@dstranathan below works for us... shows on all displays. osascript -e
'tell application "System Events" to set picture of every desktop to
("/Library/Desktop Pictures/Wallpaper.jpg" as POSIX file as alias)'
@Bernard.Huang hey, we are in the exact same position as you with
display link and the new Macs. did you manage to find a good work around
or a temporary solution?
I had a similar issue when i looked into it our service token had
expired. i had to renew the Service token from Apple's VPP store and
reupload it to our JSS then the apps would populate after this. hope
this helps.
