Can not login by blank password

[zenkarsha]

I'd reset my macvm password to empty pwd, after restart vm, it can not login by simply press enter button.
But it can pass the recovery choose disk asking permission password dialog.

Open vm by recovery mode and open terminal, then check your folder, and use script like:

dscl -f "/Volumes/Macintosh HD/private/var/db/dslocal/nodes/Default" localonly -passwd /Local/Target/Users/myusername PASSWORD

it will need you to insert your old password (the blank password), if it didn't work, try again.
