    How Restore Deleted or Missing OS X Components


    A few of the basic OS X installed applications can be restored from the Optional Installs installer located in the Optional installs folder on your Installer DVD.  However, if what you need is not there then follow the instructions below.


    How to Use Pacifist to Restore Deleted or Missing OS X Components


    Insert the OS X Installer DVD into the optical drive.  Use a simple utility like TinkerTool to toggle invisibility so you can see invisible items.  Alternatively, open the Terminal application in your Utilities folder and at the prompt enter the following:


    defaults write AppleShowAllFiles Yes


    Press RETURN.


    To turn off the display of invisible files repeat the above command substituting No for Yes.


    The install packages are located in the /System/Installation/ folder on the DVD.


    Download the shareware utility Pacifist. Use it to extract a fresh copy of the missing item(s) from the file archives on your OS X installation DVD. The file archives are in the /System/Installations/ folder (use Go to Folder option in the Go menu of the Finder.)


    Here are Four Basic ways to use Pacifist (courtesy of George Orville.)


    1. Drag a .pkg icon onto the Pacifist window .....proceed to step 7.
    2. Click on “Open Package ....” and navigate to package desired and click “Open” in the open/save window.....proceed to step 7.
    3. Insert Mac OS X installer CD and when it mounts, navigate to .... Menu->Go->Go to Folder. In the path field enter or paste ....

    /Volumes/disc name/System/Installation/Packages (where disc name is the name of the CD/DVD that you inserted.)


    Click on the  "Go" button ..... • Drag a .pkg to Pacifist..... proceed to step 7.


    The package you'll need will have to be discovered by trial and error, but for most applications you should start with the Essentials.pkg and/or Additional Essentials.pkg.


    D. Insert your Mac OS X install disk 1 .... and open Pacifist.


    1.          In Pacifist, select "Open Mac OS X Install Packages" ... dialog may appear asking for disk 2, then disk 3 and finally disk 1 again.... {if DVD is not used)...If “Stop Loading” is selected...the procedure will stop!!!


    2a. When loading is complete, a new window appears, click the triangle to display contents of each package...Select item and proceed to step 7.


    2b.          or click the “Find” icon in the Pacifist window and type the name of the software you need.


    3.          In the list that comes back, click the top most entry for the item that you want. ..... that is the one for the English language.


    4.          On the top of the Pacifist window, click “verify” .... you will probably be prompted for your password.


    5.          Enter checks for.... “verify permissions” and “verify file contents.” and click “verify” ....enter password when prompted.... you will get back output which may look like this:


              20 files were scanned. 20 of 20 files were present on the hard disk. 0 of 20 files had file permissions that did not match those specified in the package. 0 of 20 files had checksums that did not match those specified in the package.


    6.          Click “close”. Go to step 7.


    Extract or Install........


    7.          In the Toolbar (upper left), you now have the option to extract or install. Click a file in the lower list and those two icons will be enabled.


    8.          If “Extract to...” is selected.... navigate to the location where the file will be placed, select “choose”, select “extract” in new dialog that appears,authenicate , if prompted, click “OK”.


    9.          In the next dialog, click “Extract”.


    10.          If “Install” is selected... dialog will appear with the location/path of the installed software. Click “Install”


    11.          Type in your password, click “OK”


    Pacifist will begin to extract files.


    12.          In steps 8/10ß.... you also have the choice to “cancel”


    Notes:          Pacifist may find that a file it is installing already exists on the hard disk. Pacifist will present you with an alert panel....


    • Stop
    • Leave original alone
    • Update .....
    • Default selection
    • Replace .... (Replace option should only be used on full install packages)

    Do you still have this problem?  I've run into a similar problem with some in-house software and although I wasn't able to figure out the root cause, I did figure out a workaround: copy the application to another location, then copy it back.  Something about this process fixed the issue for me.  I also saw a "move" of the broken application to a new location and back fix the issue on one machine, but it didn't work for another, where I think the copy operation has worked every time to fix this for me.  I think it's some kind of file attribute problem but it's not permissions or file ownership as far as I can tell.

    Lets do it the easy way.



    Three steps, stop if your problem is fixed or you get a warning the drive cannot be repaired.


    1: Hold c and boot off the 10.6 disk and under the Utilities Menu > Disk Utility > Repair Disk (if not worked, please backup and notify us) and Repair Permissions (ignore long output)


    See if that fixes your issue.




    2: You might have a corrupt SystemPrefernces.plist file in your Users/Library/Preferences folder


    Take this file out of your folder and place it on the Desktop, reboot the machine and open System Preferences and see if that works.


    If your problem is resolved, simply reset your System Preferences and delete the file on the Desktop, it was already rebuilt in the Users/Library/Preferences automatically when you rebooted and relaunched System Preferences.



    Still didn't work?



    3: You need to make a copy of your personal data onto a external drive (not TimeMachine) and disconnect all drives.


    Get out your 10.6 install disk and hold c key down while rebooting, this will boot from the disk.


    Second screen in, simply install OS X 10.6, this will overwrite your installed copy and bundled programs like System Preferences, reboot and use Software update to get to 10.6.8


    Next go repeat steps in #1 to fix a 10.6.8 drive issue caused by this update (why I don't know)


    This last #3 step will not delete your personal data (backup anyway) but some third party programs that have installed kext files may not function anymore, simply reinstall these programs from fresh sources.



    These should fix your issue, but just in case.



    4: If the issue remains, you have a problem located in your particular User (which doesn't get reinstalled from the 10.6 disk), create another Admin User account in System Preferences >Accounts and see if the problem remains, likely not.


    So you might have to use the Shared folder on the "/" root level to transfer your personal files into other account and use that, deleting the old one eventually as it s corrupted or something unexplained.



    Good Luck
