Certain files under System Preferences won't open

When I open System Preferences and try to open the files 'Security' 'Sound' and 'Mouse and Keyboards' I only get a message telling me that the file can't be opened due to an unexpected error. All of the other files in the folder work fine, but these three don't, at all. I bought my macbook a week ago and everything else works great, I just can't access a few preferences.

Use your Disk Utility App to Verify your hard drive's Disk Permissions then run the Repair the Disk Permissions option.
Not promising that will fix it but the procedure should reconnect all your internal functions and features.
Also, download Onyx, a free OSX maintenance program, that you can set up to run automatically (say late at night when you are asleep) and to run other maintenance procedures which may also correct the problems.
If that fails then the next option is a reinstall of OSX from your original backup OSX CDs (found in your MacBook box).
Hope this helps!

  • Try to change table image but system preferences won't open

    Hello all. I need your help. My table image got all blue. Itried to change it but the system preferences doe not open. What should I do?

  • "Accounts" in "System Preferences" won't open

    I am trying to access the "Accounts" window in "System Preferences", but it won't open.
    I am getting two messages:
    "To use the "Accounts" preferences pane, System Preferences must quit and reopen."
    I clicked on "Ok"
    *Preferences Error*
    Could not load Accounts preference pane.
    I have restarted and shut down my MBP to see if that helped. Didn't work. What am I suppose to do?

    I have the same issue and I have tried everything. I really would love to resolve this System preference error as well! It will take me forever to reload all of my pro apps and even longer to restore my user settings. This almost makes backing up your data impossible if re-installing is the last option. I've tried restarted in safe mood. Trying different admin rights, trying to extract the corrupt files using pacifist, repairing disk, I've had this issue for months and I have had no luck with finding solution. Any one for more solution ideas?
    I also came across this with working with Apple Remote Desktop!

  • Help! Qmaster System Preferences Won't Open

    I just performed a clean install of Final Cut Studio 2 on a brand new MacBook Pro. All of the software updates have been downloaded, etc. When I try to launch Qmaster in the System Preferences (to set multiple instances, etc.) the System Preferences immediately quits and I am presented with an error message. Despite repeated attempts to "Relaunch" I am still not able to open the Qmaster preferences. Thanks very much in advance if anybody can help me solve this problem.
    - Jordan

    hi Jordan, have you tried to
    1) +repair disk permissions+ (/apps/utils/disk utility.app)?
    2) Also you may want to go in to the root file system wee you are having the issue :
    /Library/Appliction Support/Apple Qmaster
    and delete|purge|erase|discard|etc any of the plist files such as ..
    QmasterApplications.plist
    contentcontroller:com.apple.qmaster.contentagent.plist
    hostperfscore.plist
    jobcontroller:com.apple.compressor.cluster.admin.plist
    jobcontroller:com.apple.qmaster.cluster.admin.plist
    qmasterservices.plist
    requestprocessor:com.apple.qmaster.contentcontroller.plist
    servicecontroller:com.apple.qmaster.executor.plist
    servicecontroller:com.apple.stomp.transcoder.stomp.plist
    servicecontroller:com.apple.stomp.transcoderx.plist
    and restart qmaster again.
    It worked for me, but it was quite frustrating to have to do this.
    3) If it persists, then as many have suggested use PACIFIER.app as last resort to reinstall QMASTER.app from the FCS or SHAKE installer DVD set.

  • System Preferences won't open in Mountain Lion

    I upgraded to Mountain Lion yesterday and when I went to open System Preferences, I got this:

  • Preview missing -  no menubar clock - System Prefs won't open....help!

    Wow. Preview is missing (it shows up in the Application window as a zero K app, then when I click on it, it vanishes), all the Preview docs I had on my desktop are neutral icons ( just a white rectangle), and also my menubar clock is gone. System Preferences won't open. Help! I've tried repairing permissions but that's as far as I know what to do. Thanks, Chris

    Wow, I feel a tiny bit proud of myself. And actually, Disk Warrior eventually helped,in a circuitous way. I reloaded the Combo Update for 10.3.9, that seemed to rejuvenate Preview. But still no System Prefs, no menubar clock. I right-clicked on System Preferences ( that
    right-click or option-click is really useful sometimes, because it can open
    packages and other single-icon deals that you can't see into otherwise - I
    really recommend a 2-button mouse, I was resistant to it after 20 years of Mac-ing but the 2 buttons combined
    with a scroll wheel is way better than the Apple mouse and the Dell mouse
    is about 10 bucks on eBay)... once that was cracked, there was a Terminal
    icon which I clicked on... wwhich indicated that there was a
    pref file it couldn't find. When I searched for it with Find, there it was
    in the 'REscued Items" folder from DiskWarrior. Dropped it in where the
    Terminal readout indicated it was missing, and voila! A restart, and I
    have System Prefs again and a menubar clock. The only thing still FU is
    that shift-3 isn't working to get a snapshot of the screen so in order to
    generate a PDF from the screen I have to use Grab and finagle there. I
    have a feeling, though, that I'll find a way to fix it now. And as you
    know, sometimes these things weirdly self-correct after a while, a few
    dozen restarts, whatever. At any rate if that's all that I have to contend
    with it's not a big deal. So -= DW helped in the end! Thanks to the respondents on this issue- C

