Basically, you just need to put an image of your choice into a System folder and rename it. However, Finder will not allow you to do it for security reasons. So follow these steps:

Changing the Login Screen

  • Copy the new image to /System/Library/CoreServices. Let’s call it oldimage.jpg
  • Launch Terminal. Don’t know how? Just type “Terminal” in Spotlight(Cmd+Space)
  • Type in the following commands:
  1. cd /System/Library/CoreServices
  2. sudo mv DefaultDesktop.jpg DefaultDesktop_bkp.jpg
  3. enter your password and press enter, when asked for it. you won’t see any characters while you type it.
  4. sudo mv oldimage.jpg DefaultDesktop.jpg

We also created a backup copy of the default image in case you might want to revert to it in the future.
