I updated OS-X and iTunes and ever since then I have rec'd hundreds of pop-up messages that say "Mac OS X needs to repair your Library to run applications.  Type your password to allow this."  Whether I cancel the msg or type my PW, the box pop up again within seconds.  When the box is up it immobilizes my computer until I cancel or attempt to repair again.  This is an awful bug, worst I have encountered on an Apple computer.  I did a DIsk Utility / Repair permissions command and it did not help, though it did find some permissions that needed to be repaired, which I did, to no avail.

    Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.

    This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.

    Step 1

    If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.

    Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):

    { sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null

    Launch the Terminal application in any of the following ways:

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

    Paste into the Terminal window (command-V). You'll be prompted for your login password. Nothing will be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.

    The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.

    Step 2 (optional)

    Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.

    Boot into Recovery. When the OS X Utilities screen appears, select

    Utilities Terminal

    from the menu bar. A Terminal window will open.

    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 will open. You’re not  going to reset a password.

    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.

    Under Reset Home Directory Permissions and ACLs, click the Reset button.

    Select

    Restart

    from the menu bar.

    Three steps to fix this problem:

     

    1. Restart your computer with Command-R held to load the Recovery HD

     

    2. Open Disk Utility, choose your hard drive, and run a permissions fix on the boot drive with it.

     

    3. Quit Disk Utility and then choose "Terminal" from the Utilities menu. Then enter "resetpassword" (all one word, lowercase) and in the tool that pops up, select your hard drive, then your user account from the drop-down menu, and finally click the button to reset home folder permissions and ACLs.

     

    When finished with these three steps, restart the computer and try logging into your account again.
