Unable to find driver for platform: ACPI

I'm getting this error message: 'panic(cpu 0 caller OX0039C213): Unable to find driver for this platform "ACPI", overlaid on the kernel panic screen at startup.
I can't reboot into safe mode. In single user mode and verbose mode, the same error message appears and I can't type anything after it does.
This happened after I HAD a kernel panel, booted into safe mode, uninstalled recently installed applications (norton antivirus and stuffit) and deleted items from library/startupitems.
i then restarted to see if it would work normally, but now i can't even boot into safe mode.
i'm posting all of this from the windows partition of my macbook, which works fine.
HELP! my macbook is (sigh) not even 2 months old.

Hopefully someone else can be more helpful than I. "ACPI" is Windows technology. So the problem is in your installation of Windows (maybe the Mac foundation for it, I don't know).

This is almost certainly a software problem, and in the worst case, you can fix it by starting over with a clean install of OS X.

  • Time Machine restore fail: "Unable to find Driver for platform ACPI"

    After restoring a recent Time Machine backup of a 2010 MacBook Pro Snow Leopard system, I'm getting boot errors like
    panic(cpu 0 caller 0x5591cb: "Unable to find driver for this platform: \"ACPI\".\n"@/SourceCache/xnu/xnu-1504.7.4/iokit/Kernal/IOPlatformExpert.cpp:1389

    I'm re-installing using the Utilities menu on they grey (Snow Leopard) system DVD that came with the MacBook Pro I'm trying to restore. I'm definitely not using a Leopard DVD, which is something I know can cause problems.
    I've managed to restore from a non-Time Machine clone of my drive, but I now no longer trust my Time Machine backups. They are fine for restoring the odd user file, but seem to be broken or missing something crucial that means that my Time Machine backup is useless for restoring an entire system, which is something it should be capable of.
    Am I missing something obvious? Any suggestions?

    Hi Linc, thanks for your reply!
    In case I wasn't clear, I'm not reinstalling after restoring, or reinstalling the OS.
    Restoring my system from TM leaves me with an unusable system that kernel panics immediately on boot. My workaround is just to ignore TM and restore from a different kind of backup (a clone made with SuperDuper, as it happens).
    I think it would be a bit generous to Time Machine to call this a "workaround"! Time Machine doesn't work for me.
    Has anyone ever solved the problem of full restores of their TM backup leaving them with a system that has this problem?

    Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with networks that require any kind of authentication other than a WPA or WPA2 Personal password.
    When the Mac OS X Utilities screen appears, follow the prompts to reinstall the Mac OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac didn’t ship with Lion, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
    Don't install the Thunderbolt update -- it's defective.

  • HELP! "unable to find driver for this platform: 'ACPI'."

    I was updating my Macbook Pro's software today the standard way and when/after it was installing the latest Mac OS X, my laptop shut off and now it won't boot up. A screen comes on that says "you need to restart your computer..." (which i did, but this message keeps popping up). on the same screen, it says stuff like panic: unable to find driver for this platform, debugger called, and displays all these numbers and letters. i don't know what is wrong or how to fix it. did my computer crash when installing the updated software/platform? PLEASE HELP!

    mrb1568:
    If I may put in just one work of caution. Mac OS X: About the Archive and Install feature explains the procedure for the installation option. However, although you can choose to save your settings and preferences, and although all third party apps in the Applications folder are saved, as well as your Users Folder, the article starts out by suggesting that you backup. That is because if anything goes wrong, as you already know it can, you can likely lose all your data, or if it can be rescued, not without cost and a lot of time.
    If you don't have a reliable, up-to-date backup I suggest that you use SuperDuper to clone the entire HDD to an external HDD. You can do that by using Firewire Target Disk Mode and connecting an external HDD to the host computer.
    Good luck.

  • I need serious help! 'computer is unable to find driver for this platform'

    i was just manually upgrading my OS X 10.4.7 mac mini to OS X 10.4.9 when halfway through the upgrade installation the computer froze and i had to reset it.
    now everytime i turn on the computer it comes up with an error message saying:
    panic(cpu 0 caller 0x0039C213): Unable to find driver for this platform: "ACPI"
    the only option it gives me is to restart the computer which doesn't help.
    can anyone please tell me how i can fix this?

    Well. I think you have only two option left:
    Archive and Install: will re-install OS X preserving users and files.
    Re-install 10.4.9 Combo Update: In order to do this, you either need another Mac running Tiger and capable of starting in FireWire Target Disk Mode and a FireWire cable, or an external bootable HD.
    If you have another Mac that supports FireWire Target Disk Mode, you can proceed as follows:
    In the working Mac (the Target machine) download the appropriate 10.4.9 Combo Update (PPC or Intel). Leave it on the Desktop. Do not run it.
    Follow the steps of this article.
    Once your Mini has booted from the Target machine disk, run the 10.4.9 Combo Update, selecting as the destination of the install the Mini's Hard Drive.
    If you have a bootable external Hard Drive, (with OS X installed on it) boot from it (hold the Option key at startup), download the Combo Update and install it to the internal HD.
    If you don't have a bootable external HD, you can still re-install the Combo Update booting from the Tiger install disk, and using an USB thumb drive (sometimes it may need to be formatted as HFS), following this cumbersome procedure.
    Good Luck.

  • Kernel Panic: Unable to find driver for this platform

    So, my 1 GM RM, 1.5 GHz Powerbook G4 (15 inches) has been behaving wonderfully lately. Until, this morning, it locked up -- as it sometimes does -- after inserting a 3rd party SATA card and waking it from sleep.
    This is normally not a problem. A reboot gets things back on track. Not today. The reboot stayed on the grey screen with the white apple logo. I tried booting off of a Disk Warrior CD and an OS X 10.4 install DVD. I go this kernel panic:
    Unable to find driver for this platform: "PowerBook5,6".
    But...and here's the best part...if I boot into target disk mode and hook the computer up to another similar Powerbook we have, the similar PowerBook boots fine using my drive.
    So, it seems to be a hardware problem with my PowerBook. Any ideas on how I narrow it down?
    Thanks,
    Gary

    Glad you found your problem. Our kernel panic on our 15" G4 is a bad logic board. $500+ to fix it. Just found out yesterday.

    power book not loading (error: unable to find driver for this platform) help

    That usually happens when trying to install Mac software intended for Intel-powered Macs (made in 2006 through present) on a PowerPC mac like teh powerbook (made before 2006).
    You post is a little cryptic, however. We may be of further help if you can tell us:
    <> the PowerBook's processor type (G3 or G4) and the Mac OS version, both available by doing "About the Mac" from your Apple menu.
    <> what program and its version your were trying to run and/or install.

    I just updated my software, but seems my macbook got an error of unable to find driver for this platform..

    Did you try more than once? If so:
    Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair
    When the recovery menu appears select Disk Utility. 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 click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
    Reinstall Mountain Lion or Mavericks
    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X
         Note: You will need an active Internet connection. I suggest using Ethernet
                     if possible because it is three times faster than wireless.
