So I just went to turn on my macbook and it wouldn't start all the way.
It stays on the screen with the apple until a message pops up telling me I need to restart my computer.
There is a message in the top left corner of the screen that says:

Unable to find driver for this platform: "ACPI"
Debugger called: <panic>
and then there are a bunch of letters and numbers.

I restarted several times but still can't get passed the apple screen without the message popping up.
The last thing I did before I turned my computer off (other than check my e-mail) is install all the updates.

Please help!

Also, I'm not too sure what all my mac info is since I usually find that out using the computer, but it's a macbook that I purchased last Jan ('07).

    What you are experiencing are kernel panics. These are usually the sign of hardware problems or corrupted software.

    Do you have any third-party RAM in the computer?
    Do you have any USB or FireWire devices attached to the computer?
    Have you installed any third-party software recently, especially anything with drivers such as multi-button mice?

    Try starting with the Shift key down to turn off extensions.

    Sounds like a kernel panic :-x.

    Try booting into safe mode as seen here:
    http://docs.info.apple.com/article.html?artnum=107393

    then you could try and repair your disk permissions in disk utility under the utilities folder in your application folder.


    try that and then get back to us .

    I tried starting up in safe mode but no dice
    It still gave me the message to restart
    Also, the only screen I see is the apple one, the progress indicator never appears.

    I don't have any thing hooked up to my computer right now and the last thing I installed onto my computer was Skype a few days ago...

    See this article for discussion and possible solutions.
  • rasin810 Level 1 Level 1 (15 points)
    I read the article however I never moved my systems folder and I'm unable to start up my computer all the way to double-check

    My computer tells me to shut down almost immediately after starting it, I don't even make it past the screen with the apple on it.

    Usually means the system is hosed. You may try this:

    How to Perform an Archive and Install

    1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.

    Repairing the Hard Drive and Permissions

    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.

    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

    2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.

    3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.

    4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.

    5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.

    6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

    Note that if the hard drive is not OK and cannot be repaired, then you will have to reformat the drive and reinstall OS X from scratch.

    How do I use Disk Utility to repair the disk first?
    Sorry, I'm kind of slow when it comes to this computer stuff...
  • Kappy Level 10 Level 10 (253,225 points)
    The instructions were included in my previous message.
  • rasin810 Level 1 Level 1 (15 points)
    how do I boot from the disk exactly?
  • Kappy Level 10 Level 10 (253,225 points)
    Put the disc in the optical drive, restart the computer. After the chime press and hold down the "C" key until the spinning gear appears below the dark gray Apple logo.

    Which hard drive entry do I select? The top or the bottom?

    nevermind!
  • rasin810 Level 1 Level 1 (15 points)
    Ok, So I have to free up a lot of space to do this, like 10 GB and I was just wondering if I deselect certain packages, will I be able to install them later?

    Could I uncheck language translations and printer drivers or is that not a good idea?
  • Kappy Level 10 Level 10 (253,225 points)
    If you don't have sufficient space you can omit the language localization files, Asian fonts, and any printer driver families you don't need, but you should install the family for your printers unless you there's not driver for your printer in OS X. Here's the guide to included drivers: Printer drivers included with Mac OS X.

    If you can it would be a good idea to backup your personal data files, iTunes library, etc. to an external drive so you can delete them from the system volume until after you finish the Archive and Install. This will free up more disk space.
