Software :: Macbook Pro Will Not Boot Safe Mode Kernel Panic?

Nov 10, 2010

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?

Intel Mac :: Keeps Booting In Safe Mode Plus Kernel Panic?

Apr 17, 2012

a bit complicated.   I have a 3 year old iMac, Snow Leopard 10.5.2 on the dics, but I updated it so..a pretty receent version of Snow Leopard. I had had kernel panics before- it turned out to be a bad RAM chip, replaced it and it fixed the problem. 

This time, I was hoping it was the same. I got a new RAM chip, swapped them out and ID'ed the bad one.  Reseated the RAM. Probelm is, when I was trying to fix the problem, I had booted in Safe Mode.  Now the iMac starts up normally- the chime, the Apple- AND the Safe Mode bar.

Which progresses for about 5 seconds before another Kernel panic descends.  This happens whether the keyboard is connected or not.  At this point the Safe Mode at startup bugs me more than the kernel panics! Sigh. 

I wonder if there's any key combo on startup I could try to at least get out of Safe Mode before Kernel panic sets in.  When my laptop has a kernel panic i can usually repair with Disk repair on CD.   I realize this sounds hopeless!  And i need it repaired, but money is an issue.

OS X :: Won't Work With Kernal Panic / No Safe Mode And Target Disk Mode

Jul 6, 2010

I have a 15" mbp with 10.6 Intel core duo, 4gb ram with a boot camp and ubuntu partition through parallels. The other day I was installing xcode from apple's website, which failed 3 times after downloading saying the package couldn't be expanded. I left my computer for a while and came back where i then had to log in again. it rejected my password numerous time (i'm positive it was correct). when i restarted my computer i got a kernal panic screen when the apple logo came up. it told me to restart the computer which i did. didn't work. i restarted with the osx cd to use the disk utility. when it checked the drive it found a bunch of errors, which i then tried to correct. it went for a couple minutes then told me they couldn't be fixed and i should try to back up my data and reinstall osx. i don't know how to back up my hard drive when i can't log into my account. i've tried to boot in target disk mode and copy some files that way, but the only disk the other computer sees is my windows partition- no mac partition.

i've also tried these, none of these have worked: restarting in safe mode resetting the ram and pram booting with different sticks of ram all result in a kernal panic.

my windows partition still works fine though (as much as i hate to say it) the only things I really care about on my computer are my files from school and my itunes library. is there any way i can get these files off my computer?

OS X :: Fixing DFU Mode And Kernel Panic On Start Up

Feb 7, 2009

I was following the directions from the iphone dev team's blog on how to fix the DFU mode in 10.5.6 by dl'ing from Apple and installing the "IOUSBFamily-315.4-log.dmg" for Mac OS X 10.5.5 Build 9F33. After I installed it and restarted as the directions stated, the machine started to reboot and then had kernel panic on start up. Now I can't get back the start up screen. I've tried disk utility and repairing permissions but it hasn't helped. What I can do other than archiving and installing?

MacBook :: It Won't Boot After Trying To Repair With Disk Utility, Cannot Boot In Safe Mode

Jun 11, 2012

I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD.  

I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc". 

I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.

Mac Pro :: Unable To Boot / Kernel Panic At Boot And Graphics Card Failure

Mar 9, 2008

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. 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.

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.

MacBook Pro :: Will Not Boot Up - Not Even In Safe Mode

As of yesterday my Mac book pro will not start up. It will not go past the gray screen with the apple and spinning timer indicator. When I try and start up holding shift to enter safe mode it will not start up either. I have tried turning It on and off many times. I am not sure what to do or what the problem might be.

MacBook Pro :: What Can I Do In Safe Mode To Fix Boot

Jul 5, 2012

MY MBP is giving me the "NOT" sign on start-up. This comes after initially displaying the Apple logo. This MBP had a new logic board installed by Apple just two weeks ago -- and I know I can take it back but I'd like to fix this myself. I put in a different hard drive after getting the MBP back. It has worked fine for several days. Don't know if these points are relevant, but:

1. First thing I noticed today is that neither of the USB ports would read a flash drive. The port would, however, work mouse and keyboard.

2. The initial non-boot episode took place when I had external hard drives daisy-chained in via Firewire. But, again, this had worked previously, as recent as this morning.This may be significant:

3. The last tasks performed on the MBP were -- for the first time -- to edit video in FCE, make DVD in iDVD, burn IMG file. 

4.I have connect this MBP as a target FW drive to another MBP and run "disk verify" and "disk repair" in Disk Utility. It says the drive and permissions are okay.

5. I have booted to a copy of Disk Warrior (latest version, version 4, I believe) and rebuilt directories and files along with verify/repair permissions (everything DW will do). And when re-starting, it still won't boot.

6. When I boot off Snow Leopard DVD and run Disk Utility¦"verify disk" says "the volume appears to be ok¦.when I "repair disk" it reports "Volume repair complete." and "Updating boot partitions for the volume as required."

7. I'm able to boot in SAFE MODE, but when I try to restart in normal mode, it won't boot (so nothing was automatically fixed)What can I do in safe mode to address my problem?

Software :: Macbook Won't Boot Up Even In Safe Mode?

Nov 27, 2008

I have a Macbook which just reboots constantly, you see the apple, the little whirly graphic that tells you it's starting up, then off it goes, chimes again and the same thing over and over again. I can't start up from the Install disc, it just keeps rebooting, I've zapped the PRAM not made any difference, won't start up in safe mode either. I've run disk uitility on it from another mac (Target Mode) but it said the disc didn't need repairing, and still it keeps on re-booting, over & over & over....

OS X V10.7 Lion :: MacBook Pro Won't Boot Into Safe Mode

Apr 29, 2012

I am running OSX Lion latest version on my Macbook Pro 4,1 and can't get the thing to boot from any source. Always get's stuck at the grey screen with apple logo. Have tried all the following...

- Straight Boot (power on)
- Boot via Recovery HD (hold option on bootup then select)
- Boot via Safe Mode (Holding Shift on bootup)
- Boot via Safe Mode Verbose (Shift, Command, V)
- Boot via bootable Lion USB Key (Hold option, and choose the USB drive - not the same USB key works on my other macbook pro)

On every one (except verbose) it just get's stuck on the grey screen with spinning timer thingy. I have done PVRAM reset, SMC reset and have reseated the RAM and all to no avail. I'm pretty sure the problem was caused by removing battery at wrong time (device not responding after sleep mode started and I plugged in power - should have been more patient!)

I have a Time Machine backup but it's a bit older than I thought and very much want to get my newer photos off it before rebuilding - not that Time Machine would work in current state anyway. So what are my remaining options? Will I have to open it up and remove the HD as next step or is there anything else left to try? Can I remove the HD and connect it via a USB caddy to my existing Mac to recover info (hard drive spins and sounds ok to me)?

OS X :: Cannot Boot From Any Media - Kernel Panic On Startup

Nov 16, 2009

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.

OS X :: IMac Crashing - Kernel Panic On Boot Up

Dec 10, 2009

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.

OS X :: Kernel Panic At Startup - Unable To Boot

Apr 21, 2010

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?

Intel Mac :: Kernel Panic At Boot And Sometimes During Runtime?

Apr 23, 2012

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?  

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:

MacBook Pro :: Running OS X Mavericks 10.9.4 Will Only Boot In Safe Mode

Aug 25, 2014

I have a macbook pro 15-inch, Early 2011 running osx 10.9.4. I have a SSD hard drive that i installed myself a year ago and hasn't shown any defects. Its a 120 gb OCZ-AGILITY3. 

My macbook will only boot in safe mode nowadays. I have done a complete erasion of my hard drive and installed osx mavericks twice already. After the installation the computer will safely go to the desktop. But if i then do a reboot it won't get further than after the first apple logo, sometime the turning wheel will pop up, before turning off and trying again. i have tried resetting PRAM, I have tried resetting SMC, i have tried avoiding SMC (with big fan rate), but all with no success. 

I have done a complete hardware test (the longer one) and it showed "no troubles found". 

My guess is that the problem is with the battery. My computer won't run anymore without the adapter, when i pull the adapter out it either stays on for a while before just turning off. Without having it plugged in it won't start. Is it possible that during normal start up there is some kind of communication with the battery that can cause this? 

I ran a diagnostic shown in this thread (Will only boot in safe mode) and included it in this post.

Start time: 17:07:42 08/25/14  
Model Identifier: MacBookPro8,2
System Version: OS X 10.9.4 (13E28)
Kernel Version: Darwin 13.3.0

MacBook :: Circle With Slash At Startup - Cannot Boot In Safe Mode

Feb 25, 2010

I was troubleshooting an issue my brother was having with his Macbook over downloading files, installed Firefox for him, ran Apple updates and while the updates were installing the computer froze. He restarted it, and on startup he got a circle with a slash through it. I've been googling and checking forums and I tried booting into safe mode (Shift at startup, I believe?), and putting in the OS X disc that came with it and booting from that (C at startup?) but I get nothing. It just goes from the Apple with the loading circle, to the picture of the slash circle. I'm not really sure on the specs of the computer or the OS version, as I'm rarely on it.

MacBook Pro :: Starts With Black Screen Only - Same When Boot In Safe Mode

Dec 6, 2014

My MacBook is making the startup sound but goes straight to a black/dark grey screen. In other words you can see the screen switching on but it's blank. It's in charge mode, has no other external peripherals attached and it's updated to most recent OSX Yosemite.

I only purchased it in May of this year (refurbished). I have tried booting in to safe mode but again the screen remains the same.
