Command+S At Boot Doesn't Activate Single-User Mode 10.6.8. Hold down Cmd+S throughout the entire boot process. It always goes to the regular login screen and starts doing the "stop holding down buttons" chime. Why?
Figured it out. I'd changed my keyboard layout to Dvorak which apparently isn't honored at boot, defaulting to QWERTY. I pressed Cmd+O (where the S would've been) and it worked.
