Hi

I want to change the login panel in Panther to use the Dept of Defense image that is in the securityagentplugins folder -can anyone help with a quick and simple way to do this?

thanks in advance.

Or give this a shot. http://www.stanford.edu/~keaka/visage.htm
It's not compatible with Panther, though it could help anyway.

I've done this mod for the CAC login window (Screenie).

It's pretty easy to do but it involves modifying system resources. Not just changing the image out, you have to modify .nibs too. I'm sure it could be done with the regular login window, but... I'm not sure exactly which resources control the regular login window since I've only modified the CAC login.

How did you do the screen capture?

demograph68 · Jul 22, 2004, 11:54 AM

It was probably done in ohotoshop.

Is there a good source for CAC setups other than the one by apple?

You can screencap the login window if you have the root user enabled (which you should not). Or at least you could (I'm sure you still can).

deej5871 · Jul 23, 2004, 01:05 AM

Actually taking the screencap involved using a remote login from another computer and the terminal.. I only knew how because of a hint at MacOSXhints but they seem to be down right now.

For the CAC login screen, the stuff you need to change is:
/System/Library/CoreServices/SecurityAgent.app/Contents/Resources/loginpanel.tiff, to the actually image of the DoD logo (or another military one of your choice, which can be found at /System/Library/CoreServices/SecurityAgentPlugins/SCLoginPlugin.bundle/Contents/Resources/).

The .nib file that needs changed is at /System/Library/CoreServices/SecurityAgentPlugins/SCLoginPlugin.bundle/Contents/Resources/English.lproj/login.nib
You need to change the size of the apple logo to the same size as whichever military logo you choose.

That's about it. No photoshop involved..unless of course you want to use it instead of Preview to convert the Dod logo (which is a .gif) to a .tiff.

Wouldn't the Photoshop way be easier though?

The original poster wanted to change the login panel in panther..photoshop couldn't do that.. Unless you're talking about making my screenie, which would be easier, but at the time I took the screen capture I thought it was pretty cool to have the login be DoD..

demograph68 · Jul 23, 2004, 01:59 AM

Sorry to confuse you. I meant your screen pic. d'oh

aristotles · Jul 23, 2004, 12:02 PM

Actually, using Photoshop to scale the logo to the size of the existing Apple supplied logo and backing the original one would be easier considering that you would not risk messing up the nib.

I've done it with the CIA logo.

mikeini · Jul 23, 2004, 09:25 PM

thats so cool .. i saw that at neowin as well.

but any ideas when something that is compatible with panther will come out?

Do you mean Visage? For that I have no idea.. But my mod was done in panther.

Actually, if you only modify the CAC setup there is very little risk, because if you somehow mess them up really bad you can just restart in single-user mode and turn off CAC from there.

how did you do it in panther?

A little like this, as I said earlier...

mikeini · Jul 25, 2004, 12:39 AM

and then how do i "back up" wats there so i can always go back to default ..

thanks.

aristotles · Jul 25, 2004, 03:03 AM

Come on guys, I don't think this user is using a CAC anyways so stop confusing the issue.

If all you want to do is replace the is Apple logo, then quite simply do the following:
1. Create an image with transparency in PS and resize it to 90X90 pixels.
2. Save it as a tiff with a .tif extension.
3. Copy your logo to the desktop.
4. Open up terminal located in /Applications/Utilities/.
5. Type in the following:
cd /System/Library/CoreServices/SecurityAgent.app/Contents/Resources/
sudo cp applelogo.tif applelogo.bak
sudo cp ~/Desktop/younewlogo.tif applelogo.tif
6. Close your terminal and check out the new login screen.

To reverse it:
cd /System/Library/CoreServices/SecurityAgent.app/Contents/Resources/
sudo cp applelogo.bak applelogo.tif

justinp · Jul 25, 2004, 03:04 AM

I think MacOSXHints.com has some info on it. I think turning it on and off is as simple as "sudo cac_setup" and "suco cac_setup -off" or something like that. To get the department logos you have to modify the login panel as mentioned.

mikeini · Jul 25, 2004, 05:23 AM

thanks aristotle.

when i get some time tomorrow (after work) iw ill do it ...

thanks guys for all the help.
