MacBook Pro :: Snow Leopard Has A 32bit Kernel As The Default Like 64bit Kernel?
Aug 13, 2009Yes you read that right. Your brand spanking new MBP will use a 32-bit kernel as default.
You can force 64-bit kernel but some of your hardware will not be working.
So all that marketing crap about the benefits of 64-bit etc are all B.S.
I don't want a million threads about how this will not effect the running of 64 bit apps, etc. because it will. Your 64-bit app will run but it will not be able to address more than 4Gb of RAM.
There are also many more advantages to having a 64-bit kernel.
MacBook :: Kernel Panic - BAD RAM?
Nov 26, 2010For the past few days (never happened before) my apps started crashing continuously and kernel panic screen started appearing very frequently. I am still wondering what may be the cause of it, then I tested my RAM with Rember, and this log showed up:
Memtest version 4.22 (64-bit)

MacBook Air :: How Many Kernel Panics Too Much
Jan 9, 2011I 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.

Nov 29, 2009I did a quick search through the forum and didn't see anything specific about this problem. It just started to occur yesterday and nothing has changed on the computer. (Nothing new installed and no external hardware plugged in.)
Basically, it just pops up with the grey screen advising to restart. Sometimes it occurs after waking from sleep, sometimes it occurs after starting up, and sometimes it occurs in the middle of a task. I haven't noticed a specific pattern.
I ran the AHT and everything passed. I also ran Rember and the memory seemed fine in the test. I reset the PRAM and VRAM and the SMC after speaking with Apple. Finally, I reinstalled the OSX clean on the machine and the panics are still occurring.
This is the last panic report from the Macbook 1,1 2.0 with 1.25 GB RAM. I'm hoping it is the RAM and not something with the logic board, but am not sure if that can be ascertained without finding replacement RAM first.
MacBook Pro :: Kernel Panics On OS X 10.6 With 6GB RAM
Apr 3, 2010I 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?

May 22, 2012My computer had problems with display, track pad, not powering up, and lots of parts were replaced in January (MacBook Pro purchased 12.31.09). Got it home, after a while constant kernal panics. tried everything, brought it into Apple store yesterday, ran diagnostics, hard disk repaired, seemed OK.
Shortly after I came home it happened again. I repaired permissions, did verify disk, no problems with disk. Updated software, including went to Java and Adobe and updated them. Nothing works. Now the permissions note lots of problems with Remote Management (one of the updates from yesterday, 5.21) and Java (yesterday too). MacBook Pro OS X 10.6.8, would like to go to Lion but don't want to until my machine is stable?

MacBook :: Kernel Panic Upon Movement
Jan 4, 2009I'm running a PowerBook G4 and I have recently run into some problems with kernel panic. I have bought and installed new ram, zapped the pram, and re-written the hard drive and I still have problems. The weird thing is, the computer only crashes when I move it. If I just sit still then it works fine, but if I move it from my lap to a table or something like that then I get the restart message. I have an appointment with the Geek bar tomorrow

MacBook Pro :: Keep Getting Kernel Panics On New 15" I7
May 10, 2010I 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.
MacBook Pro :: Ram Related Kernel Panics On A MBP?
May 25, 2010i have a 2.2GHZ intel core duo 2007 MBP, which once ran Tiger and is now running 10.6.3I had the graphic card break down associated with such models, and it was replaced thanks to the extended care plan-I originally had 1Gig of ram, but 1st got an extra 2Gb of danelec ram, and finally another 2GB- it ran fine for a year or so-then I started getting these kernel panics, which seem to be ram related-on tiger- I changed the HDD, switched to snow leopard, and they continue, they're apparently RAM related, yet what is odd is that they can be reproduced with any RAM combination involving 2 sticks- the original apple 1Gb + any of the two GB ram sticks, the 2GB ram sticks together-- it's all the same, the screen goes grey and i'm told to shut down the computer
with one ram stick it works, apprently avoiding the issue-i've moved the ram around, checked the slots, reset the PRAM,yet the issue is still there.now i know that I should be using paired ram, and will do so in the next coming months when I can afford it- yet what has happened to make the make the MBP seemingly refuse two sticks of RAM when it didn't before ?I'd also need to know that this is not a logicboard issue if it's possible- the logic board was changed due to the NVDIA bug, so it's a year old or so-I'm running it on the 2GB danelec as I type, no issue, the samsung ram works as well, and so does the 1GB apple ram, in any slot, yet two slots of ram causes the kernel panic crash- the area near the ram slot also seems to get very hot
MacBook Pro :: Why Does Kernel Task Take Up So Much Memory
Feb 19, 2012My computer keeps freezing and applications keep shutting down unexpectantly. So when I went into the activity monitor I saw that Kernal_task and inkjet1 seem to be taking up the most CPU, threads, and memory. What are they? How can I make my computer more efficient? Are these processess causing my computer to be so slow and freezy?

