Password Reset[edit | edit source]

I was frustrated for over an hour trying to get into single user mode on a mac which was running under VMware. Supposedly, you're suppose to hit ⌘-S while it is booting in order to get into the rescue mode. However, this doesn't seem to work, at least on my PC keyboard (I tried hitting Win-S and Alt-S) through VMware Workstation 8.

Instead, try:

  1. Restarting the VM
  2. hitting F8 while booting Darwin/x86.
  3. At the boot menu, select the hard disk option (h)
  4. Specify the boot parameter '-s' for single user (just like linux)

That should boot you into single user mode, allowing you to reset your password amongst other things.

To reset a password:

# umount -uw /
# launchctl load /System/Library/LaunchDaemons/
# dscl . -passwd /Users/username password
## You may see an error, but it should be fine.
# reboot
