  • Go to the ‘/Library/Caches/Desktop Pictures’ folder and create a new folder here with the name of your UUID.
  • Here, right-click this new folder and go to ‘Get Info’. Here it is important that your computer has the Write privileges. Allow ‘Read & Write’ to a user, admin, or everyone. 
  1. Here you need to select the current ‘lockscreen.png’ image, in case the image exists in the folder, and rename it to as old-lockscreen.png. 
  2. Now you can find an image to use on your login screen background. Drag-and-drop the image into the open folder.
