View Full Version : can't log in

23rd January 2006, 10:46 AM
we had a power failure and now my imac is much slower than usual to start up and refuses to let me log in with *what i know to be the username and password*
it thinks about it for a really long time and then does the shaking thing
i have repaired permissions with disk utility which didn't help
when i try the reset password utility it seems to think there are no users on the volume
everything looks normal when i start up from an external hd
i'd be grateful for any ideas

I'd be chucking the abridged question at google in a variety of formats, and always with "osx" somewhere in it.
I'm helping out a mate who's forgotten his password lately and can't install anything, and I suspect the resolution will end up in some single user mode code.

good luck,

don't know if this will work but try resetting the pram 3x in a row. If you can get to your ram chips, pull them out, then put em back in and then zap the pram 3 times and see if that helps.
If that doesn't help then this should. "this" ('http://www.macosxhints.com/article.php?story=20001217230925152')

Edit: that link actually is rather old so I will give you another newer link here (http://www.intelliot.com/blog/archives/2005/02/15/mac-os-x-password-recovery/)
Let us know if that helps.

(sort of)
only about two hours wasted :)
and learned something
thanks everyone for your responses unfortunately no joy from any of your suggestions
ended up removing the applesetupdone file through terminal which makes the machine behave as if ... you guessed it ... as if you've just installed a new system
this is the apple knowledgebase article which helped me to figure it out
and now it's off to buy myself a ups

for those that are interested i ended up here (http://episteme.arstechnica.com/groupee/forums/a/tpc/f/8300945231/m/633001937731) and it seems to have been a partial corruption of the local NetInfo directory

now i am a virtual unix virgin but i can understand that if you had a backup you could just :
- move /var/db/netinfo/local.nidb (of the backup volume, NOT YOUR BOOT DIRECTORY) to a new directory
- remove the /var/db/.AppleSetupDone file
- boot from the backup
- recreate your userlist as it exists on the original drive

if you are like me remove the references to backup and create the file again from scratch
the only disadvantage is that you have to sit though that awful apple introductory video with the horrible music :(
