Kernel panics on Mountain Lion are normal?

I made the mistake of upgrading my Mac Pro to Mountain Lion. Since then, I've been plagued by several nasty issues. They are:



  • 4 to 5 kernel panics per day now on average. In the previous 4 years of owning this machine, I'd only seen one total before Mountain Lion.
  • Preferences are not being retained when saved. This is especially maddening in Mail where I have to correct a mail setting every single time it launches (or restarts from a hard freeze/kernel panic)
  • Whenever a kernel panic happens, the contents of my two monitors are swapped. What is supposed to display on the left display jumps to the right display and the contents of the right display move to the left display. This includes menubar, desktop images and my geektool scripts.
  • While not technically a bug, I feel completely mislead by Apple regarding Airplay capabilities. I upgraded solely for this one feature only to learn that my 8-core, 12Gb of RAM, Dual Video Cards and SSD Raid is not sufficient to utilize this feature. This is incredibly dishonest marketing on Apple's part.


Any suggestions on how to proceed? I'm leaning towards reverting back to Lion and askin

Hey there,


I'm on a MacBook Pro3,1 and had persistent kernel panics since ML update. Suspects were the Nvidia bug which my machine is known for, several third party stuff including parallels, hardware issues, and so on.

Crashes went on even after a clean install on a formatted disk.


Updating Nvidia cuda drivers here:

seems to do the trick for me.


Did not have crashes since I installed this.


Hope it helps at least a few people.


regards,

Hi HoffMan (and anyone else with the same problem).


I took all the steps you did to try to fix this problem and tried updating my Nvidia drivers, but they would not install on my machine. Took my macbook to the Apple Store to run a diagnostic and it came up with a hardware failure on the graphic card. My macbook is 2 years old and I don't have Apple Care so its out of warranty. However, they informed me there's a "known" problem with some Nvidia graphics cards that shipped with my machine and if less than 4 years old Nvidia cover the cost of replacement - in my case they replaced the whole logic board. I have been running without problems for a week since. I would suggest you try this before downgrading as you may have problems with it in the future.


Hope that helps.


regards,

MD

Kernel panics are NOT normal - they are always a symptom of something wrong.


Millions of Mountain Lion users are NOT experiencing them, so it is still more likely that it is something with your machine - it could be software related.

But it could also be some hardware component that simply went bad - RAM being the most likely. If you can, run a hardware test (restart and immediately hold the D key). There are also third party utilities that can test your ram. Look up the web for "memtest".

I can totally understand your frustrations, as I have had simialar issues! What is even more annoying is after getting a supposedily genuinly concearned phone call from AppleCare Customer Services, I was told that I would recieve a follow up call and if I had any queries too email the customer rep. After weeks of not hearing back from the customer reps I emailed the rep and after 4months and guess what no reply. Even calling Applecare they tried contacting the rep. I guess Apple's new attitude since Steve is no longer around is we will take your money employ incompetant software engineers and basically "who gives a rats a?? about the customer" as it sure certainly seems that way no matter how you look at things... Thanks Apple and Apple Care for caring NOT!

I just had another kernel panic and thought I'd share a few other things I've noticed in the moments before a kernel panic happens. To be clear, I'm having the kernel panics with particular extensions com.apple.NVDAResman, com.apple.GeForce, and com.apple.iokit always showing up in the problem report.


A few things I've noticed:

• When my machine seems to be prone to a kp, Silverlight will have crashed. Chrome explicity says as much when I try to watch something from netflix (silverlight-based).

• When watching video content on Hulu, using the full-size video feature produces choppy and extremely low fps performace implying that graphics acceleration is not taking place.

• All of my kernel panics occur with some sort of video activity playing. It's not just silverlight, but html5-based videos and flash has triggered the kernel panic.


Anyway, best of luck to everyone suffering the same issue. I'm hoping for a graphics update to ML but Apple's response doesn't give me hope at the moment either.

My iMac i7 27 inch was running fine on Lion, well, almost. I had to call tech support once about kernalP crashes and they kind of fixed it using Disk Utility. That said, as soon as I installed Mountain Lion, the KernalP crashes began coming fast and furious. I did a clean install of ML and within 1/2 an hour another KP crash occurred, so I took the machine back to the store. There were two other customers clutching their iMacs saying the same thing had happened to them. What the **** is going on with Apple that when you buy a new iMac with their latest software and you can't even rely on it for more than a few months, especially considering that the previous model ran flawlessly for 2 years on Leopard and Snow Leapard?

Kernel panics on Mountain Lion are normal?
