Help identifying cause of kernel panics

Hello, there!

I'm suffering frequent kernel panics on my mid-2010 MacBook Pro (almost every day). This is my work tool and it's become very annoying.

I have Apple Care and full back-ups on a Time Capsule so the Genius simply suggests that I do a clean install of Mountain Lion and then import all my applications, files and settings from time capsule via time machine. Still, I'd rather avoid this if I can help it, although I will admit I have never done a clean install on this machine, which is now almost three years old, so it might be a good idea. My Mac is generally a bit sluggish.

My kernel panics seem quite random, but more frequent when unplugging my external display (or upon wakeup after unplugging the external display) and sometimes when changing user account.

Below is my latest panic report and I wondered whether any knowledgeable and patient users could possibly suggest an alternative remedy. Thank you so much in advance!

I'd recommend carefully reading the XLab's article on KP's. That provides the best method of troubleshooting and possible causes. You can find it at:


I would start with your Soundflower app though, I'd recommend following the developers instructions for uninstalling and then re-installing with a version compatible with Mt. Lion.

I'd do as the Genius suggested, reinstall OSX and restore from TM.

Best to put ML on a USB flash drive first.
My iOS devices are not jailbroken.

Thank you both!

Thanks very much to both of you for replying to my message.

I've re-installed ML and so far so good, although the HD is currently being indexed and this makes it hard to gauge whether my Mac is any snappier.

Will post back here if there is anything to report.

Again, thanks very much for your advice.
