I cant get it to work, I still have to hold down "6" and "4" to boot into 64 bit mode. I edited and verified the changes in my com.apple.boot as described here but it still boots into 32 bit mode.
View 4 Repliesa 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.Â
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.Â
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.

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.
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.

I'm having a weird problem with a 15" I bought in February (2009). I can boot up fine into the OS without any problems. But when I try to boot from the reinstallation CD to do a clean install, I keep getting a kernel panic. (And yes, I do need to do a clean install.)

When I start up holding "option" and select to boot up from the DVD it goes to the apple logo and on to the kernel panic. When I start up windows via bootcamp everything works fine.

View 1 Replies View RelatedYesterday I purchased a INtel X25-V SATA SSD and installed it in my 13 inch MacBook Pro. Upon booting to a CD so I could install OS X 10.6 on the new drive, I received a kernel panic. After numerous tries I then put the old hard drive in (now clear of any data) and tried to boot to a CD again. Same problem. Now I seem to be stuck with a computer that will not boot to the CD no matter which hard drive is installed. I am able to use the SSD/HD in target disk mode. I can even install OS X to it from a different computer, but then when I try to boot on the MacBook Pro itself, I receive the kernel panic. The kernel panic seems to occur regularly after the Mac tries to load the CD for a minute or two.
Today I was preparing to get rid of my bootcamp'd windows7, change the partition size, and install XP. Well, I decided instead that I would just get a fresh OS X install, and install XP through the new bootcamp. So, I popped in my XP disc and went through the partition manager that comes with it (I don't know how to do it through mac) deleted all my partitions and installed windows so I could operate the cd-drive, and put in my OSX install disc.
(Perhaps I should mention I formatted it all to NTFS, thinking I could just reformat the whole thing with the OS X install like you can with windows). So, now I have a full NTFS partition, XP works fine. I can put in my OS X cd, restart and attempt to boot from a cd either from holding down option, or c at boot. When I try to do this, it pops up the kernel panic power icon, and gives me the "restart your computer" message. In recap my computer kernel panics on boot from cd.
Here's the question: Is this a true kernel panic, or is it due to the fact I don't have a partition available for mac to boot from? I didn't change any hardware, it was working perfectly fine prior to the -attempted- reinstall, and my XP install is working fine (minus the drivers), and after some research kernel panics tend to happen after hardware failures, in fact I had one happen a few months ago when my video card bit the dust.
my used eMac 1.42 ghz with 2gb ram, tiger 10.4.11 began to freeze a few months ago so I cleared the hard drive and reinstalled = worked ok for a while. Now, it is regularly freezing and even locking up when it has been running for a while - when it heats up. Until it cools off a while, on restart or after shutdown, it will hang at the grey screen or display a flashing folder with an alternating finder icon and a question mark - I assume it can't find the OS. After rebooting, I got the report function with this info
View 1 Replies View RelatedI'm relatively new to Macs and I wanted to try a clean install (or erase and install) on my ibook. I recently purchased a MBP and since Leopard is on the horizon, I wanted to do a "trial run" of installing an updated operating system. I know that you can just hit update instead of doing a clean install, but I've been reading that things run better when you do a fresh install. My old ibook still has Panther on it and I figured I could try to install Tiger on it from my MBP disks.
I know that this represents a violation of the license, but I thought it would be worth it to ensure that I don't make any major mistakes when I'm doing the same procedure with my brand new MBP when Leopard gets released. When I tried booting from the disk from my ibook I got a kernel panic which I interpreted as a sign that it was not a good idea so I abandoned the project. Now every time I try to start my ibook I get another kernel panic and I'm afraid I just broke my old computer.
I have a Macbook Pro 17" (Model A1229). Since some days I am unable to boot into OS X. Regardless if I boot from internal hard drive, external USB drive, Mac OSX Install DVD or an Install Image of OS X on a USB Stick. Every time I boot OS X I get a kernel panic after some seconds. Sometimes the grey spinner (below the apple during boot) just stops spinning (no kernel panic then).
In the beginning I was sometimes able to boot into OS X but it only lasts a few minutes or seconds and then freezes or I was getting a kernel panic. Now I always get the freeze or kernel panic during boot up. As it also happens when booting from external sources it can not be the internal hard drive (also already changed that drive). So I thought it must be the logic board or something but I can run windows 7 on the machine without any problem! I already tried SMC and PRAM reset...

I am on 10.6.4. I have learned that I can boot up in 32-bit mode by holding down the 3 and 2 keys while starting up. Is reverting back to 64-bit mode as easy as holding down the 6 and 4 key? If not, then what?

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?

View 2 Replies View RelatedMy MBP (about 2 years old, Santa Rosa) is having some major issues both starting up and going into sleep. First off, I'm using 10.5.8, everything's updated, I don't have a bunch of stuff on the startup processes (quicksilver and iTunes helper) and I'm plugged into a power source. When I start my computer (since yesterday) it has been taking an abnormally long time at the grey screen before the Apple, the grey screen with the apple and the rotating wheel, and then it goes to a light blue screen for 5 or so minutes (repeat: minutes) until flashing light and dark blue and finally taking me to the login. Not only that, but my computer will not go to sleep when I close the lid. Instead, the screen turns off and the hard drive and fans keep chugging. What's more annoying is when I then try to open the lid to manually turn it to sleep, the screen won't turn on. This usually requires a hard reset, which then takes 10 minutes to start up.

View 1 Replies View RelatedAt one point I had my external monitor set up to work with windows, so I know how, but since then I have reinstalled windows. I haven't used windows in a long time, so didn't bother setting it back up. Recently, my macbook's screen broke, I can boot into OS X fine by plugging in an external keyboard or mouse, or simply by closing the lid quickly before the primary display loads, thus booting it into clamshell mode using only an external display. I cannot however do this with windows, and since my screen is broken I cannot set the display properties as I cannot see them. Is there any way to either boot windows into clamshell mode or set the display properties using keyboard shortcuts?

Running OS X 10.9.3Â
When booting from an external firewire drive, on which I have OS X 10.9.3 installed, my Mac completes the boot sequence without going to sleep. I have run the OS X installer over my current installation, (without wiping), and the computer still goes to sleep once the boot sequence has completed.
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.

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?
