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]‘
$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]”
$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/
- Replace ‘applelogo.tif’ with this one:
title="Black Apple Logo">‘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.
