Q: coresymbolicationd: whazzup?

This procedure is a diagnostic test. It makes no changes to your data.

Please triple-click anywhere in the line below on this page to select it:

ls -@Oaen /S*/*/Caches | pbcopy

Copy the selected text to the Clipboard by pressing the key combination command-C.

Launch the built-in Terminal 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.

Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.

Wait for a new line ending in a dollar sign ($) to appear below what you entered.

The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.

The Terminal window doesn't show the output. Please don't copy anything from there.

If any personal information appears in the output, anonymize before posting, but don’t remove the context.

It means that the OS X installation is corrupt. Have you modified any built-in configuration files?

I'm trying to understand how this could have happened. Please triple-click anywhere in the line below on this page to select it:

/System/Library/Sandbox/rootless.conf

Right-click or control-click the line and select

          Services ▹ Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with a file selected. Drag the file onto the TextEdit icon in the Dock or in the Applications folder to open it. Post the text in the window that opens.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select

           Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

That's what it should be, but something else is wrong. Do you have an external storage device you can boot from?

Boot from the external drive. Navigate in the Finder to the System folder at the top level of the internal drive—not the one you're booted from. Inside it is a subfolder named "Library." Inside that is a subfolder named "Caches." Drag the Caches folder to the Trash and empty. Then start from the internal drive as usual. The Caches folder should be recreated automatically, hopefully without the corruption it has now.

1. So far we've been talking about log messages. What functional problem do you have, if any? Log messages are not a problem in themselves.

2. Do you get the same log messages when booted from the external drive? Do you also have the same functional problem then, if there is one?

I have a similar problem but am loath to reinstall the entire system.

I'm getting this over and over again in the console:

/System/Library/Caches/com.apple.coresymbolicationd does not exist. Could I just re-create that directory and then maybe it could write?
