How can I remove Desktop Pictures from older versions of MacOS?

I have an M1 Mini with only 256GB of storage. I am often not able to install MacOS updates due to space limitations. While reviewing where my space is going using DaisyDisk, I found that I have over half a gigabyte of wallpaper pictures in /System/Library/Desktop Pictures/. There is another quarter of a gigabyte of movies in the Sonoma folder within that directory.


I really, really don't need "iMac Pink.heic", for example, and don't need or want any of the other desktop pictures or movies. I use a plain green background on my desktop which I find makes names more visible.


Here are the command and responses I am trying to use to remove these:


redacted@Macmini Desktop Pictures % pwd

/System/Library/Desktop Pictures

sudo rm "iMac Pink.heic" 

Password:

override rw-r--r-- root/wheel restricted for iMac Pink.heic? Y

rm: iMac Pink.heic: Operation not permitted


How can I circumvent this? There are a number of other files in the Desktop Pictures directory I would like to remove as well.


This is running under Golden Gate 27.0.1.


Edit: Full Disk Access is enabled for Terminal. Adding the "-f" or "-rf" options has no effect. The ls command for this particular file shows:


-rw-r--r--  1 root  25097873 Sep 24 00:10 iMac Pink.heic

That's part of the signed system volume and not removable.

Many users think that going through Library files is the best way to free up space. It's not. If you delete macOS desktop and/or screensaver files, macOS will often just redownload them anyway.


You should aim to have 15-20% of your total internal storage as free space (~30-40 GB as an absolute minimum). If you do not have enough free space on your Mac’s internal storage, then here are some steps to take to safely free up space:

How to free up ‘System Data’ and other st… - Apple Community

 

"System Data" comprises your data, but they are typically hidden files that Spotlight cannot assign to a specific category like Documents or Applications. Examples include Outlook attachments, iOS updates, Cloud storage caches, etc. Starting with macOS 27 Golden Gate, System Data also includes what macOS used to call ‘purgeable’ storage – system caches, Time Machine snapshots and some other data, though the user had no control over the purging. Trying to manually clean out hidden files in System Data is likely to cause more problems than it solves, macOS hides those files for a good reason. Follow the steps in the linked articles above. 

 

On macOS 27, separate ‘purgeable’ space is no longer reported, and instead those data are now considered as used space. They are also now included in System Data, accounting for the apparent increase you (and others) have noticed. You didn't lose space, macOS just categorizes things differently now than on Tahoe.
