Kernel panic after 10.5.6 download

Welcome to Apple Discussions:
Are you sure it's a kernel panic? Does the screen get dark with words in many languages saying you have to restart?
If so check out these links- it's probably RAM, although since you are running limewire, anything is possible since you have given access to anyone to use it. IMO, limewire is malware, along with all other bit-torrent stuff.

I would also download the 10.5.6 update manually from here:
http://www.apple.com/downloads/macosx/apple/macosx_updates/
and reapply it.

You will need the startup DVD no matter what, so if you lost it, call Apple and get a replacement. Their contact info is at the bottom right of these screens. Without the Leopard DVD there is little you can do.

BTY, your memory (RAM) is "wiped" each time you restart. I think you meant to say harddisk.
However, an Archive & Install does not remove any existing apps you your HD. It only restores the system files to those on the DVD.

I have exactly the same problem. Tried to install Mac OS X 10.5.6 update... getting kernel panic now and cannot start the computer 😟

I have the same problem, since updating to 10.5.6 i get a kernel panic when booting, i can boot into safe mode and then restart into normal mode, at the same time my macbook won't shut down properly, if i click shut down from the apple menu then it will shut down and the screen goes black but it won't properly turn off, if i shut the lid the light on the front turns on. My computer also won't sleep and doesn't have any sound. I downloaded the 10.5.6 combo update but when i try to mount the disk image i get a kernel panic.
Any help please.

I have the exact same problem!

I had the same problem today and promptly took my macbook pro to nearest apple dealer to have them have a look at it. Was anyone able to fix this themselves? I'll let you know what I find out they tell me at the store.

I thought I had downloaded the 10.5.6 update successfully, BUT I'm having a kernel panic every 20 minutes since then. Each time it happens, I've been watching .avi files in QuickTime Pro. My kernel panic looks a little different, perhaps because I'm on a PPC G4? It's looks like white text across the screen with black behind the text.

Before today, I had kernel panics every few days or so, I suspected it was caused by the installation of several Adobe Air apps (Twhirl & TweetDeck) as I hadn't had a kernel panic since a clean install of Leopard, UNTIL after the Adobe Air apps were installed. I can live with a kernel panic every few days, but now after the 10.5.6 update a kernel panic every 20 minutes is beyond ridiculous.

Disk Utility's Disk Verify says everything is fine, but permission repair gives me several warnings that I have no clue what to do about:

Warning: SUID file "System/Library/Filesystems/AppleShare/afpLoad" has been modified and will not be repaired.

What's the best course of action?

Don't feel bad people, I think Apple is caring allot less about the Mac and worrying more about the Iphone and Ipods these days. I upgraded to 10.5.6 and my first generation MacBook that hardly ever gives me problems is kernel panicking itself to death. My 1st generation quad 3Ghz Pro is now kernel panicking itself to death (both computers giving same kernel panic code). I have about had it with Apple and I am considering heading back towards Microsoft. Apple has proven they can not do any better than Microsoft. It just works, whatever. I wish you all the best of luck.

installed 10.5.6 combo update as the kernel panics started again. now computer kernel panics right after i boot up & it won't boot from leopard disc at all. Am using my phone to post this. can anyone post some links to any other threads that might have answers and any links to key combinations to boot with? holding the C key doesnt work. help!

my computer just keeps spitting out the leopard dvd. I am trying to boot from my dead PowerBook's hard drive using a firewire enclosure which is running 10.4.11 & it still spits out the dvd. any links would be appreciated as my phone's browser, operamini, is so small it's difficult to search and manuever through apple's support site.

hey - I had updated my 17" MBP to 10.5.6 via the software update recently, and had similar problems to what everyone is saying. I found an interesting issue - in the process of archiving and installing from the Leopard retail DVD, my machine would have a (kernel) panic attack only when the disc was in the drive - even booting up wouldn't get past the grey logo screen until I forced the DVD out at boot.
Clearing PRAM and NVRAM were only temporary fixes, and regular CDs and DVDs seem ok - it is the Leopard disc only that takes down the system.

hopefully this gets addressed. I will try to somehow reinstall and apply the 10.5.5 update and see if the DVD continues to crash the system.

good luck to all

I've had this problem on my mac book after every reboot. But not any of my other macs. The only way I have found to fix this is to re-boot in safe mode. Then re-boot normally and everything is OK, until I re-boot again. If you look at the mac help page on safe boot there is a bit of a give away

"Mac OS X 10.5.6 or later: A Safe Boot deletes the dynamic loader shared cache at (/var/db/dyld/). Restarting recreates this cache. A cache with issues may cause a blue screen on startup, particularly after a Software Update."

I hope Apple will fix this in there next update.

I hope it's fixed in the next update too! I think i can deal with the kernel panics by starting up in safe mode and restarting but i have the problem of having no sound, my macbook will make a start up sound but then once started up there is no sound icon in the bar at the top of the screen and whenever i try to adjust the volume i get the normal volume box but with the circle with a line through it. In system preferences it claims that there are no inbuilt speakers, which i know are working because my computer will make the start up sound. Does anybody else have this problem? (i know it's a different problem from the rest of the discussion).