    My System Preferences won't let me open accounts? I really need it to work please help. Hugz and kissez Abbyxoxo1010

    Hello Makena Little,
    It sounds like you are unable to change your wallpaper background because that section of your System Preferences says that it is loading adn will not finish. I recommend performing a Safe Boot, then leaving it and retesting the issue:
    OS X: What is Safe Boot, Safe Mode?
    http://support.apple.com/kb/ht1564
    Starting up in Safe Mode
    To start up into Safe Mode (to Safe Boot), follow these steps.
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key.
    The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple logo and the progress indicator (looks like a spinning gear).
    After the logo appears, you should see a progress bar during startup. This indicates that your computer is performing a directory check as part of Safe Mode.
    To leave Safe Mode, restart your computer without holding any keys during startup.
    Thank you for using Apple Support Communities.
    All the best,
    Sterling

  • Many of my System preferences won't load in mavericks?

    Since updating to 10.9 many of my system preferences won´t load. These are:
    - Security: You can’t open Security & Privacy preferences because it doesn’t work on an Intel-based Mac.
    - Notifications: Could not load Notifications preference pane.
    - Printers & Scanners: Could not load Printers & Scanners preference pane.
    - iCloud: Could not load iCloud preference pane.
    - Internet accounts: Could not load Internet Accounts preference pane.
    - Networks: Could not load Network preference pane.
    - Sharing: You can’t open Sharing preferences because it doesn’t work on an Intel-based Mac.
    - Users & Groups: You can’t open Users & Groups preferences because it doesn’t work on an Intel-based Mac.
    - Parental Controls: Could not load Parental Controls preference pane.
    - Date & Time: You can’t open Date & Time preferences because it doesn’t work on an Intel-based Mac.
    Any hints on a solution are greatly appreciated!
    Best regards, Mikkel

    To further explain:
         I didn't need to locate any invisible files in my case.  I discovered that I had 4 versions of the System Preferences application on my computer.  (The System Preference applicatioin is what loads the preference pains when you seledt System Preferences.)  I merely searched for "System Preferences" in spotlight.  Spotlight located 4 different versions of the System Preferences application. Some of those versions apparently tied to preference panes that used the old 32 bit encoding from the non Intel processor days.  When I clicked on the System Preferences under the Apple menue it was apparently pulling up an old version of the System Preferences applicatioin instead of the correct one in the main Applications folder.  I also noted that if I clicked on System Preferernces in the dock or directly in the the Applications folder, I would not have the problem of some of the preference panes not able to be viewed because of the " "it doesn’t work on an Intel-based Mac" message.  So I surmised that the correct System Preferences application was in the Applications Folder on the top level of the drive directory like it was supposed to be but that when I clicked on System Preferences from the Apple menue it was loading one of the 3 old System Preferences applications that were buried elsewhere on my hard drive.  If you find you have more than one System Preferences application on your hard drive you need to trash the other System Preferences Applications.  Before trashing the duplicates, you should test the one in the main Applications folder by directly double clicking it and make sure all the preference panes in it work properly then trash the duplicate System Preferences applications you found in spotlight.
         You may also find like I did, that you not only have duplicates of the System Preferences on your hard drive but also several old duplicates of the entire Applications folder buried on your hard drive. if that is the case you should compare each folder and make sure there is nothing in the old duplicate Applications folders you still need.  You will probably find that all of the latest versions of your applications are in the main Applications folder where they should be.  If so then trash all the old duplicate Applications folders as well.  Keep only the main Applications folder on the top level of the hard drive.
         Trashing all these extra old Applications folders that held old duplicates of all my applications in them on my hard drive solved a bunch of other problems I was having with some of the applications as well.
         For the technically minded:  Why does this happen with Mavericks and not with Mountain Lion?  I suspect that the old Applications folders and old duplicate System Sreferences applications didn't matter to Mountain Lion because it searched for the System Preference application under the Apple menu differently than Mavericks does.  I believe Mountain Lion seached all the top levels of the Application folder before drilling down into any subfolders to find the System Preferences application.  Mavericks apparently does it the opposite way.  It searches the first subfolder in you Applications folder and drills all the way down in that subfolder first before going to the next subfolder and drilling down in that subfolder all the way to the bottom.  So it searches all the subfolders before searching the main level of the Applications folder for System Preferences.  Since my old duplicate System Preferences applications where in subfolders with titles that were earlier in the alphabet than the main System Preferences application it searched those subfolders first, found the old System Preferences application in the those earlier folders and loaded the old System Preferences first in the subfolders instead of the correct one further on in the main Applications folder.  If any one else has a better idea let me know.

