I noticed after my update to MAC OS 12 Monterey that my System Data Folder swelled to an incredible 320 GB, which is 1/3 of the FULL HD. Before the update (was running BIG Sur), the Folder was called Other and was only about 40-50 GB. Any suggestions? It eats disk space unnecessarily. Now also the backups etc are huge. Would appreciate any input. Best, Dino

It turned out to have nothing to do with the system for me. Fortnite was hiding its content in the system folder. I went into Terminal and drilled down. I started with
du -hcd2 /System/Volumes 2> /dev/null
which looks in the given folder (/System/Volumes) and lists all the folders under it and the folders those contain, and the amount of data in each. I found the biggest of those and iterated.
du -hcd2 /System/Volumes/Data/Users 2> /dev/null
Until the culprit was revealed. So, I deleted the old, old version of Fortnite that runs on Apple. Ironically, this is one of our kids' macbooks, and they just wanted space to install xcode to get ready for Fortnite Creative 3.0, but I don't think they'll miss 2-year-old Fortnite.
Just to be pedantic, I'll explain the command. 'du' shows how much disk is used. '-' means options, h means use 'human readable' notation (GB, MB, KB), c means print a summary amount and d2 means go two levels deep. That's just so I don't get too much data to navigate. The '2>/dev/null' bit at the end discards error messages.
I hope this helps!
Not even close to being true.
Oh wow, you're advocating ODS and CMM here? I can hardly wait .......
Yes, they are helpful. I guess you're going to spend more money on a new computer when you run out of space.
Old Toad,
Here are my results:
Interesting, so how did you delete the folder in question? Also, the folder I have has Data in the Volumes under the System.
What is +Shift+. command is? Please clarify...
My problem is just like described, and finder, Omnisweep, and CleanMyMac just don't see where the **** is 350+GB of space is being used...
Hi,
Having the same issue on my 2020 MacBook Pro. Any resolution to this issue besides a clean install? That's hardly a great fix for production machines. Too much downtime.
Thanks.
Adding my shared experience here - nothing anywhere this size in my user Library (150Gb), the System/Library (50Gb) or the root Library (5Gb). Hope that the next Monterey update shrinks it again.
671GB here....this is so frustrating. Apple fix this ASAP pls!
Yup there is! I think the most bottom one?
What should I do next?
The [p09 is my previous disk name..i named it that purposely, but without the seven -Data suffix as you're mentioned. My OS is already Monterey btw
Did anyone solve this issue?
Was a solution to this ever identified? I have the same problem. System Data consuming 272 Gb pf 1 TB storage. Can't find instructions on how to reduce this.
I never saw you reply to this thread. I have the same problem. 500GB of system info. How to fix? Why is this happening. Nothing posted seems to work. I have followed all instructions.
It was called "OTHER" before and apple still has not correct that problem
Mine take up 625gb of a 1tb main drive !!!
