Hello, this is starting to worry me a lot.

 

I had a pending update in the Apple store for OS 10.8.4 (not exactly surei remember the number correctly but it was the last one)

I proceeded with the update via the apple store and left. I came back around 7 hours later just to see my Macbook sitting on the gray Apple logo spinning wheel screen (the one you get after a reboot usually for a few seconds). I found it strange and I waited around 1 more hour but nothing happened so I decided to reboot my computer. Since then I am kicked out of my computer. I am prompted with the login screen asking me for my user password but it won't work when using the right password. I even changed the password using terminal/passwordreset/ and nothing. I even managed to create a new user and right after creating it I get the login screen which asks me for the password I just created and when I type it in it won't work.

 

I don't really know what else to do. when I reboot with cmd+S I can see my users and files there.I did a disk check and it said it was ok,but the os is not taking the right passwords.

 

I don't have a lion disk as it was bought on the Apple store.

 

Anyone know what else can I do? Any tip will be much appreciated

    When you enter your password, does the window shake from side to side?

    First, make sure caps lock is not on.

    You must back up all data before continuing, unless you've already done so. If you need to back up but can't log in, ask for instructions.

    If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.

    Otherwise*, boot into Recovery mode. When the OS X Utilities screen appears, select

    Utilities Terminal

    from the menu bar. In the Terminal window, type this:

    res

    Press the tab key. The partial command you typed will automatically be completed to this:

    resetpassword

    Press return. A Reset Password window opens.

    Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.

    Select your username from the menu labeled Select the user account if not already selected.

    Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.

    Select

    Restart

    from the menu bar.

    You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.

    *Note: If you've activated FileVault, this procedure doesn't apply. Follow instead the instructions on this page:

    If you forget the password and FileVault is on

    Please read this whole message before doing anything.

    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.

     

    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
       
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

     

    Test while in safe mode. Same problem?

     

    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

    Back up all data, if you don't already have a current backup. You can back up without being able to log in. Ask if you need instructions.

     

    Boot into Recovery mode. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.

      

    If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

    I just completed a downgrade to snow leopard

     

    That wasn't what I suggested. I can't help with a Snow Leopard problem. Good luck.
