User account disappeared after an OS 10.4.11 update crash!

I think the power went out during a mac update. When I started the computer again, I saw a very old desktop and all my files are missing! Everything has reverted to an older user account? The name of my user account was apple#1, but now it just says apple and does not contain any of my files created in the last year. Maybe since I upgraded to Tiger, not sure.
Is there a way to find my missing user account or my old files! I tried some of the data recovery programs but they are very difficult to use and dont show file names.
Any help would be appreciated,
Thanks,
Dan

Did you try the commands I suggested in the other Topic?

  • Lion server : local user account disappear after power outage

    On the server computer.After power outage I restart server the machine starts up ok.At login screen local user name disappear but there's others account same as client computer.I can log in to network account but can't log in as local.
    In sytem preference local user account is still there.
    I don't want to reinstall lion server .
    What can i do now?
    Thank you for your assistance.

    It sounds like the user directory is damaged. You might try booting into the recovery partition, running Disk Utility, and doing a Repair Volume (and maybe a repair permissions) on the server volume.

  • SOS! User account disappeared after password reset!

    Hi all, and I apologize for waltzing in and hollering for help like this. I have a user with a Mini running OS X 10.4.11, and this morning the user called me over because she didn't know her password. She normally would boot right into single-user, so it was odd that it asked for a pass at all. In any event we tried to figure her pass out for a while with no success, so I grabbed the OS X 10.4.6 install DVD and went to the reset password utility. I reset the pass and started up, and it gave me a login window with non usernames, just a blank username/pass option. I typed in the user's name and pass (I'd just set it not two minutes prior) and got the window shake.
    I repaired permissions and verified the disk, and went back to the reset pass util, which now says there's no user to reset the pass for on that disk!
    This would be a major disaster for me if somehow the user was deleted. Any help at all much much appreciated, if you have anything you can give me. I get notified via email immediately so I'll respond fast.

    Just an update: I went through the restore netinfo db processes, logged into single user, ran the terminal commands, and there was no network.nidb file where it was supposed to be. I ended up going old school and connecting via Target Disk Mode to another computer, copying out the user files (which were still there, thankfully) and reinstalling the whole dang thing. so, solved, I guess.

    I run 3 email accounts on Mac Mail, all 3 disappeared after doing the latest OS X update. I have tried adding the accounts back but no mail appears. Help!

    The mailbox list is divided into categories with headings in caps, such as ON MY MAC. When you hover the cursor over one of those headings (except for MAILBOXES), you should see the word Show or Hide on the right. Click Show. The  MAILBOXES category can't be hidden.
    In each category, the mailboxes are arranged in groups, such as Inbox. To the left of each group is a small disclosure triangle. If the triangle points to the right, click it so that it points down.

  • User accounts missing after system crash

    I have an iMac running Lepoard
    It reset itself possibly it got too hot.
    After it had reset all of the user accounts seem to have disappeared.
    The system goes through startup and presents a Logon dialog. The only user that shows up is a user called Other. This is not a valid user in the system.
    The other piece of diagnostic information is that all keyboard keys during startup are ignored. Have tried getting to a CD boot, single user etc, nothing seems to be acknowledged.
    Any thoughts as to what has happened or how to repair.

    If you are able to I suggest you try a different keyboard for using the key commands at startup.
    I would suggest a good third party repair utility like DiskWarrior or Drive Genius may be your best bet. If you are able to get a keyboard working with the Mac and you have the option then use target disk mode to mount your Mac on the Desktop of another Mac and back it up or if you have a bootable external HD then use that to boot the Mac up and again back up your data. Hardware can be replaced or repaired and applications can be reinstalled but data cannot unless you have a backup so make sure your data is safe first before you tinker too much.

  • User accounts disappeared from Mac Server

    My company uses a Mac Server OS X v10.7.5 which we store all our files on and staff connect to it using a mapped drive (B:). This afternoon we stopped being able to connect, we rebooted the server like we normally do, however, when it came back online all of the user accounts have disappeared leaving only our admin account!
    All of our files and folders are still there, it's just the user accounts used for accessing these folders that seem to have disappeared.
    Coincidently, the + sign under the Users section is greyed out in server.app so I'm having to use Workgroup Manager to add new users. I've tried doing this for myself and given my user account access to the folders that I need however, when I try to map the B: it doesn't recognise my server credentials any more.
    Basically, at the moment, no one can access any files or folders so I'm really hoping that someone has an answer on how to either restore the missing user accounts (if that's possible) or how to set up the user accounts so that we can access the files again.
    Thanks in advance for any help.

    From what I found out it was to do with corrupted Open Directory file, if you've previously archived the Open Directory (through Server Admin) you can restore a previous version or, as we had to do, copied all the server files to an external hard drive and restore from Time Machine, we did it for a point a week ago when it was working and all the user profiles came back.
    If you don't already know how to do that, restart the server but hold down the cmd and R (command key and R key) at the same time until it gives you a screen with a list of restore options, select Restore from Time Machine Backup and select a date from a few days ago or whenever you knew it was working fine, depending on the size of the files on your server it can take a couple of hours to do this. Then copy the files from the hard drive back on to the server so youy have the latest versions again.
    After it had done this all the user profiles were restored with passwords and groups etc..., if you do remove and restore the files then you may need to re-do any file access permissions but other than that it should be back to how it was before.
    Hope this helps and I've explained the process ok.

