Reset OS X Password Without an OS X CD

I wrote about this a while back on my blog, hackaddict, but it was such a popular post I thought I’d give it a revisit. A lot of people buy used Macs, and they often run into the problem of not knowing the admin password, so here is a way to get around not knowing the admin password on Macs.

To reset your OS X password without an OS X CD you need to enter terminal and create a new admin account:

  1. Reboot
  2. Hold apple + s down after you hear the chime.
  3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):
    • mount -uw /
    • rm /var/db/.AppleSetupDone
    • shutdown -h now
  4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and you’re good to go again!
