I just want to send a summary post since it seems this thread is getting some attention again.
My original answer will give you contacts on when these “storage folder started.
User medwds was helpful in explains what an .ipdf is. If you want to see the other languages just command click (right click) the file and select “Show Package Contents."
User damimic23 was very helpful by providing the boiler-plate language from the explanation PDF.
I only want to add a bit about the two different possibilities since it seems many are misunderstanding this.
The two different outcomes:
- "These configuration files were modified or customized by you, by another user, or by an app. The modifications may be incompatible with the recent macOS upgrade. The modified files are in the Configuration folder, organized in subfolders named for their original locations."
- "Configuration files with the suffix "system_default" were edited or customized, but the changes were allowed to remain installed. The system_default version of the file is provided to demonstrate what the Apple supplied version of this file would look like. It is recommended that you compare the two and evaluate whether you wish to integrate any changes Apple may have made to the default version."
So, if your configuration files in the Relocated Items Folder end with .system_default you are only looking at an example doc. If you delete the folder or these items all you are deleting is an example Apple provided so you can compare what custom configurations went into place.
To compare you will need to access the private folder of your macOS. To access this folder follow these steps:
- Open a Finder window
- Select “Go” from the menu at the top of your screen
- Select “Go to Folder…” from the list
- Type “/private/etc” without the quotation marks then select Go.
Finder will open the private folder etc which contain the documents macOS is actually referencing while running operations.
In my case this is the comparison revealed:
- I am missing the listing "_appstore:*:33:33::0:0:Mac App Store Service:/var/db/appstore:/usr/bin/false"
- I have an additional "_nsurlstoraged:*:243:243::0:0:NSURLStorage Daemon:/var/empty:/usr/bin/false"
- I am missing everything below the wwwproxy... one.
I have no idea what this means for my system so I am contacting Apple Support. If anyone knows, feel free to reply letting me know.
I hope this helps.
