Change About Dialog (Tweak series)

found a way to change the about dialog, while digging this whole pkg install and uninstall thing, you can learn a lot from it about the way the system is built and how to tweak it.

so, the about dialog found in the login window application folder at:

/System/Library/CoreServices/loginwindow.app/Contents/Resources/MacOSX.tif

the way application/kext/bundle/pkg etc. is built in mac OS X is actually a folder displayed as a file with icon and double click abilities etc. but if you go to terminal you can cd into it, also from Finder you can right click it and choose "Show Package Contents" and a new Finder window will open containing that folders content, every folder usually have the format of single folder ("Content") that contains parameters and config files such as Version.plist and Info.plist and a folder "Resources" that as its name contains the resources of the package or application etc. there you may find images sounds video strings windows and dialog definitions and you can change them (copy them to a different location edit them save them replace them with the backedup original and fix permission and ownership).

lets do this on the About dialog that has an image named MacOSX.tif mine displays iAtkos logo and i want it to look more like a mac so i edited it in photoshop and saved it,

before change it looked like this:

and now it looks like this:

now i am searching for the strings turk team 10.5.1 etc. when i will change it i will update this post, - i dont need it anymore, after updating to 10.5.2 (see next post) my about dialog looks like this:

thats it, if you need a better details on how to copy, move change ownership etc. you can reference this post.

Enjoy.
