After a nasty crash of VMware's Fusion while copying files across the network (crashed both the VM and the Mac OS host, had to hold down power button to reboot) I have the following issues: Mac OS starts, but although I can select folders, I can't open any. The right-click menu selection comes up, but can't open folders. I cannot start any programs in the Dock. Clicking on a program icon highlights the icon briefly, nothing happens. The menubar is unresponsive. I cannot select anything, including the System shutdown. If I press the power button briefly, the system shutdown/logout/restart dialog box appears, but I can't select anything. I can only hold down the power button to kill the power. But the startup 'boing' seems to have gone altogether. Booting into safe mode does not help (it just takes a lot longer to boot). Sometimes on booting I get the error "The application Dock quit unexpectedly" but I can't click any of the choices (Ignore, Report or Relaunch) it's as if there is no keyboard or mouse input (though there is still in some other contexts). The right-click on the mouse is about the only thing that seems to work, but I can't do much with that. If I select 'Open' on a program icon or folder, nothing happens. I can use the tab key to move around the various desktop items, but can't open anything. I tried booting on a Firewire Disk and repairing the startup disk. Took over an hour and didn't make any difference. Safe Mode still doesn't make any difference. Now the 'biong' on startup seems to have disappeared. Something very bad seems to have happened but I don't know what it is. Fortunately I can still boot up on a Firewire disk (it's a clone of my OS at an earlier stage) and I can access my files that way.
