Q: system preferences is not working after El Capitan upgrade

Launch the Console 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 and start typing the name.

The title of the Console window should be All Messages. If it isn't, select

          SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

          View ▹ Show Log List

from the menu bar at the top of the screen.

Click the Clear Display icon in the toolbar. Then take an action that isn't working the way you expect. Select any lines that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name or email address, may appear in the log. Anonymize before posting.

When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

Hello, Linc, I hope it is okay that I join this discussion. I am having a similar problem. Here is the information you requested for my particular version. I apologize if I have included too many lines of text.

Thank you.

I have also done the following: 1) Tried accessing system preferences from a guest user account (it works); 2) Tried starting in safe mode and accessing system preferences through my primary user account (it doesn't work); 3) tried accessing system preferences after rebooting after starting in safe mode in my primary user account (it doesn't work) and 4) checking to see if 32-bit is checked (it isn't).

I have the same problem as ialbondo -- System Prefs crashes immediately and it says "System Preferences quit unexpectedly while using the FaceCore plugin."

Here are the lines of text you requested. Thanks for any help you can give!
