Kernal panic while re-installing OS

I recently bought a new MacPro and now I'm trying to get the old one ready for sale.
I removed the Boot Camp partition and then tried to erase everything on the hard drive using Disk Utility but it wouldn't let me do it.
I then tried to use the original Instal disk to do an erase and install but as soon as it started up I got the kernal panic screen.
Seeing as my old MacPro is a 2006 legacy MacPro but has been upgraded to Snow Leopard am I just creating problems by using my old install disk.

Thanks macbig, I read the article you linked to but couldn't find anything that lent it self to my problem.
I'm only getting the panic when I try to use my old original install disks to do a clean and install.
It could well be my updated video card but I was hoping I would not have to take it out and plug in the old one again.
I guess I will try the SL install disk and see if I can get something to work that way, at this point I have nothing to lose but time.
Like hatter recommended I did have a back up bootable disk for this computer but after I transferred every over to my new one I now use that as a backup to the new one.
I really wasn't worried about losing any data with the old one seeing as I would be fixing it up for sale and reinstalling the OS.

Kernal Panics when booting Install DVD on new MacBook Pro

First off, let me say that I know that Apple does not officially support OS X Server on their portable machines.
With that out of the way, I have been trying to install Server (the Universal Edition, of course) on the new Santa Rosa MBP that I got last weekend. The Installer DVD will kernal panic when trying to start up the machine. So I took it to my job, where we have a Mac Mini with a Core Solo processor. The Install DVD for 10.4 server boots the mini up just fine. So I put the MBP into target disk mode, and installed server on a partion I had made on the internet MBP disk when I first got it. So the installer has 10.4.7 on it, which I thought might be causing the problem. So with the Mini booted off the MBP partion, I updated the Server install to 10.4.10 and all the other updates. I then restarted the MBP, held down the option key, selected the server partion to boot up from, and the machine still kernal paniced while still booting up (It never gets past the gray Apple Screen with the spinning wheel.
Now I had hoped that the firmware update released today might help with the problem, but when I try to run that installer, it says that the firmware is not needed on my laptop. So I guess they had already installed it at the factory, even though it was not yet publicly availible.
I have looked at the kernal panic logs on the non server version of 10.4 that the machine boots after the kernal panic (when I boot back into server, using the Mini as the boot machine, there is no kernal panic logs), and I have always found the same thing, it looks like something to do with the video driver is causng the problem. The first item that is always in the backtrace is:
com.apple.NVDAResman(4.5.6)@0x500c4000
So I guess I am just wondering if anyone else out there, with a new SR MBP, has has similar problems trying to run server on their new machines?

The method you must use is outlined here:

Best of luck.

on the toolbar.
I had to restart with the power button because the mac froze, the mac started up,
but the screen remained black (with some sign of luminosity in an area not black as if off
I shut down again (w/ button) unplugged the mac waited 5 mins,
restarted and all proceeded as if normal.
I inserted Panthers Disc 1, did a restart holding the c key at chime using & did a repair disk in DU
I got a Disk was okay ..
I ran software updates via the Updater these are the ones I did.

