Leopard Install Hangs (Blue Screen)


I have installed Leopard iAtkos r1 10.5.1 on a dell d620 Latitude, after the install finished and it was the moment to see the desktop or the login screen it simply hanged (nothing but a blue screen appeared), the mouse moved and it looked like something is working but no desktop exist.


the image at the top of this post is of that state, the problem is that the LoginWindow.app has crashed for some reason, this is the application that should display the login screen and after validation will transfer you to finder and desktop.

the solution is one of two:
ether you simply reboot and you will see the login screen, or that you need to copy a healthy application (from a working hackintosh) into your hard driver (recently installed leopard).

in order to copy the LoginWindow.app perform the following steps:
1. download the application or get it off another leopard dvd copy (different install DVD but not apple Leopard original one, it has to be hackintosh), you can find one in this link.
2. you can also extract it from a working hackintosh, it is found at: /System/Library/CoreServices/loginwindow.app
3. copy the extracted application into a USB disk on key or CD/DVD
4. boot into your new Leopard into single mode see here how
5. next insert the USB Disk On Key CD/DVD so the leopard will identify it
6. CD into it like this: cd /Volumes/Untitled (for example, use Tab key for auto complete so you can see what mounts are available at Volumes folder and CD into yours)
7. delete your original loginwindow.app like this: rm /System/Library/CoreServices/loginwindow.app
8. copy the application into your CoreServices folder like this: cp -R loginwindow.app /System/Library/CoreServices
9. fix permissions like this: chmod -R 755 /System/Library/CoreServices/loginwindow.app
and another command: chown -R 0:0 /System/Library/CoreServices/loginwindow.app
10. reboot

that should be it.
Enjoy.
