The log contains a vast amount of information, almost all of it useless for 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, 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.

If you have an account on Pastebin, please don't select Private from the Paste Exposure menu on the page, because then no one but you will be able to see it.

/var/folders/zz

Right-click or control-click the highlighted line and select

Services ▹ Open

from the contextual menu.* A folder named "zz" should open. Inside it are several subfolders, each with long name beginning in "zyx". One of them has this name:

zyxvpxvq6csfxvn_n0000000000000

Note that the name ends in a series of zeros. Leave that one alone, and move all the other subfolders of "zz" to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash.

*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.

I have a similar Issue with the "Unapproved Caller..."-error. My MBP wont start up, so i took an external drive with an older carboncopycloned version of my system an booted from that one. All works fine. I can open the problematic HD and view files. But repairing accessrights leaves a lot of stuff unsolved.

How can I find the var/folders/ directory in my problematic HD wich is not the drive from which i booted?

Thanks!
