Itunes update, panic debugger

If you can't boot in the usual way, try a safe boot.

During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. If you have more than one user account, you must be logged in as an administrator to carry out these instructions.

Safe mode is slower than normal, and some things won’t work at all.

Note: If FileVault is enabled on some models, or if a firmware password is set, or if the startup volume is on a software RAID, you can’t boot in safe mode.

If you're able to boot, 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. Click Utilities, then Console in the icon grid.

Select the most recent panic log under the heading System Diagnostic Reports on the left. If you don't see that heading, select

View ▹ Show Log List

from the menu bar. Post the entire contents of the panic report — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post shutdownStall, spin, or hang reports.

If possible, take a photograph of the panic screen and post it here. The text on the screen has to be readable.

If you don't already have a current backup, back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.

There are ways to back up a computer that isn't fully functional. Ask if you need guidance.

If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

There are several ways to back up a Mac that is not fully functional. You need an external hard drive to hold the backup data.

1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”

2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.

3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Bumping this thread. I've got the exact same problem, exact same error being thrown but on a macbook air. Update is to 10.8.5

Had to boot into a live linux distro (I used ubuntu) to grab my files that weren't backed up. Ran through the logs to try and pinpoint something but came up dry. Restored by booting from my external drive that contained time machine backups. Removed all third party extensions and anything I thought could be underlying this issue. Problem is, I have no idea what that could be.

Ran the update again and hit the same issue.

I don't have a copy of Mountain Lion for a clean install, as this was purchased in store and didn't come with the DVD.

What are my options besides driving 2 hours away to a major city and giving it to the teenage shmuck bar?

bnegley,

Did you run the 10.8.5 update succesfully on that that computer?
