When I startup my Macbook, i get the apple picture for a minute or so, then the drives slow down, and I get a cirlce with a line through it, as in "no." I was using it, earlier in the day, and it locked up, when I was trying to eject a memory stick. I then turned it off by holding the power button. A similar thing happened later, and I again, restarted via power button, and then it would not start up again.

I am in a particularly interesting situation, because I am currently in Germany, and my backup disks are in the US. I would prefer to not wait until they can be shipped here, and I was wondering if there is anything I could do now to troubleshoot the problem. Also, I was wondering if just buying Leopard, would have the possibility of helping the situation.

Also, I am not one hundred percent certain exactly which 10.4.x I have, but I think that x should be 4.

Any help would be greatly appreciated.

Thanks

Macbook, Mac OS X (10.4.4)

    Welcome to the Forums!

    Really, the best bet is to use the original install DVD to run Disk Utility. You should start with a healthy disk before installing Leopard, so I wouldn't recommend that as a solution.

    However, there are a couple of things you can try first. You can try booting with the option key pressed, which runs a few basic disk checks. If that fails, you can boot with command and s keys pressed to start in single-user mode, then at the command prompt, type /sbin/fsck -fy to run a more involved series of disk checks/repairs. You may need to repeat this step a couple of times. These steps are described in this kbase article.

    FYI, the earliest MacBooks shipped with 10.4.6, so you should have at least that version, even if you never ran Software Update. Current version of Tiger is 10.4.11, so once you get back up and running, I'd recommend running Software Update to get current.

    Hope this helps...

    It helped in one sense of the word. I now know more about the problem, however it seems to me that the cause it definitely a corrupted OS. I get what other threads in forums have called a 'Kernel Panic.' With that being noted, and in the event that I don't have enough HD space for an Archive and Install, is there a way to take the hard drive out of my MacBook, put it into another and remove some items, that would not completely void my warranty?

    Actual error:

    .Looking for kernel cache file 'System\Library\Caches\com.apple.kernelcaches\kernelcache.C41226E9'
    Couldnät get file info.
    Loading 'mach_kernel'...
    .Error loading kernel 'mach_kernel'

    Also, at the risk of exposing my ignorance, is there a definite uniqueness to the backup disks that came with my computer, as opposed to those that came with a different but similar Mac? More exactly, if I found someone with similar backup disks, would that buy me anything?

    Thanks again.

    Removing the HDD from a MacBook (non-Pro) is ok, as it's considered a user-replaceable part. Not sure how that would benefit, since if it won't boot your MB properly, it won't boot theirs, either. Instead, consider connecting via FireWire and booting your MB in FireWire Target Disk Mode, so your HDD mounts as an external drive on the other Mac's desktop.

    There is some degree of uniqueness to the install DVDs, in that they are machine- and build-specific. So, you'd need to find someone with the the same model (i.e. MacBook) from the +same release date+ as yours (i.e. if you have a revA Core Duo MB, the install DVDs from someone with a Core 2 Duo MB will not work for you).

    I realize it has been a while, but again at the risk of exposing ignorances, if i am able to get into the installer, and it seems to be working, is there a risk of it not actually being the correct disks? And should I use the wrong disks, what exactly would the problem be?

    That you can boot into the installer is no guarantee that the disks are correct. If you try to install and they are incorrect, you will make any existing problems worse. Depending on how different the Mac the disks are designed for, you may or may not complete the install, may or may not be able to boot, may or may not be able to use various bits of the computer. If the disks are incorrect, they will lack drivers needed for your specific hardware. That could mean anything. if they are meant for a PPC Mac, things will go very badly wrong. If they are meant for a machine with very similar hardware but a different display, maybe things will work except the display - I'm not really sure. Basically, if you are not certain the disks are correct, don't use them. I suspect - though I'm not sure - that the wrong disks could prevent you from booting into single-user or target disk modes, for example. That would make your situation considerably worse than it is at present.

    Are you near an Apple Store? You might see if they could let you use a set of disks to reinstall if you visited them.

    if for some reason, i can boot and get the firewire picture, but not get my disk to show up on another person's macbook, is there something i am doing wrong, or is it just the fact that my hardware may not be sound. also, perhaps of note, it showed up once then i coudln't get to my User/anything else file, then i tried to eject it, then i canät see it anymore. but anyways now the disk utility doesnä work.


    any thoughts?

    This is when booted into target disk mode? You could try a different firewire cable and/or different firewire port(s) (if applicable). Otherwise, it should show up. I don't know if the other person is running a very old version of OS X, maybe it wouldn't recognise it - but then I don't think it would show up even once, of course... You could try restarting Finder on the other Mac. You could also try using Disk Utility on the other Mac and/or see if you can see it in Terminal.
    also, perhaps of note, it showed up once then i coudln't get to my User/anything else file, then i tried to eject it, then i canät see it anymore. but anyways now the disk utility doesnä work.

    Are you running Disk Utility from the other Mac? What version of OS X does that Mac have? In what way doesn't it work?

    In case nobody asked: do you have a current backup?

    Well my problem seems to be getting worse. I finally got the discs in the mail, and I attempted to re-install the OS with a slimmed version, so to fit in the 5 GB i had free. Omitting some fonts, some programs and some extras, it said it would install, and after checking the disks, it then failed. A couple of times. I then tried to install again, but on the select a hard-drive screen to install to, my hard drive either had the exclamation point indicating that it could not be installed to this volume, or it remained faded. I tried to repair the disk, using disk utility, however it returns and error to the extent of disk repair failed because of mounting problems. I have a backup copy of all my pictures and vital documents, so I was prepared to just erase the disk and start fresh, however any attempt to erase the disk was met with an "input/output" error, and I was not able to erase it.

    Now, it won't even boot from the disk, and it emits one long tone when I start it up, but it only does it once. When i hold down option, the cursor appears as if to allow me to choose what to boot from, but no drives, and no disks appear for me to choose.

    Nowhere near enough. You need a minimum of 15% or 5 GB free after the install, whichever is greater. Preferably 20%.

    Can you start up from the install disk? It sounds like hardware, but I am not really knowledgeable enough to say.
