How do I delete the Purgeable Space on Mac OS?
Mac Studio, macOS 14.1
Hello,
my problem is similar, 180 gb available but 165 purgeable resulting in 15 free
when trying to install a newer version of Mac OS >> not enough free space.
And deleting large file doesn’t do anything.
i backed up my music library 50 gb. (Trashed it & empty the trash) It just increased both values but free space remain 15.
the purge didn’t change anything
thx for your help.

In the Terminal application, you can run the purge command which forces disk cache to be flushed and emptied. I would reserve this to a time when you have no open documents or running user applications:
sudo purge
Password:
Enter the administrator password. Nothing will echo to the screen. I do not run this very often as the operating system is quite capable of managing itself.
The purgeable space mostly consists of local snapshots of Time Machine, and also caches, sleep images, swap files and other temporary system files.
To DELETE:
i think you need to understand it's not about dopamine but getting a job done: i can't download footage i need to work with, because the frame.io app doesn't recognize that i have 700gb purgeable space and just says i have only 20gb of free space. now you can go on all day long how frame.io didn't code their app correctly but some of us just need a solution to a considerable problem, not an ill informed lesson on how apple will magically do everything and one should just lay back.
I was able to clear my purgeable data successfully. I used Disk Utility>File> New Image and created images based on what size Disk Utility said I had useable on my HD. I had these created to my desktop for easy deletion later on. I ended up having to create 6 different images as after each creation the purgeable data would decrease and open up more space on the hard drive. I got the purgeable data down to 300 MB from 34 GB. I then deleted all the newly created images to trash and emptied the trash.
The last time I read about Time Machine and two disks used for backup, I thought I read that it would alternate the backup between the drives and not write them concurrently with the same backup.
Use Time Machine on your Mac to back up to multiple disks - Apple Support
hi just went thru this issue for a small MacBook needing >16gb to upgrade the OS, with 41gb available and 25gb purgeable, for whatever reason the OS upgrade doesn't trigger a purge. This solution in the Apple dev forum from 'dotster' provides steps to create very large file(s) of random stuff, this ran and sent the disk info bonkers and eventually this suddenly dumped the purgeable space from 25gb to 400mb; deleted the files to fully reclaim the available space and was able to comfortably proceed with the upgrade and the rest of my life with this mac.

I had also done some other stuff before forcing the purge with not much impact - turned off cloud photo sync I didn't need and purged some other cache and cloud files I didn't need which should have freed up several gb but didn't do anything to the available space for some reason. Also turned off auto backup on TM advised somewhere. Following this whole process and OS upgrade, I am left with 48gb available and only 19mb purgeable.
If deleting Time Machine local snapshots didn't help you reclaim much free space, try the method below.
A more efficient way to delete purgeable space on Mac is by making a file that grows until the disk is full and then deleting the file. It's worth mentioning that previous attempts to create an empty file and then duplicate the file until it uses up your Mac's free space to force your operating system to clear purgeable space to store the file no longer works with APFS.

Another possible way to regain space on a boot drive is to remove all but the latest local snapshot with Disk Utility:
I don't know if the Terminal purge command removes them but you can try and check it out with Disk Utility. If not the use DU to remove all by the latest.
Although purgeable space is reported in various places, the system will quietly & automatically use purgeable space as it needs it. Also, a reboot usually frees up purgeable space, at least on your system drive.
The purge command resets disk cache the same as a reboot would do. I wouldn't spend any more mental time on wondering what Disk Utility is reporting and just let macOS take care of that for you.
I am on my Mac from early morning to late at night and I never care about any purgeable storage, or even run Disk Utility for that matter.
After trying all the suggestions I could find online (none of them worked for me). I sucessfully increased my 'free' space from 14gb to over 100gb by adding volumes on my Macintosh HD drive using disk utility. I would fill these volumes by copying large folders (roughly 80gb) from elsewhere on my mac and then delete remove/delete the volume. Every time I did this my free space increased.
As many others suggest your mac keeps files in this available space for other purposes (I think in my case it was for Google Drive but Im not sure). Then when it needs the space it wipes the secretly saved files. When you then delete the volume it leaves that space as 'free' for you.
I couldnt delete the snapshots as others have even though it did list one snapshot in disk utility.
My issue was linked to installing Native Instruments libraries which uses an installer called Native Access which assesses the available space on your mac from the 'free' space that you can see in disk utility.
Lost about 5 valuable hours on this issue. Im frustrated with Native Instruments not apple. I presume Apple is trying to speed up or make more efficient your future actions as opposed to increase profits (as others suggest on forums).
Anyway I really hope this posst can help others save many, many hours!
Thanks
I am also having grief with purgeable space on my MacBook Pro. I am running Sonoma 14.6.1.
I have run sudo purge from a terminal and no relief. I have rebooted and shutdown an restarted multiple times.
I know that the purgeable space is some video files that I have edited and copied back to my NAS the moved them to trash and emptied the trash. I feel that when I empty the trash the filed should be deleted and the space recovered.
I even tried running first aid in the disk utility and still the purgeable space remains.

The purge Utility has absolutely nothing to do with purgeable space.
macOS should clear any purgeable space if needed. Some poorly written apps will check free space instead of asking for storage space and fail because of the way macOS manages it.
Another possible area to recover storage space is thru the local snapshots created by Time Machine (that is if you use Time Machine).
The deletions are done with Disk Utility.
