Mountain Lion lockscreen when trying other startup options
Hi guys,
Facing this problem when I'm trying to boot from another startup disk (e.g. do a recovery install on the mountain lion system):
I do the command+r or the option holding while booting on my Macbook Air, and I simply get this lockscreen asking for a password and neither my masterpassowrd / onlyuser-admin-acconut-password work for it.
What on earth is this screen / what kind of password does it require then lol? My other computers have no screen when trying to do the same.
Picture to this:
