The updater came up and the update was unsuccessful. It was still running. Turn off the computer. It would not boot up. The progress spinning wheel just stops, and no HD activity (by that I mean sound). I tried holding X it would not work. I tried safe boot (shift) it would not do it. The firs few times, it would show me a kernel panic, the we are still hanging there type. But the last trials it hasn't gone to panic. I tried osx dvd it would not run it. I have a partition and in it I have os9.2. I have run it and it boots up, but eventually freezes. I have done Target mode and erased all these files that way: com.apple.kernelcaches (a folder in /System/Library/Caches) Extensions.kextcache (a file in /System/Library) Extensions.mkext (a file in /System/Library/) com.apple.ATS (a folder in /Library/Caches/) com.apple.loginwindow.plist (a file in /Library/Preferences/) Files that start with com.apple.LaunchServices (in /Library/Caches) I also run disk utility in target mode. The HD seems to be fine. I have come to think that the update corrupted the firmware: is it possible? What should I try now?
