I have easily been able to make my x86 "About This Mac" window both accurate in real-time i.e. when I change overclock, speeds the CPU speed in the window changes automatically, and also ONLY IN LEOPARD 'cool looking' as a black 'transparent' window.
NO WARRANTY IS IMPLIED OR GIVEN AS TO WHETHER OR NOT THESE STEPS WILL WORK FOR YOU AS THEY HAVE FOR ME.
This is how:
Step 1. To make the "About This Mac" window black but 'transparent', firstly download the files from
Unzip the downloaded file.
Follow instructions (my additional instructions are in italics) included in the downloaded ZIP file to achieve the black 'transparent' window effect:
Instructions for setting "About This Mac" backgrounds.
1. Navigate to System/LibraryCoreServices/Loginwindow.
2. Right click Loginwindow and click Show package contents.
3. Click Contents/Resorces, then drag "MacOSX.tiff" (Grey/Black Apple MacOSX.tif) onto the desktop to keep as a backup copy, and then right click on the original file within the Resources folder and send to trash. You will have to enter your password to do this.
4. Drag the replacement "MacOSX.tiff" image (from Std MacOS X tiff white Writing) back into the folder you deleted the original from. You will have to enter your password again. This will ensure that the 'Mac OS X' logo is in white rather than black and so visible in the transparent black "About This Mac" window.
5. Also within Resources (within the English.lproj [or your language.lproj] folder within the Resources folder), you will see "About this Mac.nib". Back up your existing file by dragging it onto the desktop to keep as a backup copy and replace with the new one in this folder. This will give the "About this Mac" window the transparent look that matches "Quick Look" in Leopard. This will only work in Leopard.
6. Repair Permissions with Disk Utility.
7. You must logout & then Log Back in.
8. Open "About This Mac" and view your new image.
Notes:- A copy of the original items are included in the file if you want to go back to the original at any time.

Many thanks to aquamac for Step 1!
Step 2. Changing "About This Mac" Processor from 2.40 (or whatever your CPU speed is) GHz Unknown to 2.40 (or whatever your CPU speed is) GHz Intel Core2 Quad CPU Q6600 download the file from
and simply run the AboutThisMac installer package. Then click on the Apple and highlight "About This Mac" etc. as usual and you should see in white writing on the 'transparent' black background.....
Processor 3.3 GHz Intel Core2 Quad CPU Q6600
BUT with your own specific Q6600 CPU clock speed.....
If you have any problems with the CPU clock speed being reported incorrectly, enter the Terminal and run the command
sysctl -n machdep.cpu.brand_string
Then contact eddie11c via his entries this forum thread
and report what this command throws up in Terminal...
Many thanks to eddie11c for Step 2!
