I can't boot into safe mode on my powerbook. I get to the gray screen it sits there for about 10 minutes and then reboots into regular boot mode. Any ideas what may be to blame and how to fix this?

PowerBook G4 17, 1.5GHz, Mac OS X (10.5.1), Mac Pro 2.66GHz

    I have the same problem on my G5 PowerMac. Can't get it to boot into safe mode

    Forgot to mention I use a software mirror RAID using Apple's Disk Utility. Perhaps that has something to do with it?

    For clarity, you're starting the safe boot by pressing the shift key immediately after you hear the startup chime, and not before?

    that's right. I've tried it many times (with 10.5 now and with Tiger before), always with the same result. I suspect a hardware problem of some sort but can't think what it could be.

    Have you looked at the Leopard discussions at http://discussions.apple.com/category.jspa?categoryID=235 ? I did a search on 'leopard safe boot' and a bunch of entries came up.

    I also can't imagine what hardware problem would prevent you from going into safe mode.
  • V.K. Level 9 Level 9 (56,130 points)
    the link you provided doesn't work for some reason. have you truncated it maybe?
    also, as I said, it hasn't worked in Tiger either. That's why I thought it must be hardware. I tested and changed my RAM but that had no effect.

    I clicked on the link and it went right to the Leopard discussion. If this doesn't work, at the top of the page you can click on discussions, then choose Mac OS X 10.5 Leopard.

    Same problem. Safe mode will not start with Leopard. Pressing Shift AFTER the start-sound, but after a few minutes my PowerBook reboots in normal mode, without any message.

    Maybe theres a hint in /var/log/system.log. I cant find any reason why safe mode doesn't came up...

    I've just looked at my system log and I can't find anything useful. how do you tell where the attempted safe boot ends and the normal one starts? I can't figure it out.
  • keelste Level 1 Level 1 (0 points)
    I hold down the Shift-Button after the start-sound. The white/gray start-screen with the little apple was shown about 5-10 minutes. Then the screen went blank and the start-sound played again and osx was normally booted.

    Also weird is the fact, that after I installed Leopard I am not anymore be able to boot on a Tiger-installation disc.

    Following steps are in normal startup:

    1. start-sound

    2. white/gray start-screen

    3. blue-background of OSX-GUI

    4. mouse-pointer appears

    5. ...



    Booting the Tiger-installation-disc will stuck in step 3. I waited about 45-60 minutes, but nothing changed. I'm not sure if this fact has any connection, but its possible that during the installation of Leopard something like a Firmware-Upgrade happened.

    My other suspicion is that I've a problem with my hardware... Memory or Mainboard... On the other hand, Leopard works very fine and I never had any crashes...
  • V.K. Level 9 Level 9 (56,130 points)
    sorry, I meant how do you tell in the log where the safe boot ends and the normal one starts.
  • keelste Level 1 Level 1 (0 points)
    Oh.

    The following line in the log directs on the safe-boot:

    ...
    Dec 31 00:19:24 localhost kextd[9]: safe boot detected
    -------------------------------------------------------------------------------- -

    If you boot in normal mode, theres no accordant line...
  • V.K. Level 9 Level 9 (56,130 points)
    yes,
    I've realized that of course. What I want to know is at what point it gives up on the safe boot and starts with the normal one. I can't figure it out from the log.
