How to change Login Screen Background in Mac OS X Leopard / Snow Leopard
This guide will teach you how you can change the login screen background from the default 'Aurora' to a custom one. <b>(NOTE: All commands to be entered in terminal are given in italics)</b>
1. First of all, make sure that the file you want to use as the background is in .jpg format.
2. Open Terminal and type <i>cd /System/Library/CoreServices</i>, press return.
3. Now we will make a backup of your default login background. For this, type <i>sudo mv DefaultDesktop.jpg DefaultDesktop_org.jpg</i> and press return again. Enter your password if prompted and press return once more.
4. Now type <i>sudo cp /path/of/image.jpg DefaultDesktop.jpg</i> where '/path/of/' will be replaced the directory where your image is located and 'image.jpg' replaced by your file. If you don't know which directory is it in, right click the image and select 'Get info' for the information.
After this, your login screen should now be changed!