  • Accounts disappeared after re-installing Lion

    Hello,
    After re-installing Lion, my login accounts disappeared.
    I can only see the Guest account.
    However, when I boot with Windows, I can see the directories of my accounts.
    Currently, I can't login Mac OS.
    Any advise is welcomed.

  • User profile disappeared after reboot

    I rebooted my MBP Retina today. When booted back up I couldn't log in, wouldn't take my password. I booted into recovery mode to reset the password vua terminal. My user profile was not there, so I reset the password of another profile, logged in, checked users & groups again, my profile is not there. WHen I borwse the disk the folder structure of my username is there but profile is not. - Can i recover from this? I do NOT have a time machine backup.

    Hello jimjimk
    All you would have to is go to System Preferences > Users & Groups and then create the user again. Pay attention to what you are creating and at least make sure that the short name is the same name as the folder in the Users folder. Once that is don’t you should see and alert that states A folder in the Users folder already has the name "short name". Would you like to use that folder as the Home folder for this user account?" just say yes, log out and then log back in to the user that was just created and all should be good.

    8. Use the Accounts pane in System Preferences to create a new user with the same short name as the home folder moved in the previous step.
    9. Click OK when prompted with "A folder in the Users folder already has the name  "short name".  Would you like to use that folder as the Home folder for this user account?". This will correct the ownership on all files in the Home.
    10. Log out.
    11. Log in as the user created in the previous step.

  • Lost User Account Settings After OSX Security Update

    After loading the security update, the system booted up into OSX and into my account without asking for a password. Other than having the same dock icons and applications, my account seems to have been cleared. I have no files on my desktop and all my programs are reset, each one asking me to set it up, find registration and serial numbers, etc. The dock was at its default position on the bottom also.
    I found my user account and the settings for it under Shared users on my MacIntosh HD. I don't know how it got there, but all my information is there...I just don't know hot to get OSX to use it instead of the bare bones settings it seems to have chosen.
    Can anyone help me with this? I am still running OSX 10.3.9 on a Mac G4.
    Mac G4 MDD   Mac OS X (10.3.9)  

    The system would not allow me to do this because some files were in use in the account into which I was trying to copy. I had already been looking in the accounts prior to having a response and decided to do the following:
    1) create a new account with a different name - I used "owner"
    2) copy all the information from the old account which I found under shared into the new "owner" account
    3) log out of the account I was on (the labotomized version of my original account) and log on to new "owner" account. Verify links, files, etc...everything was good, just like it had been.
    4) rename the offending account.
    5) rename new owner account back to the old name.
    6) log out and back in the old account name...everything was back with my original account name.
    Might not have needed all those steps, but I can't believe that worked. I was quite happy it worked, but still confused at to how that happened in the first place.

  • User accounts disappearing

    We have laptops running 10.4 that have a issues with accounts disappearing.
    We have the users login via AD plugin. When the user goes to System Preferences and clicks accounts it loads a blank screen. We have tried unbinding them from the AD and logging in with local admin and it still will not show up. We have to do a reinstall. This doesn't happen to all the laptops and it doesn't happen all the time and it doesn't seem to be user specific. Any suggestions.

    Which version of Server are you running?
    For example, About the Mac OS X Server 10.4.2 Update mentions some related issues:
    • Addresses an issue in which Active Directory users who are set as computer administrators may not get admin access to a computer.
    • Addresses an issue in which newly-created accounts may not be able to authenticate or appear in user lists.
    There are lots of articles dealing with Active Directory and 10.4. If you use the "Advanced Search" above you can narrow things down.

  • WLC loses user account database after reload

    The certificate on the Wireless Lan controller had expired.
    I installed the certificate and restarted the controller.
    The controller lost the entire user account database.
    I imported the database from another system and after the reload the database was again lost.
    Apart from this everything else works fine.
    And there are also problems when restoring guest user accounts from Wireless Controll System, WCS the accounts are restored but not the passwords. Also we cannot set expiration date longer then 30 days, we have to set it unlimited first and then change it to limited.
    Please let me know if anyone has come across this kind of an issue.

    Hi,
    I had a similar problem just a day ago:
    A WLC4402-50 crashed and lost all of its database entries (Usernames, PSKs, MAC-Adresses,...). I don't know if it restarted and then crashed, or if it crashed and then restarted because of the crash.
    The crash log contains this lines:
    "Analysis of Failure:
    Software was stopped for the following reason:
    The system has encountered a fatal condition at mmc_system.c:2093"
    Very strange behaviour. I would appreciate any comment, if i have to exchange the hardware or if i shouldn't take any action.

