How to Customize the Mac OS X Login Screen in Snow Leopard, Tiger, etc

Feb 22, 2007 - 91 Comments


After several hundred times of logging into your Mac you may be tired of looking at the same old login screen. Maybe you’d like to have a customized login screen for your school or employer’s workstations.

Forget the $10 programs that automate the process, we’ll show you how to customize the login screen entirely on your own, for free. It’s not as difficult as you might think, and it’s a fun way to personalize your Mac a bit more. Be sure to check out the screenshot below for an example of the results.

This tutorial details how customize the login screen on Mac OS X Tiger 10.4, Mac OS X Snow Leopard 10.6, Mac OS X Leopard 10.5, and more.

Changing the Login Screen Apple Logo in 10.4 and before

Changing the default Apple logo is quite easy and you can put virtually any 90×90 tif image in it’s place, here’s how to do it through the GUI:

  1. Hit command-shift-G to bring up the “Go to Folder” dialog and paste in the following path exactly:
  2. In this directory you will find a file called applelogo.tif. Make a backup copy of the file ‘applelogo.tif’ by holding down the option key and dragging it to your desktop. this is very important if you want to revert to the default Apple logo
  3. Rename your custom tif logo file to ‘applelogo.tif’ and move it to this same Resources/ folder, you will be asked for the administrator password. Note: it must be 90×90 and a tif file (preferably transparent for best results)
  4. That’s it! Now when you login, your new logo will appear. To revert back to the default Apple logo, follow the same directions and replace the new logo with the original applelogo.tif file that you backed up

Change the Login Screen Apple Logo in 10.5 Leopard

Follow the exact same directions as above, but use this directory instead:
Everything else is the same!

Changing the Login Screen Background Image – 10.4 and before

This is even easier than changing the Apple logo, here’s how to do it:

  1. Hit command-shift-G to bring up the “Go to Folder” dialog and paste the following directory path in:
    /Library/Desktop Pictures/
    (You can also just navigate here on your own through the root of your hard drive)
  2. Find ‘Aqua Blue.jpg’ and rename it to ‘Aqua Blue2.jpg’
  3. Move the JPG file you’d like to be displayed as the login screen’s background image to the Desktop Pictures directory, and rename the file to ‘Aqua Blue.jpg’
  4. Close the folders and log out or reboot, your login screen will now display your new image as the background

This trick works easily because ‘Aqua Blue.jpg’ is the default for the background image, so by placing any JPG file as the same name in the Desktop Pictures directory, it will be displayed instead. Cool huh?

Change the Login Screen Wallpaper Image in Snow Leopard 10.6

Directions for Snow Leopard 10.6 are the same as Leopard 10.5 directly below…

Change the Login Screen Wallpaper Image in Leopard 10.5

Launch the terminal and issue the following commands:

  • cd /System/Library/CoreServices
  • sudo mv DefaultDesktop.jpg DefaultDesktop_org.jpg
  • sudo cp /path/of/image.jpg DefaultDesktop.jpg

Of course, change /path/of/image.jpg to the path of the image file you want to use. Basically what you’re doing here is moving to a folder, backing up the old “DefaultDesktop.jpg” by renaming it, and then copying in the new image and naming it “DefaultDesktop.jpg” instead. This trick works the same as it did in 10.4, just with a different file name and location to work with.

The screenshow below demonstrates the final effects of these tricks:

If you happened to have misplaced, deleted, or forgot to backup the ‘applelogo.tif’ file, click here for a backup of it.

    I found that the Apple logo, for 10.4 and down, doesn’t have to remain 90×90 pixels. You can go as large as 250×250 pixels. Anything larger than that will be cut off.

  2. Daffou says:

    on Lion (currently Golden Master) the login texture is customizable, you can find it here…

  3. taxi says:

    here is a solution i found …. not sure if it is the best but it seems to work for me , at least i get my login screen back.

    1.Find a friend who uses mac ( Alternatively if u have time machine old back ups i think it will work too)
    2.Copy & paste & replace the following 2 files from his/her mac or form ur time machine backups to yours


    (for those who has DefaultDesktop_org.jpg, just delete that file and replaced with the DefaultDesktop.jpg u copy from ur friend’s mac)

    Again, i’m really not a expert in mac, so i’m not sure if this is the best way to do it,but hope this will help.

  4. taxi says:

    Btw, i think whoever post this tutorial should have remove this post or update this with a warming, since there are so many people end up with problematic situation !