MacBook Pro :: Recurring The Kernel Panic?
May 8, 2012I've been experiencing recurring kernel panics for at least a month now and I seem to have narrowed down the issue to the RAM. Now I'm just not sure whether it's corrupt kernel files associated with the RAM or the actual hardware itself. I've run the extended apple hardware test and the error message I recieve (within 5 seconds) is that the error is with the file 4MEM/1/40000000:0x84938218 I've downloaded memtest and run that within terminal. Funny thing about that is as soon as I type "memtest all" my macbook kernel panics almost immediately. Something about the "memory lock-up" phase".
Other than that my computer works fine as long as I don't run too many applications at once. Often times video streaming or opening too many tabs in a web browser will do it. And you can forget about running games that will kernel panic almost immediately. here's an example of the logs I've been getting. It's not the most recent but they all say the same thing-I've checked. Interval Since Last Panic Report:

MacBook Pro :: Kernel Panic On 2012?
Jun 14, 2012I recently purchased a mid-2012 MacBook Pro (15-inch, 2.3 GHz, non-retina) and I have been receiving Kernel Panic error messages. The screen goes black with white text in multiple languages warning me to shut down my computer and the computer freezes. I have called Apple customer service multiple times. We tried multiple things, including wipe the hard drive and reinstall OS X Lion, but I still get Kernel Panics. One thing I did notice in the "send to Apple" report is that it mentions Google Chrome. It seems whenever I do get a Kernel Panic I am using Chrome. Here are the applications I have installed (besides the default Apple ones):Coda 2Final Cut Pro XTwitterGoogle Chrome Right now, as suggested by the second Apple associate, I uninstalled Google Chrome, to see if that was the cause. She says that it could be related to that or from a software update (which I doubt considering I have yet to install any updates since I reinstalled Lion).

OS X :: Kernel Panics And Random Crashes On 09 Macbook Pro?
Nov 13, 2009I got a new macbook pro a week ago. The first time I shut the machine down it experienced a kernel panic right after I selected to shut down the computer. Programs randomly crash while I am using the computer. The apple store said that crashes are most likely due to CS3 because it was not properly updated for the system, so they installed the CS3 updates. The next time I used the machine after installing CS3 updates, it experienced another kernel panic upon shut down. I would like to hear about known issues with the Summer 09 macbooks. I am trying to determine if this is a hardware, software, or an OS issue.
View 1 Replies View RelatedOS X :: Unable To Understanding Kernel Panic On Macbook?
Oct 15, 2010I have read a million different posts, forums and most places people wouldn't want to go. This Mac is being very stubborn.
I have tried booting to safe mode, running the install disk, tried to load the utility on the install disk even tried a copy of diskwarrior (but I am not sure if it was a bootable copy).
In almost every instance the machine tries to load the cd and then spits it out and I get the restart screen. A few times I get the install to load but then it takes me to a screen that says something like �startup� run or install from these device after reboot, or something to that effect.
I even tried the command, option p r. If I just hit option with no disk it will list the mac hd. The machine is about 5 years old and is running osx 10.4.1?
This isn�t my machine so I can�t answer many questions about the OS. I was given a Snow Leopard 10.5 disk that appears to have been open.
MacBook Air :: 11" MBA Doesn't Support The 64 Bit Kernel?
Nov 13, 2010I was just playing around with my 11" MBA and found it doesn't seem to support the 64-bit OS X kernel. I tried holding the 6 and 4 keys at bootup then running 'uname -a' in the terminal and it reports I'm still running the 32-bit kernel. I also tried running "sudo systemsetup -setkernelbootarchitecture x86_64" and it reported that the architecture had successfully been changed, but on rebooting I found I was still running the 32 bit kernel.
View 20 Replies View RelatedMacBook Pro :: Using 2.2Ghz - Starts, But Then Only Kernel Panics?
Dec 11, 2010I have a 2.2Ghz Macbook Pro 15" (2007) that suddenly can't get past the startup screen and ends up with a kernel panic and the You need to restart message. Happens 100% of the time now. I had Leopard on it when it started kernel panicking. I managed to boot from an external drive and installed Snow Leopard, but it started okay once or twice, then started having the kernel panics at startup again. Tried SMC reset, but no go.
I then tried going back to Tiger, thinking it might be a problem with the RAM. Tiger actually installed okay, and after it worked okay for a bit (2-3 times, maybe half an hour), I tried to install Leopard again. And got only kernel panics. And I can't install Tiger now either.
It occasionally starts up from an external disk that I use for installs (has Leopard and Snow Leopard on it), but that's not 100%. And I can't even get thru an install now. I started up with it in Firewire Disk mode, wiped the drive and cloned a system from my iMac, but even though it seemed to go okay, when I shut it all down and tried to restart the Macbook Pro, I got another kernel panic. Any ideas? I've switched 3-4 different RAM modules, and I don't think they're ALL bad. But no go. I've changed hard drives too.
Seems weird. I mean, it doesn't seem broken, as it starts up, goes thru the startup screen, seems to pause a bit and, instead of going to login, stops with a kernel panic. I assume it's HARDWARE, not software. But hardware problems are usually the RAM, sometimes the hard disk; and if the MBPro doesn't start up at all, then the logic board is probably fried. So what else can cause these kernel panics? A bad keyboard/trackpad (top case)? Bad PRAM battery?
