Macbook Won't Start, Unable to Find Driver

No, don't use their disks it will make things much worse. Can you start your computer at all? You can back up your files on flashdrives, disks, whatever you have. Send for your disks. Using disks not meant for your computer will make it more than likely inoperable. I need to re-read your first post and I'll post back. Ok, aimili?

Can you get to your Utilities folder? If yes, find disk utilities, find disk permissions, run this.

Post back with answers,

Hello again, try to boot from a safe mode, I'll give you directions:

To start up into Safe Mode (to "Safe Boot"), do this:

Be sure the computer is shut down.
Press the power button.
Immediately after you hear the startup tone, press and hold the Shift key.
Tip: The Shift key should be held as soon as possible after the startup tone but not before.
Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).

Post back with results and we'll try something else,

Hi, if this fails try resetting the Pram to get a screen, more directions: Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

I'm also having this same:

panic (cpu 0 caller 0x0039bc83) unable to find driver for this platform.

It happened while I was updating a friends intel macbook pro from 10.4.6 (I think) to 10.4.11 or whatever the latest combined update was on the apple software updater. I have tried to repair permissions, start up in safe mod, reset pram, with no luck. I assume the answer will be to reinstall the OS, the problem is this particular laptop was purchased a year ago and was a demo model from a large chain store, and my friend didn't receive the OS install discs. Now he's up the creek with out a laptop!!! HELP!!

Me too. (Sorry: my english... is...)

I have a macbook: it happens the same: that aimili's "panic message" with the ACPI, (panic(cpu 0 caller 0x003A8DBD)).

Besides, my cd-unit don't works (it crashed some months ago, so I can't use my "install disc"). This is a very disgusting situation. Please, help. The only option I see right now is to run other OS, but there is no other OS installed in the computer. I found this option pressing and holding the "option" key (after press the power button). Then I can see two pictures of two disc representing two OS: Mac and... and... windows (!!! ????). I don't understand how this was possible.

Please, I need more information about how to re-start/reset/etc. the computer without the cd's.

thanks!!

Hi, and a warm Welcome! 🙂

You'd get more help by starting your own New Topic.

The two OSes with Option Key are due to somebody installing something like Boot Camp, but if Windows wasn't installed also it won't help.

Does clicking on Windows do anything?

If you have another Mac around there are options, but please staart a New Topic...

http://discussions.apple.com/thread.jspa?messageID=6960388&

No, when I click in windows the computer says windows is missing (I never installed a different OS).

Now I'll test all this keys:
cmd-.
cmd-opt-p-r
cmd-opt-n-v
cmd-opt-o-f
d
n
r
t
z
ctl-cmd-shift-power
shift
cmd-v
cmd-s

thanks!
