Hi. I could install and run Big Sur easily following the instructions on the README but It seems I have a common problem with Big Sur. I can log in with the admin password I set during installation but I cannot use that password when the system asks for the admin password.

I followed the steps in this video:

but I'm getting the same error even if apparently I could change the password without any problem.

I guess the problem does not have anything to do with this repo but if it's a common and deterministic problem we can add the fix to the readme if someone knows how to fix it.

Hi @sickcodes that does not work. It seems it's a Big Sur bug:

https://www.reddit.com/r/macsysadmin/comments/kv7t83/administrator_password_not_working_on_big_sur/
https://appletoolbox.com/cant-enter-your-password-in-macos-big-sur-heres-how-to-fix-it/

I installed Catalina and then upgraded to Big Sur.

It seems it only happens on T2 chip macs. I have a Lenovo ThinkPad with Ubuntu 18.

I haven't tried option 2 and 3 on this article yet:

I've only tried the option on the youtube video I wrote below.

Hmmm weird bug, I will see if this affects us and why. If it does, I'll make the change
