I have a brand new iMac, and I've been using the same initial password I set up since I got it. Only yesterday morning I changed passwords, and throughout the day I was able to login fine. Yesterday evening I came home and tried to login after the iMac had been asleep, and it wouldn't accept my password. I tried both my old and new ones, and tried restarting, but that initial login page will not accept the password.


What do I do? There's only the one account on the iMac and I can't get in at all right now!

    If you can't login, try these simple solutions :


    • Did you checked your typing? (maybe just a typing error)
    • Check your keyboard. Try using a wired keyboard if possible.
    • For wireless keyboards : check for Bluetooth interference around you.
    • Try waiting after keystrokes. For example, if your password is "hello", then type your password one letter at a time, waiting for about a second for one character, and make sure when you've entered your password, you wait for about 2 seconds, and then hit enter.


    If all of these solutions don't work, you'll need to reset your password. Check out this link for solutions :

    You have a brand new iMac. I assume that it ships with OS X Lion, or Mountain Lion, right?


    In this case, you might need to try using recovery mode. The instructions and explanation is here :





    Or, to reset your password : Follow these instructions :


    1. Reboot the computer, holding down the command and 'S' key at the same time. Wait for about 10 seconds
    2. You'll see a command-line interface. Type down commands, as listed below (step by step) :



    mount -uw /


    launchctl load /System/Library/LaunchDaemons/


    ls /Users


    passwd (your username here)



    After you've typed the passwd command, and hit return (or enter), enter your new password for your account. After that, simply type in more commands, listed below step by step.



    rm -rf /Users/username/Library/Keychains/login.keychain





    The system will reboot. Try logging in with your new password, and see if it works.




    NOTE : The following code deletes the password saved in your login keychain. However, if you could not log in, this may be the only way to prevent you from losing your documents, as you may have to re-format the computer.