Hi,
Yikes!
You said :::
After some time of having my mac off line and unplugged (about a year & 1/2)
I got it back on line and running.
There could be a problem with you logic board or the LCD, but hmm
I wonder if perhaps resetting the PMU may help, I think it maybe worth a try.
Have the person helping you do that.
http://support.apple.com/kb/HT1712
from the article above...
The PMU is a microcontroller chip that is present on the logic board in an iMac (Flat Panel). As the name implies, it's responsible for controlling all power functions for the computer such as power on/power off and some aspects of sleep/wake behaviors.
* In rare occasions the settings in the Power Manager may become unusable, which can result in operational anomalies with the computer. For example, your computer might not turn on, not wake from sleep, or do (or not do) other things.
Resetting the PMU is not intended to resolve issues in which your computer stops responding or applications unexpectedly quit. In general, you shouldn't have to reset the PMU except as a last resort in cases where a power management system hardware error is suspected. Performing a PMU reset returns the iMac hardware, including NVRAM, to default settings and forces the computer to shut down.
Before resetting, try this first...
If you're experiencing issues with your iMac, for most situations, a restart is sufficient. If your computer has stopped responding, try these steps—in order—until the computer responds:
Force Quit (Option-Command-Escape)
Restart (Control-Command-Power)
Force Shut Down (Press the power button for 10 seconds)
Reset PRAM
You should only reset your computer's PMU if none of the steps above resolved your issue. If this is the case, see the instructions below to reset the PMU in your iMac (Flat Panel).
Important: Resetting the Power Manager on any iMac (Flat Panel) will permanently remove a RAM disk (if you are using Mac OS 9), if present, and all of its contents.
Resetting an iMac (Flat Panel) PMU
To perform a reset you will need a Phillips "0" screwdriver. The instructions in this article cover these iMac models:
Best of luck & please keep us posted!

Kernal panic with software install and restore disc

I'm trying to access my software install and restore disc for my powerbook G4 running tiger. Everytime I restart the computer with the disc in, and hold down c, I get a kernal panic. There is nothing wrong with the software install and restore disc, as far as I can tell.
Thanks for any help!
Powerbook G4 Mac OS X (10.4.6)

is this a tiger disk or a previous operating system? if it is a previous os restore disk, then it is not surprising it would panic. the only software restore disks you would need would be ones to run the apple hardware test and to install or reinstall os 9. otherwise, you should not use a software restore disk for a previous operating system, unless you have erased and installed your drive.

Kernal panic while using iTunes.???? gulp....!

Ok aloha I was running along smoothly in iTunes after I moved all my music from my iTunes library from my powerbook and in the middle of a song about 5 to 10 mins after this the system crashed to a Kernal panic screen. I cannot start up when I restart or when I insert start up disk. Called Apple and they sent me to the nearest repair shop. Before I go is there any way this isnt hardware, and if not hardware then software problem is my expense!!! Yikes Thank myself I backed up prior. ANY guesses as what this must me?
ALoha Reid

Frequently, you can't boot off the installer disk because you tried the 'C' key for startup, when in fact the Option (also known as the Alt key) key works better. Also make sure no additional peripherals are connected when you try this. See if that works first. Here's an article on the Option key startup:
http://docs.info.apple.com/article.html?artnum=106178
Make sure only to use the disk that came with the computer that installs the operating system or a newer retail operating system disk as this article explains:
http://docs.info.apple.com/article.html?artnum=25517
If you can, repair the directory as my FAQ explains:
http://www.macmaps.com/directoryfaq.html
If you can't, well, you may have a hardware problem. If your machine is under a year old, you might want to purchase AppleCare so that this and future repairs to damage you couldn't have caused will all be covered under both hardware and software causes for another 2 years.

Kernal panics while using DVI output to watch DVDs

Hello all. I just got a new MacBook and LOVE it. The only problem is that when I use it to watch a DVD on my HDTV via DVI out and insert a dvd, I get the message that I need to manually restart my computer. This is the fresh factory installed copy of Leopard. When the computer restarts with the DVD in it, everything works perfectly. Has anyone else had this problem? Thanks guys!

I just plugged in the MiniDVI/HDMI adapter cable and I got a really flickery TV, does this suggest graphics card issues? If so how to I run a diagnostics test on Mavericks if I don't have the boot DVD? Thanks!

Kernal Panic after update to 10.4.6/Missing HD Space/Won't Startup from DVD

Sorry to lump three problems together, but they may all be related.
First - I was getting random Kernal Panics while at 10.4.5, so I attempted to update to 10.4.6. The computer wouldn't even come close to starting up. I got a screen full of Kernal Panic info. I reinstalled Tiger 10.4.3, and that's where the system stands now. It's running fine.
Second - My computer suddenly announced that the startup drive was out of disk space. I looked and the window said 30g. I closed the window and opened it again only to see it at zero k. I dumped some items to get some disk space, but now I can't get my 30g back.
Third - I want to startup from the Tiger disk like I did when I reinstalled, but it won't startup from the DVD. I'd like to run Disk Repair on the main hard drive. It showed some errors when I ran a Test using the Disk Utility.
I'm hoping this is all related. The computer seems to be running fine, but I can't update or find my missing space. Any advice I can get on these issues would be appreciated. Thanks.
Jon

Is your computer saving a panic.log after each of the kernel panics? You can see by opening Console (in /Applications/Utilities) and looking for it. I'm not at my Mac now, so I can't tell you under what section to look for that log.
When you try to boot from the CD, are you holding down the 'C' key as the computer reboots? You can also try rebooting with the Option key pressed, which will present you with a list of bootable volumes. It will also give you access to the Apple Hardware Test (if this is the DVD that came with the computer). If you can select the Apple Hardware Test, I'd recommend doing the Extended Test, which will test the hardware, including the RAM.
For the disappearing disk space, you could have some process that is going bezerk and filling up the log files. In any event, to see where you disk space is being used, download and run Omni DiskSweeper.

Freezing & Kernal Panics even after an erase/install!!!

I have a Macbook Book Pro 17 inch, 2.4ghz processor intel core 2 duo, 4gb ram bought in around June 2007.
Recently my computer started acting up randomly, it started to freeze up where everything didn't respond but I could still move my mouse around. But in the end i would have to do a force shut down.
Then after that, while it is in the gray loading screen, it starts to do a kernal panic message where the grey screen drops down, BUT the grey screen freezes up mid way while its dropping and i have to do a hard reset again! Sometimes the kernal panic will make it all the way down the page, but most of the time it won't.
So I decided to FSCK my harddrive and then that allowed me to log in and save off everything so I can just perform a whole new fresh erase and install.
After the fresh reinstall, I started loading all my applications today, but while I was in the middle of installing the final cut pro studio 2, it froze. Now it is starting to continue the pattern for freezing randomly when Im either surfing the web or using quicktime, etc.
I can't figure out what is going on.
The only thing I can think of is that it could be my external harddrive causing problems?
or
some crappy 3rd party software I installed?
or
faulty hardware - ie. ram issues? i dunno.
If anybody has a solution or something! that would be great.
The apps I loaded were basic apps like Final Cut studio 2, Adobe Creative Suite cs3, Microsoft Office 2008, logic pro 8, ilife 06, iwork 06.
Other non traditional ones (3rd party etc) would be
Adium, firefox, Cyberduck, Garmin webupdater, Tascam 144 Audio interface, auto tune 5, flip4mac, iAlertU, InsomniaX, itoner, SwapMyDock, Transmission, and You Control Tunes.
I hope this information helps. Thanks for hearing me out!

Please... take a look at this topic:
http://discussions.apple.com/thread.jspa?threadID=1769750&tstart=15
Until yesterday I was with the same problem.
In advance I'll tell you to run Apple Hardware test tool...
Put your Leopard DVD and boot with the "D" key pressed... and see what you get.
Good luck!

Mac Pro Kernel Panic while booted on install disk

I have a Mac Pro with 1 year and 2 weeks on the clock. No Apple Care.
Started getting intermittent Kernel Panics about 2 weeks ago, which are becoming a real problem now. Happening every time I use the machine.
I’m running 10.6.4 and just have the original ram etc.
Having searched here for related topics, I have been trying to troubleshoot the situation.
Was looking at recent software installs or likely culprits...
Ran the normal Apple Hardware Test and passed ok.
Ran an extended test and got this error: "4HDD/11/40000004:SATA(4,0)
Repaired all internal disks as far as possible, while started up on the installation disk, and when finished I got another Kernel Panic, while still running on the disk.
Can someone confirm if this means the issue if definitely hardware rather than software?
If so is it possible to tell which hard drive is at fault - ie. which Bay number corresponds to the SATA error above, if it is the hard drives at fault?
Need to get this fixed asap, so if anyone has any thoughts on how I should best proceed, that would be really appreciated. Thanks.

Hi experiencing simular issues
Initially I thought the error was related to too many different things on the machine, but have since done a clean install to 10.6 with FCP and CS4 only and the and the errors continue.
6 error-reporting banks referred to 6 of the ram chips, but i see that your report
states 9, ( you don't have 9 ram slots do you?)
Upgraded this of a volume disc so I don't have the hardware diagnostic for this machine on a disc, and would have to go back to the tiger hardware diagnostics which should not make a difference but I see on forums people claiming this is an error only with leopard and that their systems were fine under tiger. The ram has a life time warrantee (non apple) but I need to get it to fail a test other than this apple problem report.
The machine crashes are not software specific, I was hand writing with just a browser open and it requested that I would have to restart the machine. If would be easier to test any solution I I know that combo would crash the machine other than time.
I expect the next steps
are to reseat the ram
reset the p-ram
Regards

After install of Mavericks, it looks like my system kernal panics and just sits there. I tried waiting over two nights. Tried reinstalling twice, booting r/s. Recovery partition now has Mavericks as OS. Im running a iMac i3 27 inch circa 2011. Any ideas?

After install of Mavericks, it looks like my system kernal panics and just sits there. I tried waiting over two nights. Tried reinstalling twice, booting ro the repair partition and repairs permissions/drive/verify , with no problems. Tried reseting PVRAM(or whateverit called). Recovery partition now has Mavericks as OS. Im running a iMac i3 27 inch circa 2011. Any ideas? Can still bootcamp into windows.
Thank you

The file seems to create the CD/DVD/Image and USB just fine. So I used this only to create a CD image which I then wrote on a blank CD which seems to work fine. Also, I played around a bit and had some partial success in booting the partition. I've updated my original opening post with the new findings.
Whew!! what a waste of time! Never want to do all of this again .

Kernal Panic with OS 10.4.6 install

Repeated attempts to install OS 10.4.6 over 10.2.8 each time resulted in kernal panic. Despite restarting from outboard Firewire HD and using Disk Repair to correct permissions and repair the Macintosh HD, no joy followed. TechTool Deluxe 3.0.3 reported no HD problems. Taking the CPU to the MAC Store resulted in a successful install by the technician who repaired permissions and severe directory damage. Happily, I reconnected all previous cables at home, started up the MAC, and immediately noted the return of kernal panic or, finally, the MAC Blue Screen of Death. Disconnecting the SCSI cable (connected to Adaptec SCSI Card 2906) from an Iomega Zip Drive resolved the problem. I should have known that the SCSI device could be the cause of this problem, but I missed seeing the other reports in the Installation & Setup section when searching the terms “kernal panic.”
Entering “SCSI” as a search term does produce numerous messages regarding incompatibility problems, such as this long chain, “No luck getting Adaptec 2906 SCSI card to work.”
PowerMac 867 MHz Mac OS X (10.4.6) RAM: 256MH then >> 768 MH now

J.Michael:
Kernel panics are usually hardware based. If you have recently installed RAM or a peripheral your problem may be related to that piece of hardware.
Check out Dr. Smoke's Resolving Kernel Panics and see if there are any clues for you in it.
Good luck.

Kernal panic after failed Leopard install

Was upgrading a MacMini from the installed 10.4 system to 10.5. The install reported a problem reading the DVD during the first phase of the install (when the DVD and platform was being analyzed) and before any install started.
Rather than removing the DVD, I went ahead and ran the install a second time, this time hitting SKIP during the first phase. This move the install to the actual install which tried to start but stopped after less than a minute again reporting a problem reading the DVD.
Since I wasn't sure how to eject the DVD from within the installer, I decided to boot using the 10.4 installed system. Within seconds (just after the apple logo was displayed) there was a kernal panic. A complete shutdown and reboot of the Mini failed to solve the problem and the panic occurred again at the same location in startup.
I got help on how to remove the DVD and, sure enough, it did have a water spot which I cleaned and re-ran the 10.5 install which was successful. I'm able to boot the new system with any panic.
I ran a repair disk just to make sure there wasn't some other problem that might have been unrelated to the failed install but no errors (other than a couple APL not found messages) were found.
My intent is to migrate from a G4, now also running 10.5 but this experience has left me a little concerned that there may be a problem on the Mini that may not have been resolved through the successful Leopard install.
Are there other tests or utilities I can run to get more comfortable that the panic is gone before I do the migrate?
Thanks
Tom