    You must be running 10.7.2 or later for iCloud.
    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s iCloud services; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
             3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
             4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
             5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
             6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
             7. Xserve (Early 2009) - Model Identifier 3,1 or later
    To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
    Are my applications compatible?
             See App Compatibility Table - RoaringApps.

  • Mac Sleep Timer (through 'Energy Saver' in System Preferences) won't work

    Hello,
    I have a MacBook (13-inch, Mid 2009) running Mac OS X Snow Leopard 10.6.3,
    and it has been installed with the latest software updates possible.
    (The latest update is the 'Security Update 2010-003')
    Previously I was using Mac OS X Leopard 10.5 on my MacBook,
    and I can vaguely remember the timed computer sleep through Energy Saver would work.
    That is, when the counter's time matches the amount of time I specified (e.g. 10 minutes), the computer enters sleep mode and displays a pulsing power light.
    After upgrading to Snow Leopard I can barely remember the scheduled computer sleep will work as I don't really notice how it sleeps / I will shut down my MacBook before I go to bed.
    ==========
    However, last night I was really tired and slept in front of my MacBook unconsciously.
    When I woke up, I found that my MacBook didn't display a pulsing power light but a continuously-growing power light.
    I tapped the trackpad and the display turned on, so I knew that my MacBook didn't go to sleep a whole night.
    *What that means is that the Sleep Timer (through 'Energy Saver' in System Preferences) won't work.*
    But the timed display sleep DOES work.
    ==========
    After spending a whole day Googling,
    I found that there are plenty of people suffering the same problem as me, although their Macs and OSs vary.
    I also found an official support page from Apple concerning the related issue:
    Mac OS X: Why your Mac might not sleep or stay in sleep mode
    http://support.apple.com/kb/HT1776
    I tried the following methods but still can't resolve the problem:
    _- boot my MacBook in safe mode_
    _- use the 'Disk Utility' to repair Disk Permissions through booting my MacBook from the Mac OS X Snow Leopard Installation DVD_
    _- reset NVRAM (Intel-based) (as PRAM is used by PowerPC-based Macs)_
    _- reset SMC (System Management Controller)_
    NONE of the above-mentioned methods can resolve the problem.
    Althought I am sure that the Spotlight isn't indexing the hard drive, and I just start my computer and do nothing and wait for the scheduled computer sleep, the scheduled computer sleep just won't work.
    In the other Mac forum, I saw someone suggest installing an application called PleaseSleep:
    http://www.dragonone.com/products/macosx/pleasesleep/
    It works.
    But I really want to find out what caused this problem as this is a function shipped with Mac which is expected to work normally.
    What's more, Apple is claiming to be a green Apple, right?

    - If I disable 'PleaseSleep' and only depend on the non-working 'Energy Saver', nothing happens.

    Looking forward to your replies! Thanks in advance!

    Found this discussion by googling "com.apple.systempreferencescouldn't find any matches"...
    One month ago I bought a brand new Macbook Pro 13", and after a couple of weeks I realized it wasn't sleeping on its own when it should, per the system preferences. (I did sleep when I chose "Sleep" in the menus or closed it... It just wouldn't sleep on its own, while open.) What was extra frustrating was that it was intermittent... It would sleep on its own maybe 1/3 of the time, but other times it would NEVER go to sleep. I deleted PowerManagement.plist, reset the SMC, etc... No luck.
    I took it to the "geniuses" at the Apple Store, and the guy took all of five minutes trying to diagnose the problem. When my MBP wouldn't sleep on its own, he promptly replaced it with a new one. That was nice, but I actually would have preferred that he diagnosed and fixed it. (I think the store was so swamped with people coming in for service that day that they were doing anything they could to close cases and get customers out of there ASAP.)
    Now, sitting here with my 48-hour-old MBP, I still have the problem. The other one was so new that I had barely put anything on it yet. The only applications I had put on it were MS Office for Mac 2011, Firefox, Chrome, and Adobe Flash Player. I've put Office and Flash Player on this one, but not yet Firefox or Chrome. That's it. No other customization or fancy business.
    I looked into the Console just now, and I see the "Couldn'tfind any matches" entry popping up again and again. The last three seemed to pop upright around the time when my MBP should have gone to sleep on its own, but not down to the second, so it's hard to definitively point at that and say it's it for sure.
    They need to fix this!!
