+4Hello all,
I am working on deploying the updated company wallpaper. Current attempt is using the script below, but it gives the user a that “Jamf wants access to control Finder...” (screenshot attached). Maybe there is a better way to do this.
#!/bin/sh
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 "/Library/DesktopWallpaper/backgroundDefault.jpg"'
exit 0
+8You need to use a apple script this will avoid any prompts.
This is an example of the one I use.
#!/bin/bash
# $3 is the logged in user - default for most policies.
sudo -u $3 /usr/bin/osascript <<ENDofOSAscript
tell Application "Finder"
set the desktop picture to {"Library:corp:wallpaper:General.jpg"} as alias
end tell
ENDofOSAscript
exit 0
Give Desktoppr a try. I use this to set a default background on our staff users with the option to change it. It works quite well with a launch agent.

For this script, wouldn’t the logged-in user need to be an administrator?

That prompt is macOS TCC for Apple Events (Jamf/osascript trying to automate Finder). If you want to avoid user prompts entirely, I’ve had the best luck using desktoppr (no Finder automation) or Jamf’s wallpaper payload.
If you do stick with AppleScript, you’ll need to pre-approve the automation via a PPPC profile (AppleEvents) so Jamf/osascript is allowed to control Finder.
