As indicated in red before:
4. The problem now is that all characters typed show as Capital letters, with the Caps Lock or Shift keys pressed or not. Absolutelly all. Which rendered the username and password not valid.
Such Mac has been idle on such screen since then.
Thanks for the backup information. I always backup the whole Mac with Time Machine when all applications are closed (shutdown, not suspended -- I never use that). Is that safely done for the whole VMware Fusion disk images? Should I use other application like SuperDuper! or is it better to do a manual drag and drop of the VMware Fusion disk images over the backup disk? Thanks again.
