Wie ändere ich das Hintergrundbild beim Anmeldebildschirm aller User.

Wenn ich auf das Icon gehe, stimmt der Hintergrund wieder.

Ich hatte das bei einem früheren MacOS mal. Weiß aber nicht mehr wie.

Liebe Grüße,
Andi

Was having the same issue, but looked for possible solutions in the web and found these steps that actually fixed it very quickly, even though they were probably meant for a previous version of macOS:
  1. Copy the PNG you want as login window wallpaper to the /Library/Caches folder
  2. Make sure the above mentioned file name is set to "com.apple.desktop.admin.png"
  3. Log Out
The new background should be there by then.
Keep the following in mind:

  • I'm using Macbook Pro (16-inch, 2021) with the latest version of macOS Monterey (12.1) as of today
  • My current screen resolution is 2056x1329 which is the higher scaled resolution available in Display Settings for the built-in Retina XDR display
  • Try to make sure the image has the same dimensions as a standard macOS static lock screen background - you can use the one in "/Library/Caches/Desktop Pictures/<your UID>/lockscreen.png" as an example
  • FileVault has been turned on since the macbook was initialized so that shouldn't be an issue in this case like it was mentioned in previous posts