Use the Apple Hardware Test program that shipped with the machine and then follow up with running Rember. Once that's done, install Leopard and migrate from the G4, make a bootable backup/clone of the new installation, and then apply any subsequent updates.

Re-Install result in Kernal Panic

I was running 10.6.6 and had a time machine back up. I had to re-install so after following Apple instructions, I installed my 10.5 disc and then installed 10.6. I then inserted my 10.5 disc and from utilities chise 'recover' to recover from my TM backup. After the recovery process finished, about 6 hours, it asksed me to restart the machine. I did so and got the 'You need to restart your computer.." kernal panic message.
Everytime I now try to restart the message keeps coming back no matter which keys i press. Nothing I do will stop the message. I'm very frustrated that something like this has happened after following Apples instructions. Its a simple re-install and didn't expect all this to happen.
Anyone recommend a solution?
Many Thanks
Mike

Did a re-install as my mac was really slow after several tools to improve performance. It needed a fresh beginning
Unlike some other operating systems, that's rarely required on OSX, and usually doesn't accomplish anything (well, not anything good).
I tried to restore TM backup from Snow Leopard but when it returned a message saying it could delete the HD in preparation for the backup.
Yes, to do a full restore, the destination must be erased first.
In the process of trying again so will post an outcome.
As mentioned in #E8, either do a full restore, or reinstall OSX (and the "combo" update).

Kernal panic with install disk

Hello.
I've successfully used my SL install disk to launch Utilities on my G5 and switch Firmware Password on, so I know that the DVD is OK - it's the Apple original. When I try on my MBP, the boot repeatedly stalls on the gray Apple screen then gives me a kernal panic message to switch off. The install disk mounts OK when I've booted from the HD but won't restart from the disk. They are both running SL 10.6.7 with everything up to date. The MBP works fine in every other respect but I can't set a firmware password on it.
Thanks.

Sorry, did I get the name of my Mac wrong?

Processor Name: Intel Core 2 Duo
Processor Speed: 3.06 GHz
Number Of Processors: 1

The disk is Apple retail.

Kernal panic after installing LR3- now after re-install,no privileges

I installed Lightroom 3 and in 64 bit mode it crashed the system with 'kernal panic'.
Managed to get it working in 32 bit (slowly) but was advised to re-install 10.5.8 as I was getting ACL found but not expected errors when I tried to repair permissions.
I re-installed but now find I have no administrator privileges - so can't do any updates etc;
managed to do: Installer>Utilities>reset password - but it still says password is wrong.
I also had used Time Machine to back up my system : when I tried to restore, the restore button is greyed out - I can select on various items, but that is as far as I can get.
Am at my wits end - don't see why the re-install has caused this problem

If all else fails, you can reinstall Snow Leopard using the same installer disc you used to install it originally (or your grey system discs if your Mac came with Snow Leopard installed). This will not erase your user files but you will have to update the OS & Apple-supplied apps after the installation. This isn't as painful as it sounds if you use the Software Update app immediately following the first normal restart after the installation completes. Software Update is smart enough to pick the most appropriate update(s) to get your Mac back to the latest software, including automatically picking the Combo version of the OS updater if the installed version is more than one minor version behind the latest one.
In fact, given how slow a Time Machine restore can be, if you have a fast high speed Internet connection this could take less time & effort on your part than doing the TM restore. Plus, it guarantees that you get the latest versions of everything & that they are all properly linked.
