Mac Pro :: Mac Pro Won't Boot / Kernel Panic At Boot Graphics Card Failure?
Oct 2, 2009
Yesterday my screen (30" Apple Cinema) started showing symptoms of graphics card failure, jagged lines across the screen. I rebooted my Mac Pro and it was gone. Then it happened again an hour later, this time the machine didn't boot, I get the Apple logo, and then it hangs up and the screen is shifted to left (I get apple logo on left side of the monitor instead of the middle) and jagged lines all over.
So the first thing I tested was using Target Disk Mode, it works. I can access my Mac Pro's internal HD's by TDM from my MacBook Pro. Then I tested single user mode, it does boot, I can't read what's written since the screen is shifted to left, but if I type (without seeing) reboot and hit enter, it reboots. So I assume the single user mode is working.
What else can I try to 100% make sure it's my graphics card that failed and everything else is ok with Mac Pro? I already ordered a graphics card replacement but I wouldn't like to be surprised if the Mac Pro still doesn't boot when the card arrives.
P.S. It won't boot from Apple Startup DVD either. Same thing happens, gray logo then kernel panic with jagged lines all across the shifted screen.

I have an iMac that I bought in October 2007. All of a sudden, when I try to boot up my computer, I get a kernel panic. Can't get any further than the kernel panic even though I keep on re-booting.

I am a network adminstrator (for a windows network ) but personnally an Apple User. I am savy with linux and unix enough to get around etc, so my knowledge is broad and indepth.I have never had issues with my own Macs in the past 5 years, but my friends MacBook has an interesting issue.She told me that the computer was doing updates, and she didnt want to wait for it to finish and just shut it off in the middle of some OSX updates.

I moved over to an IMac from windows about 2 years ago and have never had any issues, until now. Whenever I boot my IMac I get a 'kernel panic' message (grey screen with 'you need to restart your computer in 4 languages). I cannot boot from my Mac HD, nor from a bootable superduper backup external HD, nor from my orginal SL or Leopard disk. All go into the kernel panic. I can however boot from my bootcamp Windows Vista partition. Tried booting into safe mode also does not work and gives the kernel panic screen. I have run both the standard and extended hardware tests and both have no errors. I booted in single user mode (that still works)and done a fcsk and unmount and both are without errors. Also done RAM flash. In single user modei can not find a PanicReporter directory or panic log. Cannot even install a fresh SL copy as my DVD wont boot either.

Recently my 2-year old iMac (20inch (2Ghz, 320GB, 4GB RAM, OSX Leopard) has been crashing every day. The way to temporally "fix" the kernel panic is to restart the machine and boot into the instal disc, and run the disk utility (repair permissions, then repair disk). If I do not run the disk utility daily, the computer will begin crashing again over and over. Below you'll find the the crash data (which is always the same):

I honesty don't know what to do to stop the crashing (other than runing disk utility every day). This is never happened before now.

Yesterday I was helping someone getting to know their MacBook Pro (early 2008, Intel core 2 duo 2.4GHz, Mac OS X 10.5.2). I installed Perian and Flip4Mac and Firefox 3.6. I also checked for updates because she's on a very old version. I tried downloading the updates, but because we had a very bad internet connection I stopped the download quite early on and told her to do it at home. However after I left she tried to shut down the computer but it hanged. She manually shut it down using the power button. When she tried to turn it on again she got a kernel panic message saying she should reboot. This however didn't work.
Now I've tried all sorts of things. I've removed Perian and Flip4Mac manually. I did a disk verification (all was well) and a permissions verification and repair. I tried booting in safe mode (still won't boot) clearing the SMC and resetting PRAM, none of it worked. I just wanted to check here first before either taking it to an Apple store or reinstalling Mac OS X. I've read on forums about hardware failing (RAM mostly). No idea if that's the case. I tried a hardware test, but I don't have her DVDs and used my own with version 10.5.5. The Standard test said it was all ok, but the extended test seemed to hang. I could ask for her own DVDs which I will need anyway if I'm going to reinstall Mac OS X.
Some details of the kernel panic:
The error code is: 0x000000010
Apart from that it says the following:
Backtrace terminated-invalid frame pointer 0
Kernel loadable modules in backtrace (with dependencies):
com.apple.driver.AppleIntelCPUPowerManagement(76.2.0)@0x2e63c000->0x2e65afff
And later on it says: Mac OS version: Not yet set.
And of course it shows some more info with lots of hex codes, I can type them out for you if you like, but I read elsewhere that the error message is usually not very useful. Would you recommend going to an Apple store to see if the RAM is faulty? Or do a reinstall of Mac OS X?

