I just updated to 10.6.3 using the System Update on my first-generation MacBook Pro. I'm now getting a kernel panic at startup, and cannot boot the system.

Specifically, I'm seeing:

panic(cpu 0 caller 0x2a96f6): "Version mis-match between Kernel and CPU PM"@/SourceCache/xnu/xnu-1504.3.12/osfmk/i386/pmCPU.c:720

I've tried cutting power, and attempting to start again, reset the PRAM/PMU, removed the battery and booted off AC power only, attempted boot into safe mode, and attempted boot into single-user mode. None of these operations have done anything. Additionally, I CAN boot into target disk mode, and have run Disk Utility on a second machine to repair volume and disk permissions.

Any thoughts on resolving this? Is it possible to downgrade, or am I stuck having to make a cloned disk, installing 10.6.2, and then transferring my files and settings back?

MacBook Pro, Mac OS X (10.6.2), MacBookPro1,1

    I would try the 10.6.3 combo. Seems to me your first setup was crippled and lacking somehow.

    If you use Time Machine, you could do a Restore from the Install disk. If not, then the last reply should do the job - -the Combo install.

    Good luck on that. Not good to hear about Panic issues after doing an Update. I will do mine later on tonight.

    Got a kernel panic on gen2 MacPro today using the software update to go from 10.6.2 to 10.6.3. Not a pleasant experience. Will need to carve out some time today to diagnose. This is a straight Apple machine, no external drivers.

    Do you by chance have a link to the Combo updater?

    Thanks.

    I too am having the kernel panic after install, I just yesterday bought a 640 WD drive as well as upgrading my RAM 2 to 4gb, i was having issues with all that and now the kernel panic on top of it, is killing me.

    I'm having kernel panics at startup too saying the same thing. I used the combo updater and all was well until I restored from a Time Machine backup.

    Most kernel panics are caused by hardware problems.
    UN- upgrade the memory and see what gives.

    What did you restore from the backup?
  • gpotts Level 3 Level 3 (585 points)
    I restored everything.

    The reason I did the restore in the first place was that boot camp didn't want to let me partition (probably from fragmented files). Anyway, I restored from my backup because it would fix that issue. After reinstalling the system using the DVD it started up normally, however all of my files were not the latest version. It looked as if it was all from a previous backup and not the current backup. I'm retrying the restore now. I'm guessing it probably isn't going to work but we'll see. Looking at the files on the backup HDD they are all the latest version but it didn't update on the computer's HDD after the restore.

    I'm asking as if you restored certain system components and left other pieces of 10.6.3 in place it could cause the panic.

    If you restored your entire system to a known good 10.6.2 backup, then there shouldn't be an issue.

    I dont know how to start a new post. I don't see it on the site so I am just going to tell you about my situation. I updated to 10.6.3 on a 2.66 MacPro from 10.6.2 and it rolled me back to 10.5.6 Now all of my users are gone and I dont know how to fix it. I took some screen caps. I can't believe this. How did I get rolled back?

    What you describe is impossible unless you have multiple hard drives installed, one had 10.5.6, and after the reboot you ended up booting from the drive with 10.5.6 installed.
