From the first time transparent Mac appears on the world of web, about several years ago,
it has brought many interests and discussions among people, including me. I've tried to,
but still cannot resist to collect more of those transparent Mac screens around the net
and share them with you.
You will see seventy more transparent Mac screens shown after the jump. Hope you will
like it.
Tip: Photo of transparent Mac screens shown below aren't likely to be photoshopped.

Even though we have put transparent image as our login pictures, the white square box will still be there. This indicates that there is lack of transparency in displaying our login pictures.
But now, it's not a problem. Mac OS X Hints has put up a really interesting topic about how to enable this transparency. All of the steps are done in Terminal.
In their article, Show User Pictures with Transparency, I can conclude three main steps used in adding transparency to login pictures.
-
dscl . -read /Users/[your username] Picture
This will help you identify which image you're currently using for Desktop picture. As a response, Terminal will return the path of the picture.
Picture: /Library/User Pictures/Animals/Butterfly.tif
Don't forget to copy the path to this file, as you will need it later.
-
sudo dscl . -delete /Users/[your username] JPEGPhoto
As explained inside the article, we will have a JPEG version of the image. This JPEG version is the culprit behind the inability to display alpha transparency. With the command line above, this JPEG version will be removed.
-
sudo dscl . -change /Users/[your username] Picture '/Library/User Pictures/Animals/Butterfly.tif' '/Library/User Pictures/New/Smile.tiff'
The first parameter under the single quote is the path to the current login picture. This is the path that you've copied to clipboard at the 1st step.
The second parameter is the path to new login picture that you want to use. Obviously, use new login picture with some transparencies. You need to provide the full path of it. (Hint: You can use drag and drop to accomplish this task)
As usual, logout for the change to take effect.
I cannot fully guarantee that this trick will not harm your Mac. The only thing I can prove is that this trick didn't harm my Mac. So, you can try it for your own risk.
