I am using macOS high Sierra. By mistake I converted my admin account to standard user account. Now by entering into the single user mode and trying to mount the disk,it shows message that "devise is write locked " and "IO failed , error = 13" and trying to remove the apple set up done file the error message is "no such file found." Please guide how to resolve this situation.


What were you doing when you "converted" the account type? There is no need to re-run the setup. Just toggle the checkbox in System Preferences > Users and Groups > Allow user to administer this computer.

  • You can only do that if there is an administrator to authorise it... otherwise what would be the point of having a standard user? – Tetsujin Feb 25 '18 at 18:37
  • So your interpretation of this problem is that there was a single Admin account and the user somehow converted it to Standard? That's not supposed to be possible but I never tried. – telliott99 Feb 25 '18 at 18:46
  • It's done often enough, which is presumably why the OP was attempting the 'applesetupdone' trick - apple.stackexchange.com/search?q=applesetupdone – Tetsujin Feb 25 '18 at 18:56
