What is System/Volumes/Preboot and is it safe to delete? This file(or Volume) has taken nearly 20GB of the space. And with all these "System files" it has taken too much space on my computer. Can anyone give me a solid answer to whether it can be deleted, or at least reduce it size?
Kind regards,
MacBook Pro 13″
lol I've got 18.8gb on just the same folders. Multiple copies of OS + OS Clone. My guess is that Apple is taking up as much space as possible to push you to buy a new (larger capacity) device. iOS 17 case in point.
Can't tell me that all this is necessary. It's either - bad coding or bad design or bad conduct.

From the size of this and the other system partition you are complaining about, it appears that you may have attempted to install MacOS, and the install failed without completing.
If the install completes correctly, those files are removed when complete, and only very modest sized items (or none) remain in those system directories.
I suppose it is also possible you have put off installing an update or upgrade that 'Software Update' has downloaded automatically for you, in anticipation of your saying, yes, update now.
Hey, Thanks for the reply. I have just updated it to the latest Ventura 13.5.1 but it still exists. Please let me know if you have any ideas.
Thanks
I have the same problem.
An older Etrecheck Pro report shows my Preboot size was 518mb Monterey) and in Ventura the Preboot size is 2,67. GB!!
Maybe that’s why the report gives an ‘excellent’ result (Monterey) and now (Ventura) it ranges from below average to good. (Which isn’t so good for an SSD actually)
Anyone has any insight what gives the difference? (See screenshot) (left is Ventura and right Monterey)
what version of MacOS is this?
This article suggests for macOS 11 Big Sur and later, that Volume is typically under 350 Mega Bytes.
for older macOS that volume is typically 40-50 Mega Bytes

Another reader suggested it may contain the stuff needed BEFORE you can open the Encrypted main Volume.
It's NEVER a good idea to delete anything you didn't create yourself, install yourself or download yourself.
If you didn't create it .. NO, don't delete it.
kaz-k has additional information in your duplicate post.
Have you applied all available software updates?
Yes, I believe I have. (There's nothing showing up in system settings etc)
Just to add, deep within the subfolder of Preboot (3 subfolder in), there are two large files called "os.dmg" and "os.clone.dmg"
It's Ventura 13.5.1
I will have a read at what you sent.
Thanks!
If you still have "install MacOS...' file inside your /Applications folder, try deleting that if no longer needed, and see if the sizes of things normalize.
