HD space missing after 10.13.3 update

I originally had about 9GB of space left on my Macbook Pro 2012. But after the update, I am down to less than 2GB. I used Daisy Disk and I see about 7GB more in "Hidden Space" than was there earlier this week.

Has anyone else experienced similar issues or know how to fix?
 
It's getting worse. I've tried using Onyx which said that my disk needs to be repaired, so I rebooted and used disk utility, but it found nothing to repair.

I reboot into normal mode and after deleting over 5 GB, I have less than 1.5GB left. I have no idea what's going on. I can't even reinstall the OS because there's not enough room. I just look at the available space and it just continues to go down.

Update: So I deleted Xcode, which ballooned up to 10GB somehow. and it had no effect on the hard drive space. Checking System Information, it says I have 70+GB in System. Daisy Disk says the Hidden Space has grown to 33GB.

I'm guessing everything I tried deleting through the trash bin is getting stored in system folder somewhere. ?? I have no clue.

Sounds like a possible snapshot issue. Is your disk drive a SSD?

Try the following terminal command:
Code: 
tmutil listlocalsnapshots /
You can delete those using:
Code: 
sudo tmutil thinLocalSnapshots / 10000000000 4

Be aware that the snapshots have not been transferred to TimeMachine backups.

Thanks for the help. I do have an SSD but I don't use Time Machine and it is disabled. I tried that command in terminal, and it did nothing..

At this point I revert to the command line.
Code: 
df
sudo du -d 1 -x -c -g /
df will show the real space used. The second will display how much is used in each base directory. Add paths to the slash to drill down, such as /Users.

Thanks - So it says the total is 181gb, so there is still about another 55GB unaccounted for that is taking up space. I have a 240GB SSD, with just under 5GB reported free. Drive is formatted in APFS. I just removed another 11GB from my download folder to another drive, deleted in the Trash, and it freed up only 1 GB.

Any other suggestions? Daisy Disk and OmniDiskSweeper can't seem to read from the protected areas of the disk.

I used the -h option on the df command to get the size is gigabytes.

There are some areas that are protected even when using sudo. This accounts for the difference between df and du.

You don't indicated which command returned 181GB.

So the files in the trash folder are leftover from something else I followed to delete all but the zz folders in /var/folders because of another issue I was having, so this problem might be related to that. If I can just free up some space so I can reinstall macOS I think that would solve everything. I'm hoping this is still possible... :/

9GB or 2GB free, either is woefully inadequate.

The /dev/disk1s4 line looks very strange. It says that the size is 1GB but takes up 23% of 223GB, which happens to be 51GB.

Some more commands:
Code: 
cd /private/var/vm
ls -l

I show:
Code: 
-rw------T   1 root  wheel  1073741824 Nov 29 09:21 sleepimage
-rw-------   1 root  wheel  1073741824 Jan 21 18:09 swapfile0

DS
 
Code: 
total 2097152
-rw------T  1 root  wheel  1073741824 Jan 18 20:24 sleepimage

It appears that I don't have a swapfile, and I thought I disabled hibernation. Still though, I wonder why the other 51GB aren't showing? Seems like we're (you're) getting closer to the root of the problem. :)

UPDATE:
So I rebooted and ran disk utility in restore mode and found some errors:

error: apfs_extentref: btn: invalid o_oid (0x6c42)
Snapshot metadata tree is invalid
The volume /dev/rdisk2s1 could not be verified complete
File system check exit code is 0

I looked up some stuff on it, but seems to be related to Time Machine snapshots (which I have disabled and never used) but booted into single user mode and ran some suggested commands to no avail.. :/

Update 2:

After more research it appears to be an intermittent bug with APFS, and that the "space" that is being used up is not by any particular file, but a bug that is reporting that the drive is full. It looks like I'm going to reformat and start fresh. And I think if I choose to format in HFS instead of APFS (to avoid this in the future) , I will have to start a new profile and spend a day reinstalling everything. Awesome. If you come up with anything DS let me know, but there's a bunch of threads on dev.apple about this with only some people having some success at some fixes.

I think you are correct about some bugs. My condolences.

I originally had about 9GB of space left on my Macbook Pro 2012. But after the update, I am down to less than 2GB. I used Daisy Disk and I see about 7GB more in "Hidden Space" than was there earlier this week.

Has anyone else experienced similar issues or know how to fix?

Yes, a lot of people, and it seems that the hidden space is taken by Time Machine's temp backups that APFS just keeps on accumulating (to be exact, up to 80% of your disk space), but deletes only lazily. Even when you turn Time Machine off, this will not immediately purge the already existing snapshots. It will only happen when your applications actually request more disk space.

Speaking of DaisyDisk, you can try the new public beta that we released just now. It shows more detail inside the hidden space, in particular you will see "purgeable space" (and will be able to delete, i.e. purge it on demand) and also "other volumes". This should clear the confusion on APFS:
