    Im having a little problem with my Macbook Black.
    every time i try to open a system preference panel i get the following message

    'There is no default application specified to open the document Accounts.prefPane'

    this happens even when i try to load other preference panels. I only bought the macbook last week from some one and i dont know what they have done or if there is any way to fix this issue.

    thanks

    Hi,

    Start with resetting the LaunchServices database.
    Launch the Terminal.app in /Applications/Utilities/, copy & paste this one-liner into the window that pops up, hit the return key, and when you get a new prompt, quit the Terminal app and restart:

    Code:
    /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user
    Question : which OS are you running ?

    I'm currently running Snow Leopard

    ----------

    All i get back from Terminal after i hit enter is
    'ThrottleProcessIO: throttling disk i/o' ??

    Which version ? 10.6.8 ?

    Anyway, the command above is the right one (just checked the path on my Snow Leopard partition).

    yes, 10.6.8.
    just did a restart and now when I search for preferences using Spotlight I just get a folder open up in a finder window...

    Try this (in an admin account) :

    Code:
    sudo /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user
    Type your admin password when prompted (won't display), then hit Enter, then reboot.


    Just seen your last message : do you still have the "System Preferences" app in your Applications folder ?

    did as instructed and still the same.
    And no, its no there. If i do a clean install with a Snow Leopard disk will this resolve the issue?

    Yes of course a clean install of SL will solve the problem.

    However, you'll need to :

    - backup all your data (Time Machine, clone)
    - erase your Macintosh HD partition
    - install SL
    - upgrade to 10.6.8 via the Combo update
    - run Software Update for security updates
    - migrate all your stuff

    This is a lot of work...

    You can also re-install the system without wiping out the disk and without losing your data, apps, settings.

    Before you do this :

    - have you any idea of what created the problem ?

    - do you have a Time Machine backup ? If yes, restore System Preferences.app from it.
    - or try using this one (from my SL 10.6.8) :

    Unzip the download and place it in your Applications folder.
