Today I insalled via software update Mac OS X on 2 intel machines: 1) a 2 x3 GHz Dual-Core Intel Xeon tower and 2 ) a 2.33 GHz Intel Core 2 Duo MacBook Pro.

On both machines after pressing the button to restart at the end of the installation process I held down Apple S to boot into single user mode and typed Applejack Auto Restart.

In both cases shortly after beginning the machines locked up with the message kernal panic, debugger called and some numbers.

I am using Applejack 1.4.3 which seems to be version that is currently dowloading from your web site.

    Issue on G5 is not that bad, quad G5 here and when I had to move to single user mode I noticed there are no traces of applejack, the startup banner is gone and when you type "applejack" it says "command not found". I reinstalled as result.

    I have just booted in single user mode after reinstalling applejack. I have run Auto (selecting a in menu) and cleared specific users cache (mine), all works fine on PPC.

    So, let me get this straight. Fresh installs. Installation of AppleJack (with no reboot between the fresh install and the installation of AppleJack. Restart with Cmd+S. Invocation of AppleJack. Bang! Is that right? I assume that by "soon after" you mean when the permissions repair process initiated its own little system bootstrap. IMPORTANT: If it happened during disk repair or at some point other than the startup of the permissions repair process, let me know.

    I have had one similar experience. It happened upon the first invocation of AppleJack aftere install. Subsequent runs were fine. And that was on a G4 iBook.

    This will be very hard to pinpoint, so hopefully other users will post their experiences here as well so I can start discerning some pattern maybe.

    The sad fact, of course, is that since there is precious little documentation from Apple on single user mode, and none at all on what diskutil needs in order to launch and function in single user mode (diskutil runs the permissions repair), all the development I do has to happen in a black box where I can only experiment my way towards something that works. I wish Apple would document diskutil, but they have refused my requests with "that is not a supported user scenario."

    Anyway, sorry you had trouble and thanks for the report. We'll see what can be figured out.

    Can a shell script cause kernel crash? Or there is a problem on client machine which gets triggered when shell script runs?

    It is simply like Apple script causing kernel crashes. Impossible IMHO.

    Even if Applejack was an administrator running actual C program, it shouldn't be "able to" crash the entire OS kernel.

    I know developers aren't so fond of it but I suggest enabling "versiontracker alerts" for all entries (comment/bug report etc) and wait for other Intel based Mac users feedback until you accept this as a valid report.

    I was just able to reproduce this.

    And in the process I realized what is happening. After a major upgrade/install, there are several processes that the installer runs upon the next reboot that have to run. If you try to boot up in single user mode and then run either AppleJack or sh /etc/rc, these things will not have had a chance to run and your system will be configured in an inconsistent state.

    ALWAYS let your OS restart in the normal way at least once after an upgrade/update before running AppleJack.

    Thanks.

    I'm experiencing the exact same problem. Cleaned out my caches in 10.4.10 to help with a USB problem, and I'm getting the panic message. Can't even restart from a CD. HELP!

    nobody (2007-07-24): You are not experiencing the same problem. You do not mention this happening right after installing 10.4.9. If you are experiencing an unrelated kernel panic while using AppleJack, please open another support request instead of hijacking this thread.

    However, the fact that you can't startup from CD means that the problem has nothing to do with AppleJack, or your OS install--since nothing on your hard drive should be required to start up from CD. In fact, you should be able to start up from Cd even if your harddrive is totally dead. If you can't startup from CD, you need to take the computer in for repair.

    (Please don't respond to this thread. It is for another issue.)
