I'm using a 12" 1.33ghz G4 PB that was previously working fine w/ 10.5.5. This evening, I installed the 10.5.6 update; left Software Updater to download the package (i actually took a 30-minute nap while it downloaded as I have fairly slow DSL connection) and then allowed it to restart the machine to perform the install. I then showered and when I returned the machine had already rebooted and was showing the log-in screen (the log-in box/windows displayed 10.5.6 when I clicked). I entered my password and waited to log-in. However, the Leopard background/splash screen (the space image or whatever it is) remains and a mouse cursor is the only thing visible on-screen. I've physically rebooted several times and tried to login to no avail. I pulled out the Leopard install disc to run Disk Utility, repair permissions, and verify the disk. However, I'm still stuck with only the background image showing and no access to my desktop. Interestingly/fortunately, I noticed that I'm able to access the machine's hard drive/files through smb/unc shares on the windows desktop that I'm currently using. Any ideas as to what I can do?
