It is a MacBook Professional with Apple M2 Professional, 500GB SSD, working Tahoe 26.2.
TL;DR
My System Information is at 350GB. At any time when I delete a big file to unlock some house, as a substitute of free disk house, I get a rise in System Information and I can’t discover something on my disk that’s actually utilizing up all that house.
The Background
A few weeks in the past, Mac OS advised me, that I am working out of disk house. Did not assume a lot of it, went forward and freed about 40GB by deleting previous Downloads which have gathered over time.
Per week or 2 later, my laborious drive was full once more, this time I turned a bit extra suspicious, so I took a more in-depth look. My System Information was at 250GB. I believed that was quite a bit. Did not have time to research additional, so I deleted native snapshots of recordsdata I had in cloud storage. Since these are saved beneath ~/Library/CloudStorage/, I guessed these 60GB the place additionally a part of the 250GB System Information and I ought to have purchased myself a while.
Per week later, I am having the identical concern once more, My drive is simply too full to obtain updates and even end a Time Machine Backup. So I opened up System Settings, and checked out my Storage and naturally System Information was again at 260GB. First I checked if my cloud storage had generated native snapshots, however these are within the very low MB-range, in order that wasn’t it.
To quickly free some house, I moved my hardly ever used Parallels VM to an exterior disk and the weirdest factor occurred: My Paperwork Utilization went down 80GB and on the similar time System Information Utilization went up 70GB.
Proper now System knowledge is at 350GB and I virtually don’t have anything left I can transfer off the disk to free more room.
My Investigation
I attempted to research: My ~/Library/ is about 92GB, about 66GB of that are ~/Library/Software Help/ (about 50GB of these are from the wallpaper-videos, so that’s one disk-hog, however there must be extra). So the place are these different 260GB? I additionally tried some shell instruments to seek out no matter is clogging my disk. df does not appear to work and du tells me, that I’ve used 392GB (in comparison with the 480 System settings declare for use) and I am sure, it counted my 100GB Customers listing twice (as soon as as /Customers/ and as soon as as /System/Volumes/Information/Customers/, so it is really solely 290GB which can be used in my view.
This is the (abbreviated) output of du:
$ sudo du -h -d4 / | kind -h
[...]
27G /System/Volumes/Preboot
41G /Functions
41G /System/Volumes/Information/Functions
62G /Customers/xxx/Library/Software Help
82G /Customers/xxx/Library
105G /System/Volumes/Information/Customers
105G /Customers
105G /Customers/xxx
177G /System/Volumes/Information
204G /System/Volumes
217G /System
392G /
You possibly can clearly see, how the Customers listing is counted twice, how there’s actually nothing substantial bigger than 25GB.
Find out how to repair?
So, how am I going to repair this concern?
What’s the concern anyway?
Is du proper and my disk is not full in any respect? Then why does Mac OS assume in any other case? Or is Mac OS proper? Then the place is that lacking disk house? There are fairly a couple of folders the place du tells me “Operation not permitted” which I discover unusual as a result of I used sudo, however I suppose that could possibly be commonplace OSX behaviour and even when it isn’t it is most likely past the scope of this query, however perhaps these lacking 200GB are hidden someplace there, so how can I discover them?
