change login background for Mac OS 10.7.4

Thank you Aptery 🙂

Found this site:-

http://macthemes.net/forum/viewtopic.php?pid=853940

Which suggests that the file is in a new location. I'm new to the tool used to extract the files within SArtFile.bin but I did change one called 267.png and this did change the Login Window background, it was garbled but at least it was different!

I can confirm that the 267.png file is the one that need to be edited. Extract the files from SArtFile.bin. Edit the 267.png when saving make sure you don't flatten the image. Re-encode the SArtFile.bin and using the tool from macthemes.net.

Place the SArtFile.bin back in it's original location /System/Library/PrivateFrameworks/CoreUI.framework/Versions/A/Resources/

Reboot and you should see the custom Login Window Background.

I am having trouble finding the tool at macthemes.net

Try here...

Tried... and failed.

The bin file encoded is more than 17 Mb when the original was 9.4Mb that's strange.

The login picture (at the full resolution of my screen 1920x1080) appears scrambled and tiled, with this version of lion is it impossible to have a single full resolution picture?

Sorry to hear that. I must admit I simply changed the 267.png to reflect our Institutes colour and kept the size and resolution the same.

When I first tried it was scrambled until I created a new file (in Photoshop) with a blank background and the coloured layer on top. I saved the file as a .png, keeping the layers, and the image was no longer scrambled. There must be another file which tells this image to be tiled.

I'm happy with what I have so I'll leave that to someone else!

When I expand the files, all I get are PDFs no PNGs. Am I doing something wrong?

I think you are completely wrapped up in your own tiny perspective. Please be aware that there are administrators responsible for thousands and thousands of machines. We're not just talking about "I can't change my login screen" here. It effects many more people than appears to you.

Keep an open mind when you are here, and try to be supportive in your responses. "I'd" appreciate it. 🙂

What did I say that was misleading?

Yep. That solution is working on my machine. I'm somewhat relieved, as I feared they might be reading the background image from the rescue partition. No. That is not a hint, Apple. 😉

It should be noted that the ReadMe for the SArtFileTool has the final conversion step as:

5. ./sartfiletool artfiles SArtFile.bin SArtFile.new.bin

It should be:

5. ./sartfiletool -e artfiles SArtFile.bin SArtFile.new.bin

At least that's the case on my machine...

You did not experience finding PDFs in stead of PNGs?

No, but I did experience finding PDFs and PNGs in the extracted folder. Are you sorting by Kind?