Ever since I've got this iMac on the office, I've got the occasional kernel panics. At first they seemed to redeem themselfs during runtime, but for a while now, they seem to pop up at boot. And I mean, even not getting the Apple logo and it already freezes. I seem to be having this problem only in a frequency of say... once in two months or so? Â
Today I got it again and it even occured two times in a row, third time the system booted up. I would like to know whats up, I figure this must be a hardware issue since the system doesn't even load up. I'm a bit worried about sending this machine for it's warranty, since I won't have a machine for like 3 weeks until it gets back...
Here's the kernel panic:Â Â

I've got a Powermac G5 desktop. I recently purchased a used keyboard for it off of Ebay. The computer was working fine with just a mouse. Shortly after the keyboard was plugged in, I got a kernel panic, and had to restart. I restarted, and immediately got a message saying "you need to restart your computer", and followed by another kernel panic.
Now, I get a kernel panic and "restart your computer" message, even if the keyboard is unplugged.
I was planning to do a clean install of OS X anyway, and figured that since the computer is completely useless at this point, now would be a pretty good time to go ahead and do it. So I tried to boot from the install CD by inserting the CD and holding down the 'C' key. No result -- it doesn't show me the "boot menu", and instead proceeds as usual, to it's "Restart your computer" message and subsequent kernel panic.
So I then tried rebooting and holding down the "Option" key, and managed to get to the boot menu. I selected "Mac OS X Install Disc 1" and clicked the "--->" button ... kernel panic again.
I'm at a complete loss for what to do next. Any help with this would be much appreciated. All I want to do is reinstall OS X.
How can there be a kernel panic from the boot CD? Apple didn't make it where it tries to use the kernel from disk during install did they?
I'm coming from a Linux background, and am not at all familiar with OS X, so forgive me if I've left information out that I should have included. Please let me know if this is the case, and I'll do what I can to provide it for you.

my name is SPC Sanders. I am a forward observer currently deployed to Afghanistan. I've owned a Macbook Pro for a couple of years.
About three weeks ago, I made the stupid mistake of attempting to run iOSX so I could dual boot with Windows 7 (all stuff I acquired while I was home on midtour leave.) The install seemed to be ok, however, I noticed immediately I could not make any changes to settings as my administrator password was no longer working. (Administrator is my only account on this laptop.)
At fear of losing my operability, I simply did not power down for that whole time. However, I recently moved bases, and alas, the time came to power down.
Upon bootup, I get a constant spinning wheel. I left this on for a couple of hours just to be sure, then realized it was a lost cause. I tried booting in safe mode, and I got some kernel panic. It says a bunch of stuff about debugger calling the panic, bla bla bla, but the thing that caught my eze was Mac OS version not set yet.
After booting in safe mode, getting that error, and powering off, my laptop will boot into a grezish blueish lightblueish (alternating) type of screen, which sometimes has the spinning wheel, sometimes not. Again, nothing.
I understand I will probably need my OS disc to fix this, but I didn't bring it with me. Am I SOL?

Mac G5 ppc OSX10.4.11
Starting up from any boot disk will give me a kernel panic forcing me to hard restart.
Background:
After many freezes I ran disk utility and I get:
Checking Catalog file.
Invalid index key
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
So I use my wife's Imac startup disk to boot it in order to repair but I get the dreadfull death screen (I know how to press the C) I'm thinking maybe it's because her disk if for her Intel proc so I go and buy a copy of disk warrior 4, and same problem.

Stupidly installed this: [URL] wanting better performance from my Nvidia 8600M GT 512Mb. Was asked to restart after install & wouldn't boot (only getting the grey then blue screen in 10.6.2) Am now unable to boot up in anything other than Safemode. While installing update is gives the option to revert, tried this in safe mode but it ends in a fail. If it can revert then somewhere is a backup of the original driver yeah? Where is it & can restore it manually/rename it as the original? Tried to use TimeMachine but won't boot for me in Safemode.

Macbook Pro won't boot. Symptoms preceding failure included failure to open Firefox. When trying to cold boot I can get as far as the start-up sound, the Apple logo, and the spinning whieel (spins for a bit but not for very long) and then major failure. Not running Liom.