    I would like to know how I could change the Mouse Position on the Login Screen, I find it a bit of a drag bringing down the mouse from the upper left corner of the screen, plus I want to know how to change the cursor speed on the Login Menu as well. Lets say for example for the new Position of where the mouse begins I want it to be at the center of the screen or have it sitting else where thats near the Login Window, to make things easier.

    Thanks :)

    Does anyone know what the hex color code is for the background of where the logo icon is placed? It doesn’t appear that .tif images can be transparent and I would like the background to match.

  20. Phil says:

    So I have this really sweet desktop background right now, and I set my login screen to be the same image b/c that’s how sweet it is. Then I thought “what if I could link them so whenever I change my desktop, it also changes my login screen?!”

    The first thing that came to mind was to create a symlink/alias to the desktop image and drop it in place of the DefaultDesktop.jpg. So I found the plist file where that’s located:

    defaults read

    But I can’t figure out how to access the right node of that object. It’s buried in Background.default.ImageFilePath (I come from javascript land, so I usually access nested objects with dot syntax). Does anyone know how I can retrieve that property in terminal?

    Does that seem like it would work? Or am I oversimplifying a task that is way to complex to be worth the time in the first place?

  25. mccoytest says:

    I have to admit I did not read ALL the comments on changing the login screen for 10.6 but here’s my $.02:
    1) follow the first two instructions
    2) instead of the the third, create a link to a file in your wallpaper directory. It doesn’t have to exist (yet) The following syntax is a good example:
    sudo ln -s /pictures/Wallpapers/myCurrentLoginScreen DefaultDesktop.jpg
    3) that’s all the sudo’s you need; then go to your wallpaper directory and create another soft link from the filename you chose to an existing image, like this:
    ln -s SwirlGreenOnBlack.png CurrentLoginScreen
    4) there is no 4, but now you can change your login screen easily, any time you want, by removing the CurrentLoginScreen link and resetting it to a new image.

    Rebooting will rebuild the file usually

  27. Hotha Dweller says:


    You probably corrupted the plist file

  28. Anon says:

    Had to use a free trial of the $5 software Visage Login to finally get rid of the blue login screen.

  29. Anon says:

    Fixed permissions, and tried Rooty’s second suggestion as well. Still blue = (

  30. RootyMcRooter says:

    this works too apparently

    set new:

    defaults write /Library/Preferences/
    DesktopPicture “/path/to/background/image.jpg”


    defaults write /Library/Preferences/
    DesktopPicture “/System/Library/CoreServices/DefaultDesktop.jpg”

  31. RootyMcRooter says:

    if you are having problems with a blue screen it is likely a permissions issue, make sure you copied it over properly as sudo

    by default users do not have access to anything in /System because it is so easy to mess things up, Apple did this on purpose to avoid problems.

    same thing with the file name, if you can’t rename it, it’s permissions (need admin access, which is why command says sudo)

    you can do all this through the GUI as well, just Get Info on the DefaultDesktop.jpg image and click the lock icon under Sharing & Permissions to unlock it and be able to change the image

  32. Anon says:

    Ditto on the blue screen. Can’t even rename the default background from DefaultDesktop_org.jpg to DefaultDesktop.jpg.

  33. bobbytomorow says:

    thanks now I, like many others, have a plain blue screen as a login image >:(

  34. Bryan says:

    I did the above instructions to change my Login Background for Mac OS X 10.6. Both files DefaultDesktop.jpg and DefaultDesktop_org.jpg changed to the image I wanted. But now my login screen is just a blue screen. What went wrong?

  35. Logan says:

    Go to to download New Login Screen it contains a FREE program to change the background of the login screen in less than 30 seconds!

  36. T Davis says:

    Never mind. Apparently its all the same. It hadn’t occurred to me that upgrading would just set them back to default. I’m embarrassed at how obvious that is.

  37. T Davis says:

    Can we get this updated for Snow Leopard?

  38. E Sheldon says:

    For those with the blue screen: You may have to change the ownership of DefaultDesktop.jpg after copying.

    Important Tip:

    If you create your images on a PC – it will not work. This maybe one of the reasons this trick does not work.

    I created my images on a PC (using Photoshop). I was then able to use Graphic Converter on my Mac and re-save the images. Once I did that it worked.

    1 tiny tip for changing you login screen background.

    The image you are trying to use must not be in a user specific directory i.e. your “Documents” directory etc. Put it somewhere common to all users

  46. pop says:

    This Is only working when I log out. But when I booting I get only blue screen and poor resolution as well. Does any body know, where could be problem?

