Wallpaper Changes

[billystanton29]

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!
