OS X :: Frequent Kernel Panics When Playing Games

Nov 21, 2010

As the topic suggests I keep getting kernel panics when playing games on the 9600 m GT (it never happens on the 9400 m). I never have kernel panics when playing left 4 dead 2, but I get them playing left 4 dead 1 and games like WoW and Age of Empires 3. Here is my crash report, and I don't game in bootcamp. Running 10.6.5 on a late 2008 unibody macbook pro. Can anyone tell me from the crash report what's going on?

OS X :: Constant Kernel Panics On IMac

Apr 10, 2009

My computer is having constant kernel panics. I have had about 10 in the past 18 hours, and I am starting to freak out about it. Here is the info from the error report:

BSD process name corresponding to current thread: firefox-bin
Mac OS version:
Kernel version:
Darwin Kernel Version 9.6.0: Mon Nov 24 17:37:00 PST 2008; root:xnu-1228.9.59~1/RELEASE_I386
System model name: iMac5,1 (Mac-F42786A9)

The part that says BSD process name corresponding to current thread has changed every time. When I have apps open, it will read the name of the apps extension but if I don't run anything it will say "system kernel" or something.

PowerPC :: IMac G4 Kernel Panics - Overheating?

Aug 9, 2007

Yesterday a friend gave me a really nice 17" iMac G4 he was planning to throw out because it was having problems. I would really like to get this working and would potentially be willing to buy parts to repair it. I have a significant amount of Apple hardware experience, but would like to get the opinions of people who may be more familiar with iMacs than myself on these forums. The problem is that the computer has random kernel panics. Sometimes it occurs as soon as the computer is turned on, sometimes after it has been on for a few minutes, sometimes after a few hours. So far, I have replaced the RAM with known good sticks, have replaced the hard drive with a tested good one from my collection (and these were both upgrades to boot!) and I have re-applied thermal paste (Arctic Silver) to all key components (CPU, ends of heatpipe, GPU) but to no avail, I still have the same problem.

IMac :: Getting Kernel Panics - Freezing / Locking

Jul 14, 2009

Our 1st gen 24" iMac was giving us Kernel Panics under Tiger 10.4.11 recently it all started two months ago. We took it into the Apple store for a Cleaning and fresh install of Leopard.
When we received it back it locked/froze up immediately, forcing a hard restart. When I called the store they said one of my sticks of ram was not techinically bad but still suspect. This is what I did after that call.

1. Checked the ram physically (the Apple store had placed my 512mb Apple ram stick in slot 0) which I thought very strange.
2. I corrected the ram, meaning I put the 2gb (suspect) stick in slot 0 and the 512 Apple ram in slot 1. Things were better it would take 10-15 minutes of use before locking up not 1-2 minutes.
3. I placed a new stick of Crucial (2gb from OWC) in place of the supect stick. that has had ZERO affect, our mac still freezes.
4. I pulled out the 512mb Apple (Micron) ram and replaced it with a 1gb Micron stick from OWC and that gives us roughly 20-40 minutes of time befroe freezing.

The software is up to date, I've max'd out the ram (new ram per Apple's request) and all we have running is iTunes in the background to stream to AppleTV and a few tabs of Safari open when this locks up. Right before it freezes we notice lines arcoss the application windows almost as though there a distorted pixels. When we took it in (running Tiger) the Apple Tech did check the drive and boot from their network and said our HD was not the issue, but it wasn't up long enough to cause kernel panic.

IMac :: Strange Noise And Occasional Kernel Panics

Sep 30, 2010

I have a 24" iMac which is just over 12 months old. I noticed recently that occasionally the iMac emits a short burst of grey noise, a sort of hissing which distorts whatever sound is being emitted at the time, (music or whatever). This happens at no particular time and when running no particular program. I have tested it with external speakers and also headphones to confirm that it is not the built in speakers that are causing the problem. The sound burst usually lasts just a couple of seconds. It is not particularly loud and is something I can live with. Also recently the same machine has suffered from occasional kernel panics. Usually after being on for some time. Again at no particular time or process. If I restart the computer it often panics again.

IMac :: Pixelated Screen At Login And Kernel Panics

Oct 14, 2010

Got the iMac 27" Late 2009 (bought it when it came out). Its always had the 'pixelated' issue (see attachment) just before the login screen appears but I've never bothered too much as its not been a problem, until recently where I am getting a lot of 'Kernel Panics' (screen wipes down and locks done entirely, have to restart to get the system up and running again). I am starting to think that the screen issue is finally starting to shows its true colours. Yes, I've done the PRAM resets, disk repairs, up-to-date with all the software etc. No joy.

OS X :: Kernel Panics On IMac - Boots Only To Safe Mode

Nov 12, 2010

I have a feeling I need a new motherboard to replace my graphics chip. I was playing World of Warcraft last night when the entire computer froze and a pink grid came over the computer. Could not force quit. About 10 seconds later, Kernel Panic screen and I have to hard reboot. Every time I reboot the pink grid is still there and it kernel panics, does not get past the spinning Apple logo. I was able to hold down shift and get it to safe mode, and was able to back up my files that way. I also ran the Apple hardware test, but it said no problems found. I am typing to you now in safe mode on this pink screen.

