Prettier Than Linen: Change The Login Screen Wallpaper In OS X Mavericks [OS X Tips]

Login Screen Wallpaper Mavericks

The login screen wallpaper in OS X Mavericks is a pretty boring dark gray linen picture, with the Apple logo in the center. Yawn.

Far better to put in your own image, thereby customizing the login screen for your very own purposes, am I right? It’s not too tricky to do so, though it does require replacing some system files and will get rid of the Apple logo image itself.

If you don’t mind replacing that Apple logo with a much larger image, thereby hiding the linen look but losing the Apple logo, then here’s how to do just that.

Find a large image you want to have as your login screen wallpaper, either with a Google image search or an image you took yourself. Next, open this up in Preview and save as a .PNG file, using the Export function. Then, in the Finder, make copies of the file until you have a total of four. Rename them to apple.png, apple_s1.png, (sorry, you need Javascript to see this e-mail address), and (sorry, you need Javascript to see this e-mail address).

Now, go backup the Apple logo for the linen login screen. Hit Command-Shift-G and type or paste the following path into the resulting field:

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

Option-drag the four files there out to a folder on your Desktop, or anywhere else you want to back these files up. This will copy the files to your folder.

Next, drag all of the four files you created with your own image to this /Resources folder, and allow your Mac to replace the files there (you made a backup above, so it’s ok). You’ll probably need to type in your administrator password and login name here.

To see the changes, all you need to do is Log Out of your Mac, either by hitting Command-Shift-Q, or Choosing Log out from the Apple menu.

    Does anybody know what is a good image size to use? my photos are either too small or too big that you can’t see them???

    Was this for OS X Mountain Lion?

    I can’t find the Frameworks folder, and the login screen isn’t linen on Mavericks– it’s solid gray.

    Nope, Mavericks – I did the replace myself and it did take a while for the Finder to refresh and show me those files. Did you use the Go to Folder command, or try and click through the directory structure?

    The image I used above is 1483 X 900, but you should be able to use anything that’s the same size as your screen resolution to good effect.

    Is Finder getting stuck? In other words, is there a little rotating gear icon in the lower right corner of the Finder window? If so, try forcing Finder to quit (Command-Shift-Esc) and then try again.

    i did everything just fine but the image is cropped short and the restart and shutdown links are shown how do I make it full screen so the restart and shutdown links aren’t showing? Also how do I modify Mavericks boot screen?

    Actually this is the right path- /System/Library/PrivateFrameworks/LoginUIKit.framework/Versions/A/Frameworks/LoginUICore.framework/Resources