I installed USB Overdrive (a program), I clicked on restart and my iMac never got up. When I start it, the HDD and fans do work. But there is no boot sound, and when I change sound levels, I cannot hear it. I think, it never makes it to OSX. It does not load the OS. I dont think it is Graphics card (HD2600) failure.
When I try to reset PRAM, nothing happens. Usually I must hear it restart again with loud boot sound but it never happens. Also my keyboard does not seem to work, as the CAPSLOCK button does not light up, when pressed. I changed RAM to different moduls, still the same. I checked the iMac RAM on a different computer, it works. Maybe USB Overdrive killed the USB slots? As my USB keyboard does not seem to work

a friend recently gave me a g5 power mac that had some issues, and the failure was described as intermittant. The machine supposedly would work properly when booted and start freezing up after time, but if turned on the next day it would work properly for some time. I assumed it was an overheating issue, but apperently there is more to the picture. I have tried booting the machine quite a few times and the display always reads no signal. The machine sounds as if it were booting normally, but there is not output. At first I assumed it was my display cable, which was a DVI-D single link, however the DVI-D dual link cable leads to the same result. Is it nessicary to have a DVI-I cable? None of the error LEDs light up on the motherboard. After doing some hunting I haven't found anyone with the same issue, but I am wondering if I should assume the graphics card is dead. What steps do I need to take to isolate a graphics card failure in a power mac g5?

The string of problems I've encountered started a few days ago. I normally let my imac go to sleep by itself but, on this occasion I told it to sleep via the apple menu. When I awoke the imac the screen was frozen. No mouse movement, no clock movement, nothing. At this point I turned the power off and back on again. It didn't get past the white screen (before the gray with apple logo). I then tried resetting the PRAM, booting in safe mode, and booting from my os disc. Nothing worked.
After several tens of tries it magically booted. It stayed active long enough for me to back up all my data (transferring at least 100GB), reformat the hdd, reinstall leapord, transfer data back, and use it until I let it sleep again.

why i have to unplug the power cable from the back of my imac after every power failure at my home to get the imac to boot up. I've tried resetting the surge protecter and unplugging there. However, the only option is to unplug the cord from the back of the monitor/imac before it will boot up.Â

Just got my new Macbook Pro Retina. Migrated my applications and data from my Macbook Air. Everything worked great. Apple Update advised that new updates were available. I accepted and ran the updates. Now it gets a kernal panic at boot. Can boot into Safe Mode however. I used Command R to reinstall OSX but that did not correct my problem. Same kernal panic persists.

I just recently started to experience some very unusual behavior on an older PowerBook G4, and I was wondering if anyone has experienced this before, as I can't seem to find any documented info on this.Basically, out of the blue, the user began to experience issues waking from sleep, while using the laptop closed with external monitor, USB keyboard and mouse. Although a powercord was always connected, the machine seemed to be powering off.For a while, hitting the power button would boot things up again, properly, but not anymore. I have since disconnected all peripherials. Now, when pressing the power button, the machine will beep 3 times and then repeat itself every so often. The sleep led will blink three times, go solid, then repeat. Sometime the harddrive tries to spin, sometimetimes not

I know this is a fairly common subject matter but I have tried just about everything suggested but with no success. detailed below are my findings, I was wondering if anyone better qualified than me could suggest a diagnosis?
What does it do?
I hear the fans and hard drive and see the white/grey boot screen with the apple logo and spinning cog. The cog will spin for anything from 5 - 30 seconds before freezing. Some disk activity will continue for a short time afterwards before everything grinds to a halt?

I tried to install snow leopard on my 3 mos. old macbook pro and received a failure message with the invalid node structure, rebuilding catalog B-tree message.
Not sure what to do, I tried booting up from the leopard install disk and it took about 15 minutes to boot up and everything is wonky, doesn't work right.

when my PowerBook (15", bought new in Aug 2004) wakes from sleep, the harddrive makes a dreaded tapping/clicking sound. It's very prominent and is not your standard HDD "chatter."Often, Finder will hang and I'm forced to power-cycle the machine. Most of the time, it boots without incident.Lately, however, there have been incidents. Tonight, when I got home, it froze. I tried to power-cycle it, but got nothing. I plugged it in.

