reset password failed, an internal error occurred

After a reboot my password didn’twork anymore.


I tried restting the password following the steps as in the online manual. However after changing the password the computer gives the following error: An internal error occurred.


How to proceed?

Is this the procedure you used?

Boot into Single User Mode and remove a setup file

  • Restart the Mac holding down the Command+S keys, this will take you into Single User Mode and it’s Terminal interface
  • You’ll need to check the filesystem first:
  • fsck -fy
  • Next, you must mount the root drive as writeable so that changes will save:
  • mount -uw /
  • Now, type the following command exactly, followed by the enter key:

  • This procedure verifies the file system. You would have gotten warning messages if any problems were found with the file system. I'd expect some warning if there was a problem with the drive. It's still possible to have a bad drive with no warning messages.


    The next step is to rebuild the accounts database. What version of macOS do you have? I'll have to look around for how. Rebuilding the database may have changed over the years.


    How old is your mac? Harddrives start goin' bad at three to five years. You could get an external drive and install macOS on it.

    Do you have backup? if no, and you need to recover your data. See this link:

    backing up from the command line via single user mode.
