I'll keep it simple.  Basically, I forgot the password to my Mac.  A friend helped me regain access to my Mac by creating a new keychain.  I'm now left without Messages, FaceTime and even Mail sometimes.  They keep asking for my password to the "login" keychain that I don't remember anymore.  Please help, I spent a lot on this thing and I was expecting it to have all the features functioning like the guy in the Apple Store told me. HELP!

MacBook Air, OS X Mavericks (10.9.1), Baseline, 11"

    Find a new friend to help you. Changing your password if you forget it doesn't require creating a new keychain:


    Forgot Your Account Password


        Boot to the Recovery HD:


    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.


         When the menubar appears select Terminal from the Utilities menu.

         Enter resetpassword at the prompt and press RETURN. Follow

         instructions in the dialog window that will appear.


         Or see:

           OS X Mountain Lion- Reset a login password,

           OS X Mavericks- Solve password problems,

           OS X Lion- Apple ID can be used to reset your user account password.

    Tutorial: Resolving Keychain Issues


    If you can't access your keychain, or forget your password If you can't get into your keychain file because you've forgotten your password or the keychain file appears to be corrupt, there are a couple of options.


    First, if you've forgotten your password, you can use the "Keychain First Aid" utility to make the keychain password the same as the login password. This can be accomplished via the following process:


      1. Open Keychain Access (located in Applications/Utilities)

      2. Go to the "Keychain Access" menu and select "Preferences"

      3. Click the "First Aid" tab

      4. Make sure the "Synchronize login keychain password" box is checked

      5. Close the Preferences window

      6. Go to the "Keychain Access" menu and select "Keychain First Aid"

      7. Enter your username and password

      8. Click the "Repair" button


    The second option is to completely delete your keychain then recreate it. This routine is useful if your keychain appears to be corrupt or otherwise inaccessible. This can be accomplished as follows:


      1. Launch Keychain Access (located in Applications/Utilities)

      2. Click "Show Keychains" in the lower-left corner of the window.

      3. Select the problematic keychain from the left-hand pane.

      4. Navigate to the "File" menu and select "Delete Keychain '(name of keychain)'"

      5. Check all options for deletion and press "OK"

      6. Create a new keychain by going to the "File" menu, then "New" and selecting

          "New Keychain"

      7. You can now make this keychain your default if you desire by selecting it, then

          going to the "File" menu and selecting "Make '(name of keychain)' Default"


    Login as root and perform repair In some cases, problems with keychains can only be resolved when logged in as the root user.


    First, you want to enable the root user:


      1. OS X Mountain Lion: Enable and disable the root user

      2. OS X Lion: Enable and disable the root user

      3. Mac OS X 10.6: Enabling the root user

      4. Enabling and using the "root" user in Mac OS X


    After enabling the root user, and logging in under this account, again open Keychain Access. First attempt repairs using Keychain First Aid, and failing that, delete then recreate the keychain as described above while logged in as root.


    Persistently asked for stored passwords If you are persistently asked for passwords in various applications that you have specified should be remembered in a keychain, your "login" keychain may not be active for one reason or another.


    Navigate to ~/Library/Keychains/ (this is the Library folder inside your user's home folder). Find the file named "login.keychain" and double-click it.


    Failing that, select the "login" keychain within the Keychain Access application and make sure it is the default keychain by going to the "File" menu and selecting "Make 'Login' Default"


    Turn off Keychain synchronization in applications having problems If specific applications are experiencing issues when accessing password-protected material, the Keychain may be to blame.


    The above comes from an article published on MacFixit.com.

    If you cannot fix the problem with the information previously posted, then you can give this a try:


    How to Create a New User Account if You Cannot Access Your Admin Account


    Reboot the computer. At the chime press and hold down the COMMAND-S keys to start into Single-user Mode.


    You will boot to a black screen with scrolling white text, release the keys and wait for it finish.


    Enter the following lines at the command prompt pressing RETURN after each:


         mount -uw /

         rm /var/db/.applesetupdone



    After you reboot the computer you will be taken to the Setup Assistant. When you get to the point where you are asked to setup your new user account, create a new admin account. Be sure to name this user account something different than the admin user account that already exists on the system. When you finish the Setup Assistant, it will automatically log you into the new account.


    You can transfer your files from the old account to the new one. See: Transferring files from one User Account to another. Once you have moved all your files into your new account, you can delete the old account using Accounts or Users & Groups preferences.

    Thanks, but I figured it out. Turns out there were issues with both my disk and keychain permissions. Thanks for the info though! This could be useful if something wrong happens.

    Your problem, hardware or software, may not be exactly the same as that of the original poster of this older thread, and it can be very confusing for everybody if we try to answer more than one question in each thread, which can also result in you applying the wrong advice to your particular problem.


    In order for us to give your problem our proper attention to try to solve it, would you kindly start your own thread, describing the trouble you are having in the fullest detail, including completing your details to show what Mac or iDevice you are using, what operating system, and what version of the application in question. Please remember to post in the forum relevant to your hardware or version of OS X. A full list of all the support forums is here:
