Mac OS X 10.3: “/spool/cups/” Alert When Printing or Faxing
Shut down the computer by choosing Shut Down from the Apple menu.
Start up in single-user mode by pressing Command-S during startup.
At the command prompt, type: mount -uw /
Press Return.
Type:
/Library/Receipts/Essentials.pkg/Contents/Resources/CreateSystemUsers
Press Return.
Type: reboot
Press Return.
Ignore the shutdown nonsense…what we want here is CreateSystemUsers
Very handy if you do an upgrade…