  47. jesse says:

    Sam you can probably log in through Single user and restore any nib files that you changed. i just messed up my mac by basically erasing my login window, so i couldnt log in at all. luckily i was able to fix it through booting in single user. i think you just have to hold command S as the computer is booting

  48. Sam says:

    i changed the nib files and put a quartz composition on it but now whenever i startup my mac it keeps cycling through a blue screen and a blue screen with a loading icon rotating thing. how do i login and reset it or would i have to reinstall os x. please help!

  49. cardreader says:

    Jessica…Try here: It gives a pretty good explanation.

  50. Jessicakayla says:

    The tutorial didn’t work for me, but i have the Aurora screen. And I did it doing both and neither worked, it just stayed the Aurora. Help?

  51. cardreader says:

    I’m having the same problem as chris davis. Followed the tutorial but now, no matter what I do I get a solid blue login screen. The login box is still there, of course. Any help on this?

  52. Peacekeepr says:

    Is there anyway to change the “box” (for lack of a better word) color? I know you can change both the txt and the background image, but i am interested in changing the color and design of the actual login window box.

  53. cybercarl says:

    In Leopard, does anyone know how, or a site that explains how to change the panel the Apple logo and buttons sit on? I suspect it means altering one of the nib files somewhere, but not sure.

  54. deBaer says:

    Make sure that the applelogo.tif is exactly 72x72dpi, else it will be scaled in the most horrible way. (Under X.5)

  55. Chris Davis says:

    Hey bro’s. Need some help here. I do EVERYTHING that the login background tutorial tells me, but everytime I head over to the login window it stays blue. What up?!?!

    Wait! I made it work. I swapped the resources in the 10.4 directory, instead of the 10.5, it worked straight away. Wierd.

  66. Harlan says:

    @ Seaneee:

    I got the same problem… I deleted caches too, and resaved the nib file, no success. Apple must be caching it somewhere….

  67. Seaneee says:

    So I was able to change the login pic in 10.5, but when I did the icon swap, no dice. Still shows the same old apple logo. Cleaned caches, repaired permissions, restarted. Still same logo. Any ideas?

  68. Rough Rookie says:

    Sorry for lat submittal…I just read NICO’s 12-21-07 tip and it worked like a freakin charm. No problem, no programming, and it worked perfectly the first time out.

    I tried to change the Aurora image at login to a cooler image – Earth…

    I did the following;
    Change the Login Screen Wallpaper Image in Leopard 10.5
    Launch the terminal and issue the following commands:

    cd /System/Library/CoreServices
    sudo mv DefaultDesktop.jpg DefaultDesktop_org.jpg
    sudo cp /path/of/image.jpg DefaultDesktop.jpg

    first of all, what is SUDO MV and CP? I presume it’s move and copy?

    After doing the Command shift G thing and getting the prompt, I still couldn’t modify the art.

    Seems simple…someone please help!

  70. nico says:

    Easier way to change login screen wallpaper with 10.5.1:
    – choose a .jpg image
    – name it DefaultDesktop_org.jpg
    – bring it in the core services folder (System/Library/CoreServices)
    – authentify when system ask for it
    – tip password
    – choose “replace” …and it’s done, without working in Terminal

  71. Jason Huebel says:

    Thanks so much for this set of tips. I upgraded to Leopard this evening and was flabbergasted that Apple would use such a hideous background on the login screen. I mean really, all that purple and the lame star field? Back to the nice, quiet, clean Aqua Blue background…

  72. Jay Monk says:

    i just realized the potential of being in the folder where the logo is in leopard. you can switch out peoples icons so that the close red ball is now green or any other colour. you can switch out the shut down and restart icons. just screw around with people lol. and yes thanks for the tips.

    adurdin that is awesome I much prefer that over replacing the original JPG file

  83. adurdin says:

    Yes, open up and write

    defaults write /Library/Preferences/ DesktopPicture /Users/Shared/Wallpaper-Serenity.jpg

    Change /Users/Shared/Wallpaper-Serenity.jpg with the path to whatever wallpaper you want to use, of course — if you don’t know what the path will be, then just drag the file into the terminal and it’ll write out the path for you.

  84. anon says:

    great tip. i wonder if there is a “more elegant” way to do this without changing the background to “Aqua Blue.jpg.” I’m thinking that there is probably a way to set a file pointing somewhere to “Crazy Reflection.jpg” or whatever your background file might be.

    Either way it doesn’t matter but just thinking aloud.
