Hello Community,



after reading a lot of posts about how to set a wallpaper for the desktop, I still have not found the solution for my problem:



I created a package wich contains a picture.jpg. This package (picture) should be installed to the directory "/Library/Desktop Pictures". After running the policy to install the picture, the result in the logfile sounds: "Installation failed. The installer reported: installer: Error trying to locate volume at /Library/Desktop Pictures".



When I open a terminal at the target client, and look for the directory, I only can find it at "/Volumes/Macintosh HD/System/Library/Desktop Pictures"



If I paste the complete path as a target to install the picture inside, I get the same response in the logfile.



Can anyone help me to solve this problem ?
Thank you very much for answering and stay health!

Hey,



normally it should work with the setup like this one I attached. Did you used Composer and checked the permissions? I'm using this setup currently since 10.12 and it's still working on 10.15. BigSur should also work.
For changing the background via policy I'm using desktoppr

Hi @Cyberghost , thank you for your fast response!
Meanwhile I found out, that modifying the System Directory on MacOS BigSur is no longer possible. I have to create a new directory and have to store the wallpaper picture in that directory.
We use desktoppr to set up the wallpaper, too.
