Problem: user password is not accepted after migration

 

 

What I did: Tried to migrate over the LAN, but in the migration assistant the other Mac was mutually never recognized. (Did migrations several times successfully in our LAN before). Last time the LIon Mac was the destination, who is now the source.

 

I backupped then the  user with Time machine on the Lion and installed it with the migration assistant on the Snow Leopard system. As as the password was not accepted, I repeated the backup/migration process once. No help

 

I reset in System Prefs/User accounts the password of that user. But cannot login either

 

First time, that a migration process fails for me.

 

 

Any help is appreciated

 

Thanks

    Try using spaces. If not then you might need to restore your computer using software disks that were included with it. Also here is a trick you can try, Type nothing just as soon as the password window pops up click OK don't type anything. Hope this helps!

    The target computer itself has admin accounts thats not the problem, I can access it. The issue is that the migrated additional user account is not accessible with its password.

     

    I have found here an istruction how to reset a password in single user mode.

    But that does not help either.The answer after the dscl -passwd command is that I do not have access (or similar, I don't remember)

     

    My guess is that backward migration (Lion to Snow) causes the problem. May be I need to create the user freshly and to copy his documents manually

    Boot holding option.

    Enter Recovery HD

    Open Terminal from Utilities menu.

    Enter: resetpassword

    Hit return.

    Select your volume and user.

    Enter new password and restart.

    Update your login keychain password (matches your original login password) or create a new one.

    Just noticed you migrated FROM 10.7 to 10.6.

     

    Erase and reinstall.

    You should never restore a newer backup to an older OS or even System. The Mac OS is not designed to downgrade like that and run perfectly. I'd have been impressed if you had been able to log in at all. Erase your volume in Disk Utility. Reinstall, run updates, then manually bring over only compatible files, if you must, such as pictures, music, movies, documents, etc.

    There is a misunderstanding: I did NOT downgrade the OS system on the target machine. I simply wanted to migrate one user account from a Lion Mac to a Snow Mac. All the rest of the target machine remains untouched.

     

    The goal was to open an account on a second machine for one of our asssistant, which on some days will work at this desk. (of course we can setup a complete new account, but need then to redo all the settings).

     

    But it looks like, that the Snow password behaviour is different from Lion and causes these kind of problems in this source/target situation

    Right, I completely understand. But the point remains, you shouldn't try migrating from a newer OS to an older one. It's never going to work as intended.

     

    Create a new account on the 10.6 and use target disk mode, drag and drop, Dropbox, file sharing, or one of the many other methods of data transfer available in order to bring certain settings or files over.

    Yes, I wouldn't do that either too. I just thought, that migrating only a user account, nothing else, no library, no application etc. wouldn't be something special. But it looks like that a user account is different and depending from the OSX where it was created and not backward compatible
