Hi All,



We are looking to change our company wallpaper on our Mac's, and in past we have done this by saving the image to a test Mac, and using composer to create a DMG of the folder location.



We then push this folder out to users, and once pushed out, we changed the filename on a restrictions config profile.



The problem we have now, is that we have a mixture of APFS and Mac OS Journaled devices, so the composer route seems to add a bit more complication.



Can anybody advise on a better way of doing this?



Thank you!

You can do this with a configuration profile in the Restrictions payload under "Functionality." Use composer to make a pkg with your picture (/Library/Desktop Pictures/ would be a good place), and then use your custom picture's path in the profile.



The downside is if you just want to make this a default and let the user change it, the "Lock desktop picture" check box state seems to be ignored—at least when i've played around with it.

A small piece of python can be used to set the desktop in a login triggered policy:



#!/usr/bin/python



from AppKit import NSWorkspace, NSScreen

from Foundation import NSURL

from subprocess import call

from os import system

import sys



picture_path = str(sys.argv[4]) # jamf variable for the script

#picture_path = "/Library/Desktop Pictures/Bahamas Aerial.jpg"



file_url = NSURL.fileURLWithPath_(picture_path)

options = {}

ws = NSWorkspace.sharedWorkspace()

for screen in NSScreen.screens():

    (result, error) = ws.setDesktopImageURL_forScreen_options_error_(file_url, screen, options, None)

I have a first-run policy that triggers when a user logs in for the first time that executes the following command, the picture is dropped in a folder by an enrollment completed policy:



currentUser=$(/bin/ls -l /dev/console | /usr/bin/awk '{print $3}'); sudo -u $currentUser -H osascript -e 'tell application "Finder" to set desktop picture to POSIX file "/path/to/wallpaper.jpg"'

as far as distribution goes,



you could always host the file on a server..and do the following via jamf with shell or applescript - then set the config profile to the path specified? 



#!/usr/bin/osascript



set UNAME to "username"

set PASSW to "password"



try

    do shell script "mkdir /Library/DirectoryHere/" user name UNAME password PASSW with administrator privileges

end try



try

    do shell script "curl -o /Library/DirectoryHere/WallpaperHere.jpg  http://server.com/wallpapers/Wallpaper.jpg" user name UNAME password PASSW with administrator privileges

end try

Thank you!



This is what I was after, an alternative method of pushing the image out.



Thanks all!