Hardware :: Imac G5 Applications Quitting And Kernel Panics?

Apr 14, 2009

I purchased an imac g5 on ebay about 2 months ago. She said it's an older computer that is in good working condition except it may need restarted a few times every now and then. Everything worked fine for the first few weeks.. but now when I try to power it up it makes a loud crackling noise and freezes. After about 5 or 6 times of restarting it I can finally get it to start up correctly. But then my applications quit unexpectedly all the time.. especially safari.. and illustrator and indesign a lot too. I ran the extended hardware test and it fails on the memory.

OS X :: How To Log Kernel Panics Automatically On 10.6.5

Nov 18, 2010

I tried to locate /Library/Logs/PanicReporter according to this link to no avail. I'm not happy with logging using verbose mode and having to retype it all up. I also don't have it in a network of macs to allow for this technique and I feel as if there's a pretty obvious way of capturing these reports that I'm missing.

MacBook Air :: How Many Kernel Panics Too Much

Jan 9, 2011

I have had the Macbook air 11.6 for five weeks now and it has been rock solid except for a couple of kernel panics. Once when I first got it I got a kernel panic in Safari. I only use google browser now. I got a kernel panic two days ago. I went to open the lid and it did not come on. I found out there was a kernel panic. I am afraid if I take it to the genius bar they will have me reinstall the OS and add one app back at a time to see what is causing it but since they are so infrequent this is obviously not convenient. Also I have had my IMac 24 for three years and have tons more junk on it and have never got one panic.

OS X :: Kernel Panics On Two Machines?

Sep 8, 2009

Can kernel panics on one machine somehow cause panics on another machine. My situation, I recently started using a BC338 esata card in my mid 2007 MBP running Leopard. Never had panics before but since trying to use this card with an esata drive I've had 5 kernel panics. I also have a Mac Mini running Snow Leopard which has had two kernel panics during times when the MBP had panics. Can these be related? Before using this card, I never had panics on either machine?

MacBook Pro :: Kernel Panics On OS X 10.6 With 6GB RAM

Apr 3, 2010

I am currently planning to upgrade my 2gb RAM and I heard that my model supports up to 6GB of RAM, hence I am planning to upgrade to that size cause Aperture uses lots of memory and I use Aperture a lot. I am planning to get it from here: OWC 6GB PC5300 DDR2 667MHz DIMM Upgrade Kit. Everything is cool and all until I find out that some users are having kernel panics on OSX 10.6 with 6GB RAM (which is what I am using). It is now 10.6.3, so anyone care to report if it is safe to use 6GB or the problem still exist?

OS X :: Kernel Panics After Sleep?

Apr 20, 2010

I've been having a lot of Kernel Panics (you need to restart black screens). I've only just worked out that they almost always occur after the mac has been dormant. For instance, I'll leave the machine on (and the black screen/sleep mode activates instantly), after twenty minutes I come back to the machine, it comes back to life, but within a minute or so it crashes. This seems to be the pattern, it very rarely crashes mid-use. Safari is also nearly always loaded?

OS X V10.7 Lion :: Kernel Panics In 10.7.4

May 10, 2012

I kid you not,  ever since I updated 10.7.4 last night, I've had at least 3 kernel panics, plus it wouldn't wake up from sleep. 

Sometimes it seems to crash for no reason at all -- the computer will just be sitting there and I won't be doing anything; granted, I'm sure a skillion processes are running, but no more than I would usually run. 

Where are the pertinent logs hiding so I can share them with some wise soul?

Power Mac G5 :: Booting Up And Kernel Panics

Oct 10, 2007

Last week, after completely normal use, the computer booted up to a screen with the finder icon / flashing question mark. After a few more atempts to power up i started getting just the grey apple screen with spinning wheel and loud fans. I was advised by a friend to boot from the install DVD by holding alt when powering up. When i try this, after selecting the DVD from the boot up options, I get kernel panic and the message " panic: We are hanging here...". Then nothing.

Mac Pro :: Getting Kernel Panics When Monitors Connected

Apr 8, 2008

I've been using my new Mac Pro with no issues for several weeks with the same hardware setup & OS all along. Suddenly I'm getting kernel panics. It happens when I startup from the system drive or from install disc. And sometimes when I startup it just hangs on the blue screen with no desktop coming onto the screen. It started happening after I did a Carbon Copy Clone of my system drive onto a firewire drive, & when I came back to my computer several hours later the screen was black & white stripes. I've been on the phone with apple care several times and even took my machine to the genius bar today where they recommended a stress test and said I would get it back in 5 - 10 business days (gasp!). Of course there were no kernel panics while I was there (for an hour, and at home I'm getting them every few minutes), so I decided to take it home & check it over myself in a process of elimination.

