macos – Up to date from El Capitan to Sierra (10.11 to 10.12) and now no login passwords work

I’ve an older Mac Professional that I’ve been that means to replace for fairly a while so I downloaded the Sierra installer and up to date it.

It seems the replace goes high-quality and the system restarts however none of my passwords for any of the accounts on the pc will work.

I’ve tried utilizing my Apple ID to reset the passwords, it seems to occur however it by no means works.

I’ve tried utilizing the “Grasp password” which I do know I’ve proper as a result of if I depart off a personality it tells me it’s fallacious. I click on the Change password button however nothing occurs.

I’ve tried utilizing the resetPassword instrument in Restoration mode. It says it modifications it however when it reboots it doesn’t repair the problem.

I’ve tried the delete var/db/.AppleSetupDone trick and all that will get me is a black display screen on boot and the one method round it’s to revive or copy the var/db/.AppleSetupDone file from my Time Machine backup.

I’ve tried updating to Excessive Sierra however that made no distinction.

I’ve restored again to a Time Machine backup about 7 instances making an attempt all the pieces:

  • FileVault on: when beginning up, it accepts the FileVault password however after that, it doesn’t settle for any of the account passwords.
  • FileVault off. Identical, no distinction.
  • I attempted to set auto login for all of the accounts however that doesn’t work after the replace.
  • I’ve tried creating a brand new admin account earlier than updating with a brief easy identify and a brief easy password however it does the identical factor.

I can’t discover any answer or hack for this.
