Apple Error Codes
Hi and Welcome
Well, if it happens when you open System Preferences, obviously something is corrupted with your preferences. Have you recently installed any new software, especially one that installed a new Preference Pane? If so, try uninstalling it. If you log in with a test or other user account, do you still have the problem?
According to Apple Error Codes here: http://docs.info.apple.com/article.html?artnum=9804
That error code means, “no eligible process with specified process serial number”. Are you by chance using an application that was a trial version and it expired?
Also, anytime you get the, “application unexpedtedly quit” dialog box, it can also mean there isn’t enough available disk space. Open Disk Utility from the Applications/Utilities folder. Select MacintoshHD in the panel on the left. Now look down at the bottom of that window where it says:
Capacity and Available. Make sure you always have 20% free disk space of the total drive. It takes 15% just to boot your Mac.
The issue may also be related to some kind of directory corruption. So, what do you do? Usually when apps start crashing unexpectedly the first step is to delete the preference file for the offending app. The preference file look like this, apple.com.iphoto.plist. All the preference files are in the same pattern, it’s only the name of the app that changes. You’ll find them at
Also give try to:
Open a Finder window and type, apple.com.safari.plist into the search box (top right hand corner of the window). You will see the file in the window. Drag it to the trash, empty the trash and restart your computer. Safari should start with a new preference file. If it starts go straight to titanium software and download Onyx.
Also, to find the preference files you want you can extend the size of the actual column (in column view) so you can see the full name of the files.
Finally, do you have the original install discs for your Mac? If so, you should start the computer by booting from the disc and run the disc repair utility. This may fix it.
Here’s how: Insert the OS disc and shutdown the computer. Next, restart the computer holding down the ‘C’ key. This will make the computer boot from the CD. When it starts go to the file menu and open the disc utility. Select the hard drive in the left column and then repair disc. – If the installer starts just quit it.
Give them all a go. I look forward to hearing some positive results.
