to be fixed.

Same here! I have a separate iTunes tab and it says 0 KB, but with iTunes open it says I have around 32 MB of music files saved... Reallyyyyy wish I could see the breakdown of the System files, I have no idea what's taking up the 70 GB.

I had 114.6 GB of "System" storage, but my computer only had a 256GB SSD, which means that "System" already killed half my computer. Including other work files, the computer was basically full, and the annoying "System is almost full" message keeps popping out. But your trick did work, it cleared about 40 GB, real helpful, thanks!

Same here. I tried watching the TTA vid with David A. Cox but that got me nowhere and I tried to delete some files and got just barely anything done. I am wondering what is causing all this. I would go through Finder and look through the System Files folder although it is grayed out which means I have no access. Ughh, great.

BTW, I tried to use Clean My Mac X but I was only allowed to free up to 500 Megabytes of storage, practically doing nothing. I would use Daisy Disk but you have to pay for that too. I don't want to do the trials because I don't want to get in to that mess of forgetting about the trial ( which has happened to me many of times with other services ) and then having to pay for it, perhaps not working etc. This MacBook I have is from 2015 and it is running Mojave with no problem and runs apps smoothly without much latency so it appearing with this much system storage is crazy to me. So I guess it's not Human Error. And if it's not Human Error then it's Apple's fault. Now I don't want to rant about Apple and the many things that they do wrong but it just seems like it. To add on, they haven't explained why this happens. I even took the problem to a technician from Apple on a phone call and he just said to delete the cache files which did nothing! He suggested that I should delete some of the apps I don't use because there are files that are in the system storage directory. But, here is the catch ... I did that before already and that also did nothing! Maybe because I don't have much downloaded other than 1 game, Google Chrome and Spotify. I tried to disable some apps but that didn't change anything except the fact that it appears it was "removed". Well, I guess that is that and I don't have much to do unless some miracle happens.

I have the same problem, but my "System storage" takes up more space every time I delete something. It's now taking up about 80 GB of storage and thats about 90% of my hard drive, because I have an 128 GB MacBook. I hope there is a solution for this nonsense that is happening with "System storage" taking up most of the space than it should. Look at Windows users, they don't seem to have the problem.

I have a similar problem, my 'System' size is being reported at over 80GB, but i don't know which non-system files are being reported as system ones. I've checked iTunes, its not that, it must be something else. Need to figure out what it is so i can delete it.

Just tried your suggestion but it has made no difference (thanks for trying anyhow), System at 83Gb before, during Safe Mode (after it recalculated) and finally on reboot - still showing 83Gb!

It's worth noting my issue is not incorrect reporting of disk space usage, but rather what it is being recorded against - if it would stop putting music under System and instead show it under iTunes all would be well.

The "System" category appears to be including sandboxed application data, which is stored in ~/Library/Containers/.

I used About This Mac | Storage | Review Files | File Browser to navigate to the folders/files using the most space and found that Docker was growing a file called Docker.qcow2 indefinitely in ~/Library/Containers/. Deleting the file released 30GB from "System" while "Documents" stayed the same size.

Check your Users folder. Even though I had removed users in System Preferences, I discovered there was still folders for past users stored on my mac. I deleted the extra User folders and About This Mac > Storage updated to the correct info.

Here's how I was able to solve this issue:

- Using the Disk Daisy (https://daisydiskapp.com/) trial version allowed me to pinpoint which directory was causing the issue

- In my case, it was the .DocumentRevisions-V100directory which is where Sketch dumps older versions of your documents

- I followed the steps outlined on this post: (https://medium.com/sketch-app-sources/sketch-can-unknowingly-take-way-too-much-h ard-drive-space-here-s-how-to-fix-it-1979e976f2d6#.libhod8u4) and Voila! Solved!

*Keep in mind that even if you aren't a Sketch user, these steps might still help you. Good luck!

I found how to purge half of the system on my mac.

I downloaded OmniDiskSweeper which I accessed and I found that under a folder called fsCached Data, there was about 60GB of cached data. I deleted all of it, which was about 200,000 items and it immediately fixed my system problem, which was originally 87GB. It has dropped down to 27GB now with that.
