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.