  • User accounts gone after Restoring disk

    Hello -
    I am running OS 10.4.11 on a PowerMac G4 Dual 450MHz Desktop. Recently I purchased a new IDE Hard Drive to put into my computer. I wanted to make an exact copy of my old hard drive onto the new hard drive and use the new hard drive as my main startup volume. I used the Restore tab in Disk Utility to create the copy.
    What happened is that none of the user account data was copied over. Even more strange is that now I cannot find any of my user account data on the original hard drive!
    I used the application "Whatsize" to figure out where all the data is allocated to on the original hard drive. It only accounted for about 25GB of the 30GB of data that are being used on the hard drive. I'm guessing the remaining 5GB of data is what was in my user account, but it can't find it for some reason.
    Anyhow, I guess my question is, how do I recover the data from my user account that I can't seem to find?
    Also, steps I've taken so far:
    - I ran Disk Utility (from another computer using the disk in Target disk mode) to see if I could repair permissions or repair the disk. Neither Repair Permissions nor Verify Permissions were enabled for me to check - only Verify and Repair Disk. I clicked Verify Disk and got a message saying that it had failed and said that "The underlying task reported failure on exit". I then tried to Repair Disk, but got the same error. Disk cannot be verified or repaired.
    - I've also tried DiskWarrior on it, but it doesn't seem to do anything.
    Thanks,
    Steve Pederson

    Hi Steve,
    I found the following in the Apple Help Viewer. Read thoroughly first to see if this might help you:
    Restoring a deleted user account
    If a user's account was deleted and the contents of the user's home folder were saved, you can restore that user's account and the contents of their home folder. Saved items in the deleted home folder are stored in a disk image file (the filename ends in .dmg) in the Deleted Users folder in the Users folder on the startup disk.
    1. To open the user's deleted files, double-click the disk image in the Deleted Users folder in the Users folder on the startup disk. The disk image content appears in a new window.
    2. Note: If there is no disk image for the user's deleted account, no files were saved when the account was deleted. You will need to create a new account for the user.
    3. To restore the deleted user's home folder, open the Users folder on the startup disk and choose File > New Folder.
    4. Type a name for the folder and then press Return.
    5. To copy the contents of the disk image to the new user account, in the disk image file, choose Edit > Select All and then drag the contents to the user folder you created. 
    6. To re-create the deleted user account, choose Apple menu > System Preferences and click Accounts. If some settings are dimmed, click the lock icon and type an administrator name and password.
    7. Click Add + and then type the user name. If you don't want to use the automatically generated short name, type a new short name. (After the account is created, you won't be able to change the short name.)
    8. Type the user's password in the Password and Verify boxes. You may type a hint to help the user remember the password.
    9. Click Create Account.
    10. In the dialog that appears, click OK restore the user's account. The user's home folder will contain all their saved files.

  • Mavericks - Additional User Accounts disappeared

    Hi all,
    I got a rMBP (mid-2012) and recently updated to OS X Mavericks.
    Before the upgrade I had setup a couple of accounts for sharing with the rest of the Macs in the house, namely for screen sharing and a dropbox folder (an actual folder inbetween Macs as opposed to the Dropbox web service)
    These accounts have now disapperead from Settings --> User Accounts
    However the services in the Activity Monitor are still running and the users that initiated them are the users I had setup before the upgrade.
    How can I cease the services from running? How can I delete the accounts and set them up again if they do not show up in the User Accounts panel?

    For whoever has the same issue, this article pointed me towards the right direction:
    https://discussions.apple.com/message/23549345#23549345
    A simple disk verification with Disk Utility brought up some errors.
    All I did was restart, with Command+R and repair disk.
    Now both services and the user accounts have disappeared.

  • User account missing after upgrade to Yosemite?

    I have a mid-2010 iMac which up until recently I had two user accounts on for general use and one for music (Garageband, Logic and audio files etc). After upgrading to Yosemite, this separate user has vanished. I'm left with my original admin account, and a guest login. If I search for any of the files using spotlight, they do show up, but if I try to open them I get the message "you do not have permission to open this document". Also I had folders on the desktop of the music account which contained files, these folders show up in a search but are listed as empty? The files themselves are 'blank white sheet' icons as if they have no application.
    I would assume this is a lost cause if not for the fact that my hard drive (more than half of which was taken up by the 'music' user) still reads as pretty much full up. So have I wiped all this forever?
    Thanks in advance,
    Dave

    retina MacBookPro mid2012. Clean install of OS X Yosemite 10.10
    I'm randomly missing an account at login screen after reboot.
    Sometimes I can fix it with booting into my initial account 'Kevin' (userid 501) and then changing to different login 'Christina' (userid 502).
    But if I log out from my account, the second account is missing. Same if I do a reboot.. This have me in stitches as I ofcause has the need for privacy from each account.
    Both accounts are set up as admins, guest is deactivated.

    userid 501:
    home directory: /Users/Kevin
    userid 502:
    home directory: /Users/Christina
    apart from that... I have loads of problems with Bluetooth, and hand-off only working 1 way (5s with 8.1) where only iOS -> OS X works, not vice-versa.
