Tweaking Mac Login Window
In my previous articles, I've touched on three interesting login window tweaks, which are:
Applying these three killer tricks, I am sure that your Mac can stand out from the crowd since its booting up. Before throwing you with new trick on login window: changing Apple logo, let me review a bit on the past three tweaks.
Use Transparent Login Picture
By applying this tweak, you will be able to use PNG image (with its beautiful transparency) as your login icon, replacing that old JPEG icon (with its ugly-looking white-box boundary). Only several Terminal commands need to be executed here, but it's quite tedious, so always be careful.
Here are the steps:
-
dscl . -read /Users/[your username] Picture
Return Path → Picture: [current path] - sudo dscl . -delete /Users/[your username] JPEGPhoto
- sudo dscl . -change /Users/[your username] Picture '[current path]' '[new path]'
Example
$dscl . -read /Users/Wendy Picture Picture: /Users/blacky/Desktop/Nest.tif $sudo dscl . -delete /Users/Wendy JPEGPhoto $sudo dscl . -change /Users/Wendy Picture '/Users/blacky/Desktop/Nest.tif' '/Users/blacky/Desktop/smiley.tif'
Add Welcome Message
With this tweak, you can show a welcome message on add your Mac login window. Perhaps, if you always forget your password, you can also put your it as welcome message (but it's not recommended). Only one line of code is required to be executed:
sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText "[msg]"
Example
$sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText "Hello, I am a Mac!"
Change Login Background
This is an old trick, but some people might find it difficult to dig up this tweak from piles of archives, so I decide to bring it up again. With three simple steps, you will be able to change your login window background, i.e. replacing the original Vortex background (if you're using Leopard, of course).
- Open Finder and Hit Command-Shift-G
- Enter Path: '/System/Library/CoreServices/'
- Replace 'DefaultDesktop.jpg' with New JPEG Image
Change Apple Logo
And for the last touch, let's change our big silver Apple to shiny-black Apple.
- Open Finder and Choose Go → Go to Folder… (Command-Shift-G)
- Enter Path: /System/Library/CoreServices/SecurityAgentPlugins/loginwindow.bundle/
Contents/Resources/ - Replace 'applelogo.tif' with this one: 'applelogo.tif'
It's a bit tricky to replace with new image as it involves system file. At first, you need to delete the old file. And after that, you can drag in new file.
Now you can go to your login window and see the changes. I am unable to provide your with screenshots here, because I have found no way to capture screen of my login window. Perhaps, you can suggest me a way to capture my login window, I'd be very happy to know about it.

How do you "Replace" the desktop image with the new one? Do I delete the original file and then put the new one I want in?
Alberto Ravasio
"Perhaps, you can suggest me a way to capture my login window, I'd be very happy to know about it." If you have two Macs you can enable "Screen sharing" on the target and connect to the target Mac with the other one. You can capture whatever screen you need with the usual combination of key Command-Shift-4 or Command-Shift-4-Spacebar.
Andrea
Or you could just use the old fashioned way: a photocamera ;)
Wendy
@Rob
Yes, you should replace the old with new one. But beforehand, please backup the original file first, in case you want to revert back.
@Alberto
Thanks for your suggestion, I will try out this one.
@Andrea
With my current photography skill and 'economic' camera, I doubt I can produce a fine photo compared to take screenshot :-)
Rob
Thanks:)

FYI, this will not work on Mobile, or "external" accounts. We use Active Directory-bound Macs. It seems you can't make this edit unless it's a local account. There may be a way around that, but I have not yet discovered it. SB

Visage Login does all this but the trasperancy but you can probably just save a trasnsperant one. Google it.
Wendy
I've asked uncle Google. Indeed, there is an application to do all of these login window tweak called Visage Login. But, you will need to spend extra $4.95 for this app.
Anyway, saving a transparent icon will not give transparent login icon. Instead, it will give you a white box as background.

Change apple logo I forgot to delete it first. I just replace it and it doesn't work what should I do? Thank for you help Phoomphet
Wendy
Phoomphet, you should double-check it. As far as I know, we can't replace system file, we can only delete the original first and put in new one. Most probably is that your "applelogo.tiff" hasn't been changed, i.e. it's still the original version.
Phoomphet
I don't know. I can replace it and it doesn't work. After that I was delete it (did't put the new one in Resources) Nothing happen!!!
Alex
What does "Return Path" mean? I mean, after I writing "dscl . -read /Users/[your username] Picture" on Terminal, what keys exactly should I press? (I know that after steps 2 and 4 I'm supposed to press "Return", to execute the command, but I'm unsure about number 1..) thanks for the help! great post!
Wendy
Return Path is what you will get after executing that line of command (i.e. dscl … line); it gives you the path to your current login icon. Hope this helps you.
Alex
Oh ok, got it! Looks great now, thanks Wendy =]

Its not accepting the exclamation mark with the quotes for me. (!") .This is what I get after I hit return. -bash: !": event not found

Help! I cannot change the apple on the login screen. No matter what I seem to do, when I log out, it doesn't change. I first went to the correct folder and dragged the new apple in, it asked me to authenticate the replacement, which I did. Everything looked fine, but when I logged out; No Change. I read your comments and changed the apple back to what it was before, and dragged that into the trash, and added the black apple. Still no change. What to do?
Mouse
Aww, I can't get the changing background log in thing to work. I'm using a Macbook Pro, any advice?

Honestly, I've always been more of a fan of just putting the monitor to sleep than screen savers. Sure they look pretty awesome, but if you're sitting at your computer, are you really doing so with the screen saver on?Good luck for the dates. It has been some times since we last heard about the next tour. I hope they can run it accordingly now.WokMMXhLxotW7SSU

Howdy this is somewhat of off topic but I was wanting to know if blogs use WYSIWYG editors or if you have to manually code with HTML. I'm starting a blog soon but have no coding knowledge so I wanted to get guidance from someone with experience. Any help would be enormously appreciated!