I've removed all third party ram, and have 2 hard drives installed - the system drive & the drive I use for time machine. The RAM is listed as OK in system profiler and the HD's are verified with Disk Utility - also disk permissions verified & repaired on the system drive. I have 2 Acer monitors - model AL2016W. I tried plugging in one at a time in each DVI port for a total of 4 tests - each with a fresh startup. There were no kernel panics. Then I plugged them both in at the same time, started up, & got the kernel panics. Tried this twice with the same results. With or without any applications open, it's the same. Within 2 - 4 minutes I get a kernel panic when both monitors are plugged in. Later, I got kernel panics with just one monitor connected. So my question is; What could be the reason it's getting kernel panics sometimes & sometimes not? As I said, nothing has changed in my setup since I got the machine - and everything was running fine since mid February.

During my testing I have these connections:
One or two monitors. Power cord. Apple wired keyboard & mouse (these were not connected at the time this started happening so I have eliminated them from the possible source of trouble.) All bluetooth devices are powered off & no other external devices are connected. I just completed the Apple Hardware Test & it detected this error: "4HDD/11/40000004.SATA(0,0)" Does this mean there's something wrong with a hard drive? If so, which one?

Mac Pro Early 2008 2.8 Mhz 8 core
OS X 10.5.1
2 gigs original "apple" RAM
HD 1 - Samsung F1 (system - 750 gigs of which 420 are being used)
HD 2 - Hitachi (time machine - 1 TB)

OS X :: Getting Kernel Panics When USB Hubs Plugged In?

Feb 10, 2009

I have become increasingly frustrated and angry at my MacBook in the last few weeks. Nearly every time I plug in a USB hub, I get a kernel panic. When I send the report to apple, this is what comes up near the bottom of the window:

Backtrace continues...
Kernel loadable modules in backtrace (with dependencies):

Sometimes there's a USB HUB written in there. What is going on? I've tried switching from a rather generic hub to a Belkin one, and most recently I just plugged in my aluminum keyboard and immediately got a KP. They've been happening with regularity over the past while, all when I unplug or plugin my USB hub with an iPod touch, keyboard/mouse, USB drive and headset (though recently I've been removing peripherals). I'm about to do an archive and install (assuming my MB works long enough for me to download the combo updater) but want to kill this bug soon.

Mac Pro :: Repeated Kernel Panics / How To Avoid It

Feb 20, 2009

I began having freezes unrelated to any new software or behaviors. The hardware check showed no problems with the hardware or memory, so I cleaned out the inside of the computer, used Disk utility, AppleJack, Mac Janitor and reset p ram (all said it was OK, then the freeze came back), and finally zeroed the hard drive and reinstalled OSX.

It was stable for a few weeks then the freeze happened again followed by repeated kernel panics. I went thru all the steps above again but finished with an archive and install and created a new user admin account. Until this point the freezes and KP were on all three user profiles. But now this new user admin is fully functional while the others are still messed up.

OS X :: Having Huge Number Of Kernel Panics

Feb 24, 2009

New to the forum and unfortunately with a problem. Just got a new Mac Pro 8 Core over the weekend and Im having unusually high number of Kernel Panics (more in a couple of days then I have for the past 10 years with my other macs). I have tried to see if anything in particular causes it (ie Programs that cause the crash, time intervals, etc) and nothing can be ruled as the cause at least not that I can notice. It has happened wile using PS (CS4), Aperture, Google Earth, Safari and just in sleep mode. Here is one of the Kernel Panics along with system info. ps. The Mac started kernel panics before I loaded two additional hard drives and the wireless card (pci express).

PowerPC :: G5 Having Kernel Panics 3 To 4 Times A Day

Jul 24, 2009

The computer I am having problems with is a Mac Dual 2.7 Ghz Power PC G5 with 3.75 GB DDR SDRAM. Moved premises at start of year - had to have a new ethernet adapter card fitted but no problems for about 4 months. Then it started having Kernel Panics. It got to the stage where at one time it was 3 to 4 times a day. Took it to a local repair shop who put it on test but said they couldn't find a problem. Within 10 minutes of my switching it on it went again. They changed a memory board. Still no change. Changed Ethernet adapter card. Still no change. I have a print out of the latest system & console logs I can email if that will help an expert.

After some partition troubles I popped in my snow leopard disc and erased my HD. I then made a windows partition. Then, I tried to restore from a time machine back up I had. It finished restoring and said to restart, so I did. It doesn't get past the apple sign though. After the grey screen with and apple logo sit their for a few seconds it kernal panics. I can't get any farther than that. Should I re-restore or what?

MacBook Pro :: Keep Getting Kernel Panics On New 15" I7

May 10, 2010

I got a new 15" i7 MBP w/7200 RPM and hi-res anti-glare last Thursday and since then I've had a number of kernel panics, three today

Any suggestions on what it could be or what I should do?

From the looks of it it has something to do with the graphics card, maybe the auto switching feature.
