No Freedom of Disk Space Despite Deletion

I'm having exactly the same issue.

I have generated and deleted huge files, disabled and deleted any local snapshots, rebooted, repaired volumes, deleted from /cores folder etc.

Nothing so far helps.

About to attempt a re-install over the top to see what happens.

Same issue here. I have a suspicion that it's due to Time Machine, as I've seen something similar before when I've been away from my TM destination. The incremental backups that would normally go off to the backup drive get cached locally or something (my memory is a bit hazy on this), until you're able to connect to the TM backup drive again. This means that downloading/installing/deleting all this data is causing significant TM data storage for now. It's possible that completely disabling TM backups *may* help, but I'm really not sure. I *just* had enough space to upgrade both Mac and iPhone, so not going to try and mess with anything further until I get back to my TM server.

Try the following commands:

tmutil listlocalsnapshots /
tmutil listlocalsnapshots /System/Volumes/Data

It seems like those hidden Time Machine snapshots are stored in different locations due to the system partition change.

CAUTION: delete them using

tmutil deletelocalsnapshots <snapshot_date>

Same problem here with space. My Mac got so full that it stopped being able to boot and now I am doing a clean install after wiping the partition.

Does anyone know does Macos 10.15 make a new volume in disk utility?

I'm seem to have Macintosh - Data now underneath Macintosh

Thank you! Freed 56 GB on my 256 GB drive!

Yep, it appears that there's a new readonly partition for the system itself to securely reside in.

xkn thanks so much!! Did the trick. Nice work knowing the suave terminal commands there. Hope this thread helps lots of beta users get around this.

Just to be clear those are ok to delete ?, backup to external harddisk is failling btw

So is it Okay for me to wipe the data HD and still keep all my files. My computer will not load up at all and the only thing that works is recovery mode, but I can’t reinstall a new os because my hard drive is “full”. I really don’t want to loose all my files, but I’m wondering if I’ll be safe by erasing the “data HD”

I had the exact same experiennce. I had around 8 gigs free after downloading the Xcode beta, so I deleted probably around 50 gigs, but I am not regaining any space. I did not gain any space until I deleted the the oldest of the 6 snapshots that tmutil showed. That seemed to coincide with my installtion of Catalina.

Well now that I have space I'm off to install Xcode. I don't think I got back the space from the other files and apps I deleted so I'll have to hope that the snapshot space I regained was enough.

Thanks for the tip xhn.

HI,

the correct syntax to list them all (on any local volume) is

tmutil listlocalsnapshotdates

You don't have to specify any path, this parameters shows every local snapshots that exists anyware on your system.

It is because localsnapshots being created, this is issue happening to everyone.

But on Catalina there is no way to disable localsnapshots creation anymore (it was possible on previous versions)

Use this command to list all of them:

tmutil listlocalsnapshotdates

You can delete some or all of them to free space (your external time machines backups will not be touched)

To delete use:

tmutil deletelocalsnapshots [snapshotdate]

Remember, they will be created again as there is no way to disable them, and you wll be out of space on some hours or days, unless you disable Time Machine backups

You are a genius. That worked.

200+GB freed! Thanks so much.

No, that is the partition with all your data on it.

In addition to Time Machine's problem taking up too much space for local backup, I have also noticed that it is backing up too frequently during working period on Catalina (far more than once per hour.) Why is it backing up as frequently as every few minutes?

tmutil deletelocalsnapshots <snapshot_date>

what is this "<snapshot_date>" i mean what to put there?

Thanks already

Hi,

I have the same problem but it is getting worse. I was stuck with the error of “not enough space” and i tried your solution, but in terminal when i write the code you told, it is saying “tmutil not found”. Right now, i can not see my MacintoshHD partition as well.

I have already tried opening in Safe mode but it is not working either. Is there anyone who stucked like me?

Thank you!!!

I'm getting a error of

Failed to delete all Time Machine local snapshots for volume group containing disk (snapshot name).

Sudo doesn't help. Suggestions?

you type in the full name so e.g. to delete my first one

tmutil deletelocalsnapshots 2020-05-25-204347

repeat for all 6 by changing the numbers
