How to get back or remove purgeable space.

Hi,

1. Is there a way(simple) to get back my disk space captured by this so called "purgeable space", or is there an app which can help do the same.

2. Does apps such as clean my mac/omnidisk sweeper help in getting the disk storage back from "purgeable space".

I am usuing macbook pro(mid 2015) 15", OS Sierra.

Subhash.

I just realized I didn't post the link to the article.

Here's the short version: What is 'Other' and 'Purgeable' in About This Mac? - Apple Support

And here's more info on freeing up space on your hard drive which talks about the purgeable section a bit: Free up storage space on your Mac - Apple Support

1. No.
2. No.

That is entirely under the control of the OS, not the user. Purgeable space is disk space not in use but not empty. The OS can recover that space if needed because the disk is too full. It does not mean you have anything in that space that is gone or recoverable.

There is information here on the Purgeable section in the storage display.

If you don't have Optimize storage turned on, it can also be Local Snapshots which are created by Time Machine when your laptop is not connected to the backup drive. They can be purged if space is needed, or when you connect back to the backup drive and the backups are merged into the Time Machine backup.

Thanks Kappy.

Thanks Barney.

The articles commonly cited and recommended by Apple make a claim that doesn't seem to be substantiated by reality. For example yes you can store photos and documents in the cloud but it fails to purge them from the local hard drive. So when you see 'purgeable' space on your disk yes maybe that is true but it in practice does not actually get purged (and there is no way to invoke this manually). So they may as well label the space as 'photos' and/or 'documents' since it is not really usable space. In the end one is just as limited by a 256gb SDD as they were before this feature arrived (e.g. Unable to download or create new files due to a full disk despite having 100gb 'purgeable' space). Somebody please prove me wrong.

Information only, not an answer. iCloud is a syncing system, not an external storage system.

Thanks Eric, you are 100% correct. I've also moved my issue to my own question.

sudo tmutil disablelocal

Regrettably, a suggestion to disable Time Machine local snapshots has recently been posted to this Discussion.

I strongly recommend that you reject that suggestion as inappropriate. Not only is it completely unrelated to the problem you describe, local snapshots are not included in any available space calculations, and are automatically terminated and removed when additional space is required, as are certain other files normally generated by macOS.

John, thanks for the heads up , I've now enabled local snapshots again as it is not an issue for me.

However, there have been several reports in the developer forums of people asking to get rid of the 'Purgeable Space' - how do you do it?

It prevents them form creating large files stating that there is no space available on disk when in some instances the purgable space is 100Gb

Barney-15E provided the applicable Apple Support documents explaining how it works. Local Snapshots are included in its calculations.

It's supposed to be automatic and not something you need to worry about, though there are occasions in which you might want to disable or exclude certain items from "Optimize Storage": How to use pro apps with Optimized Storage - Apple Support.

Apple could probably explain things a little better. The following link may help explain some of the uncertainty regarding Purgeable Space:

https://blog.macsales.com/39247-rocket-yard-guide-what-is-purgeable-space-in-maco s

It directly answers your questions (edited for the sake of brevity):

Can I Delete Purgeable Files Myself?

 

Not easily.

 

Can I Prevent a File From Being Marked Purgeable?

 

Not directly.

If you have TimeMachine enabled it might be that local snap shots are the issue.  Generally when the backups are successfully completed, the OS will delete the local snapshots.   I have seen a delay in this which causes the local snapshots to remain.

An option is to disable local snapshots but know that this will delete any TimeMachine local backups created between TM backups.  It not delete any files other than the backups that have not been written to TimeMachine.

The command to disable snapshots is:

* sudo tmutil disablelocal *          and must be run from a terminal session.  It will also prompt for an admin password.

Next you do * sudo tmutil enablelocal * to renable use

Hope it helps !

No fun, I am out of space...Google Drive isn't operable as I have run out of space.

From what I read, purgeable space is only usable when I commensurate amount of space is available using iCloud, something I do not accept.

If Apple is forcing my hand and I have to read forums to address technical issues then Apple is no longer the Apple I loved.
