I have a MacBook Pro (MacBookPro6,2) running OS X 10.7.5.

Once every few days, on average, my screen goes black and it stops responding. Before these incidents I'm mainly browsing, random web pages with Google Chrome.

The keyboard remains lit but no sounds, no response to the keyboard, etc.… I have to force a shut down (press and hold the power button) to get it going again, and when I do, I am presented with an problem report dialog (kernel panic details below).

Might it be an NVIDIA problem?

What can I do about this?

    Is there a specific application your running when this error occurs or is it at random?

    mainly just random web browsing, most of the time (using Chrome)

Looks like it might be the ram or graphics card.

First, you should do the Apple Hardware Test and check your hardware out for any issues. Press and hold the D key before the gray startup screen appears. (On some versions it is Command + D)

Next, I would look into this forum thread because most of the users have a similar error. Some report that its a setting that can be changed and others report that apple has replaced all their hardware with the AppleCare Plan.

Good Luck.

For grins, if it happens every few days only, why don't you shutdown your laptop each night and start it up each morning?

  • Thanks for the ideas, I will have a go at that. I really hope its not hardware, big inconvenience...

  • These are sometimes tricky. Maybe try a different VM host like VMware Fusion for your guests?

  • just an update, I have switched to the integrated graphics, and so far no crashes...

Google Chrome

At least one version of Google Chrome is known to cause kernel panics on OS X. Amongst open issues for Chromium there are currently nine matches for panic NVIDIA and one match for panic NVDA. At least one of the Intel-oriented titles includes discussion of kernel panics with NVIDIA hardware.


Google Chrome may report itself as current when in fact it is outdated. Today, for example, 21.0.1180.89 (stable in August 2012) is reportedly up-to-date – 

screenshot of an outdated Google Chrome with a misleading statement

– but that's not true; I download another copy from Google and find something more recent:

Finder Info for Google Chrome 23.0.1271.64


Use something other than Google Chrome to check that Google Chrome is up-to-date.

At the time of writing, Chrome Releases: Stable updates shows 23.0.1271.64 in a post on 2012-11-06.

Third party kernel extensions

In my experience, some types of unexplained panic may be avoided by paying attention to third party KEXTs.


Your installation of VirtualBox should be updated – 3.2.0 was outdated in June 2010.

Even with recent version 4.2.2 of VirtualBox, with NVIDIA hardware in a MacBookPro5,2 I sometimes find kernel panics. For these incidents, not all .panic files point to NVDA or VirtualBox but I have a strong sense that VirtualBox is at least partly contributory to the issues.

(Side note: 4.2.4 at http://www.oracle.com/technetwork/server-storage/virtualbox/downloads/index.html … I'll give that a go.)


Looks like you have a Mid 2010 15-inch MacBook Pro, just like myself.

Mid 2010 15-inch MacBooks Pro come with a defective NVIDIA GPU that may cause unexpected restarts, kernel panics, black screens See Apple's support article.


Just so everyone knows, I had to bite the bullet and take it in to be fixed, but as it turns out this was a known fault in my line of Macbook Pros (lucky me) so it was fully fixed with no cost.
