This happened today, and I am writing this in case someone else have the same issue.
I have a corporate MAC, have separate password for Corporate and local password for the MAC.
Everything was fine, today the password stopped working, I was sure it is the password, won't work.
What didn't work…
- Single User Mode -> Setup Assistant -> New User -> Login as new user ->
sudo passwd <myusername>
. Threw an error about authentication method not acceptable. - Tried to reset from
Users and Groups
. TheReset Password
button was not even there. - Tried entering wrong password multiple times to trigger Apple ID reset, nothing.
- Command+R for Recovery mode didn't even take me to Recovery Mode.
Machine Specs:
MacBook Pro (Retina, 15-inch, Mid 2015)
