Hack your forgotten Mac Login
Mountain Lion Login Screen

If you have a system that you forgot the password to, or a used system you bought that has a persons forgotten login account information, here's a simple hack you need.

Notice: Performing this hack will restore your system to factory defaults and will erase all data pertaining to the current account; avoid this hack if you are simply trying to restore an old account with its information preserved.

Simple steps:

  • If the system is already on, restart it then hold the following key combination upon startup: COMMAND (apple symbol key) + "S"
  • If your system is turned off, turn it on and hold the key combination upon startup: COMMAND (apple symbol key) + "S"
  1. Press "return" once.
  2. Type the following command: mount -uw /
  3. Press "return"
  4. Type the following command: rm /var/db/.AppleSetupDone
  5. Press "return"
  6. Type the following command: shutdown -h now
  7. The system will shutdown now (power off).
  8. Turn your system back on and it will now load the factory welcome screen where you can walk through instructions to setup your system as if it is brand new out of the box.
