I ran Software Update to install the update to Safari (4.0.5), and after it installed, it went into the portion where it needs to restart the computer. Where it installs after the OS shuts down, the update FAILED, and the computer restarted. After restart, Safari and Mail will NOT open, they go straight to the crash report prompt. Airport is connected, but opening Chrome will not get online. I'm led to believe the update corrupted something, because everything errors out, and I can't get anything done. Is anyone else experiencing this problem, or know what the fix is? I really don't want to reinstall the OS (I don't have a backup), but I'm at wits end.
