When you are at the logon screen behind the actual place you log in it has the aqua blue wallpaper. You can change this, and this is what I am going to hopefully change mine to.What is login screen background?

Behind the initial login screen, the background image is blue with some white arcs running through it in a semicircular pattern. It's very pretty -- the first 4,000 times you have to look at it. If you'd like to express your creativity by replacing this background with something groovier and more personal, you can use this technique:
1. Choose an image you'd like to use. Any JPEG or PDF file is fine.
2. From the root of your hard drive, open Library: Desktop Pictures. A list of the standard Apple desktop images appears. Aqua Blue.jpg is the file you want to replace. Drag it out of the folder to a safe place as a backup (or just re**** it).
3. Drag your own graphic into the Desktop Pictures folder. Re**** your file Aqua Blue.jpg. This sleight of hand allows the system to find it during the boot process.
4. Restart the machine, and your new image appears behind your login screen.
sudo screen -m -d bash -c "sleep 120; screencapture /Users/username/Desktop/loginscreen.tiff"
Well thats no good. What if you change your login avatar, or login name!...You'll need to change the picture too!schaef2493 said:I'm willing to bet he just made an image of the reflection in PS and then used that. Optical Illusion.
I think it would be quite difficult.cschreppel said:Yeah, my jaw dropped when I saw the reflection. I'm sure there's a script somewhere that can do it without much difficulty...although, I'd have no idea how to do it
I think you may be talking about two different things. I agree it would be very difficult (if not impossible) for a real-time effect. But punching out an ImageMagick script to generate this login screen automatically for you when your login window changes (like if you add a user or you change your login icon) isn't too hard.Josh said:I think it would be quite difficult.
The reflection would have to be updated whenever you clicked a button, began typing in your password, etc.
It would either have to be a real-time effect, or staticly update upon each action.
That's well beyond a simple image backdrop, and would require some major tinkering to say the least.
This won't repair anything, but it still could give you a new background. Also you could probably set it to the original aqua blue.iTwitch said:I had to try this. I followed the instructions posted by DJ OJ and wound up with a solid blue background. Next I tried reversing the process, still solid blue background. Any ideas?
Edit: I tried clearing the caches with Onyx, repairing premissions and finally Visage Login. Nothing.
Visage. Its free!Login Background: The second tab lets you use any jpeg image as the background image of your login screen. Visage can even select a random image from your collection so that you will see a different background every time you log out!
As I said I tried Visage. It modified /Library/Desktop Pictures as expected but had no effect on restart. On start/restart I get a gray screen with apple and spinning thing followed by a blue screen with box containing progress bar. No background picture. I tried deleting /Library/Preferences/com.apple.loginwindow.plist but that didn't fix it. Any other ideas are welcomed?DJ OJ said:
