Customize OS X's Login Screen with Any Logo You Want

The login screen on your Mac is perfectly functional as it is, but if you want to spice it up a little bit, blogger Jacob Salmela shows you how to customize the login screen with a logo of your choosing.

If you don't want to install a whole program just for a simple tweak it's easy to do manually. All you need is a PNG that's 428 X 248. Then, you'll need to save it as four different files.

Here's instructions:

You need four copies of this file, and they need to be named:

  • apple.png
  • apple@2x.png
  • apple_s1.png
  • apple_s1@2x.png

Once they are named correctly, just drag them into the following path:

/System/Library/PrivateFrameworks/LoginUIKit.framework/Versions/A/Frameworks/LoginUICore.framework/Resources/

and then choose to replace all of them.

That's it, log out, and you should see your new logo. Head over to Salmela's site for a few sample images and instructions for making your own.

First - open Finder -> Go to folder -> /Library/Caches

The second - find file com.apple.desktop.admin.png and replays it with your image ;) filename need be same = com.apple.desktop.admin.png. You also may rename jpg file to png without converting.

Launch the Terminal, you'll see a list of all your messages. From the mail prompt, do

$ mail
? delete *
? q

And that should be it. Make sure do to the q after the delete * command, that saves the changes to disk.

Here’s the command. Just paste this line into your Terminal, and press return.

defaults write com.apple.screencapture disable-shadow -bool true
killall SystemUIServer

To test out your new screenshot settings, just take a quick screenshot by pressing the key combination command-shift-4, followed by the spacebar. You should end up with a beautifully clean window screenshot, free of drop shadows. The best part about this is that your screenshot’s dimensions will now finally match the window’s dimensions, without all that added padding introduced by the drop shadow. Nice, huh?

If you no longer want these cleaned up windows, you can switch back to the normal shadowed screenshots by pasting the following into your Terminal:

defaults write com.apple.screencapture disable-shadow -bool false
killall SystemUIServer

Well done!
