Was doing the software update yesterday, and this borrowed iBook I have hung while "Installing Quicktime." It sat there with the progress bar at the same point overnight, and the cursor was the pinwheel the whole time... couldn't do anything. So I shut it off, rebooted single user, ran fsck and rebooted again. Now when trying to log into either of the admin accounts on the machine, it takes the password, but just sits there with the progress bar in motion. On single-user boot, I get the following errors: verifyCompatibility(): Extension "com.apple.iokit.IOSCSIArchitectureModel" cannot be found. getDependencyListForKmod(): Dependency com.apple.iokit.IOSCSIArchitectureModel of com.apple.iokit.IOSAMUserClient is not compatible or is unavailable. load_kernel_extension(): Can't get dependencies for kernel extension "com.apple.iokit.IOSAMUserClient". IOCatalogue: com.apple.iokit.IOSAMUserClient cannot be loaded. find didn't find com.apple.iokit.IOSCSIArchitectureModel searching from the root. Any chance I can fix this at the command line?
