This morning I turned on my Hackintosh and was surprised. The user accounts on the machine were gone. Just like that.
After managing some stuff through single-user mode (level 2 init) and freeing space on the HDDs… nothing worked. So I went to ask Google and read posts on Apple Support Communities. Read the source here.
And then I kinda resetted the system. The welcome screen appeared and I could made another user account (admin). From the new user, I switched the sessions and magically all worked.
Now it’s time for restoring HP Scanning support on Mavericks. I have to test the 10.9.2 update.
