Hi all,
I'm running into a problem with my father's MacBook Air. I think it's a 2019 model with intel inside.
He was doing the latest Big Sur update, but half way there was a power outage. After this the laptop stays in the update cycle.
When you restart you get the login screen where you have to fill in your password. Next you get the loading bar with a Big Sur Background for 10 seconds and then the screen goes black with a loading bar at 90%. And that's it. It doesn't complete. Even after 24 hours it's still the same.
I tried PRAM and TMC reset. The only thing this does is that the loading bar in on the black screen is not at 90% but at 10%.
I tried restarting in Safemode. (Shift). But this is incredibly slow (like almost not responding), and it only gives me the options to reinstall macOS or to Reinstall from a backup.
I think there is a firmware password installed which limited my options. But is there anything else I could try.
Thanks. Jonas