I have a 12" Powerbook G4 running 10.3.9 Panther. I am having problem booting my computer from a Firewire HD. I have done a search in the forum but cannot get a definite and/or successul solution. Forum moderators and my respected macrumor fellows, please feel free to direct me to a specific link if you find the questions redundant.Recently, I have had the HD making terrible noise and several days ago, the computer cannot boot at all. When I pushed the power button, the screen shows a folder in the middle with a Mac face and switches to a question mark back and forth. However, it just gets stuck at that stage. I suspected that I have a HD problem and wanted to boot from my clone Firewire HD. Unfortunately, the computer will not boot with Firewire HD either.

These problems still persist. even when i option to start up with my external drive, which i have mirrored my hard drive. it will boot up for the external then this clicking noise as noted above.

I have recently installed new RAM and an SSD in my late 2009 MacBook Pro, running OS X 10.6.8, and it now frequently hangs when I try to start it up. Here are details:Â
In recent weeks I noticed signs that seemed to point to a failing hard drive. I took the machine to a Genius Bar. The genius tried Disk Utility and a quick diagnostic and could not reproduce an error, but he noted many, many I/O errors recorded in a log file. Â
He said I probably had a failing disk, but it might be a cable issue. He gave me two options: leave the machine with Apple overnight to run diagnostics and perhaps repair if the problem was confirmed, or just take a chance and replace the drive myself, for less money and less downtime. Â
I went to a local computer store, and the salesman there noted that I was using relatively little disk space. He suggested that I swap my failing 160 G disk for a smaller, 120G solid-state drive, which happened to be on sale. I agreed and also bought some new RAM. Â
I installed the drive and RAM, partitioned the disk (with HFS journaling), and restored my files with Time Machine. For that day and the next, everything worked perfectly. Â
The second day after the installation, the system hung while starting up. The Apple logo appeared, the gray spinner appeared, and it just spun. I tried resetting PRAM. I tried safe restart. I started up from the install disk and ran Disk Utility: no problems found. I repaired permissions. I took out the new RAM and put back the old. In some cases after trying these steps, the system booted fine — once. In others, it would not boot the first time, but would boot on the second or third attempt. I reinstalled OS X and updated software. The problem persisted. I installed some freeware to enable trimming the new disk. No better. Â
I have booted many times in verbose mode. During the unsuccessful boots, there is usually a message "Bug: launchctl.c: 3557 (23930):6 ioctl(S6, SIO CAIFADOR_IN6, &ifra6) ! = -1". The next line is the command "fsck_hfs", and the machine hangs. Eventually it sometimes spits out "launchctl: please convert the following to launchd: /etc/mach_init.d/dashboardadvisory.plist". If I let it go for a long time, I sometimes come back to find a long string of I/O error messages, to the effect that media was expect to be there but wasn’t. I think every time I have gotten the launchctl message, it has booted successfully on the next try. Â
During the successful boots in verbose mode, everything happens so quickly that it is hard to say what is going on, but I don’t think it is running fsck_hfs. If it boots successfully and I give it a heavy I/O task, like doing a virus scan, everything works fine. If I run Disk Utility off the installation disk, it says the disk appears to be OK. Â
I started the machine in single user mode and ran fsck manually. It gave me reports similar to running Disk Utility, and told me the disk appeared to be OK. It then gave me the prompt for a new command. I typed "exit". It responded "logout". And hung.Â
One last thing: I just tried a couple of times to restart with the Apple Hardware test. Despite holding down the D key, the test failed to load, and after a long pause, the machine attempted a normal start-up. Â

I have a single boot disk with just the apps on, and 2 disks in a software mirrored RAID in which I keep all the important stuff.Its just occurred to me, if the boot drive fails won't the software RAID be destroyed as well?Or will it be easy to recover the data off one of the previously RAID1 disks, when the new boot drive is installed?

I've had my TIme Capsule for a few years now. Last year I decided to self upgrade the internal HDD to 3TB to actually fit back-ups from my two mac's at home. On my MBP the boot drive failed. It's unfixable unfortunately. how to restore full system on a new HDD on my MacBookPro from TimeCapsule, after boot drive failure?
how to connect the laptop with clean/ empty HDD to MBP and make it boot and install it all from Time Capsule. Moreover, I am not sure how to connect it to Time Capsule, so that it doesn't take 3 days to restore.There is both an ethernet port as well as USB 2.0 one too.Â
That 'old' boot driveis still barely running, I wanted to hand copy at least my iPhoto Library of 110GB in size, but it just keeps crashing, as the file is so big. I mean, I should have it all back-ed up on TimeCapsule,
