kernel panic missing driver

My roomate was trying to do a software update on his macbook pro, and was restarting his computer when the following error occurred:


panic (cpu 0 caller caller 0xffffff800e059241): "Unable to to find a driver for this platform: \"ACPI\".\n"0/SourceCache/xnu/xnu-2050.20.9/iokit/Kernel/IOPlatformExpert.cpp:1 548


Debugger called: <panic>

Backtrace (CPU 0), Frame: Return Address


(bunch of hexadecimal addresses here)


BSD process name corresponding to current thread: Unknown


Mac OS version:

Not yet set


Kernel version:

Darwin Kernel Version 12.2.1: (Date here)

(more stuff here)


This error persists with restarts. I tried safemode, it will not work. I started into the mac hardware check, and ran a regular scan (not extended), which showed no problems with hardware. So, I assume the missing driver is the only problem. I booted into recovery mode and repaired the disk using disk utility and then tried to reinstall the OS, but it said something like "there is not a licensed OS on this computer". I figure he has to somehow reinstall the OS from recovery mode to fix the missing driver issue, but I'm not sure how to do that. There is no apple support centers nearby, and the college tech support can be a pain, so if I can help him fix it by myself that would be nice.


EDIT: I just remembered he did mention his computer has been a little slow the past couple weeks, but I'm not sure if that's related to this issue.

Hi!


I tried doing the hardware check and it shows "There might be an issue with a memory module. Reference code PPM004"


On the bottom of the screen it says your Mac will start in recovery mode and when I click "Get Started" it again goes to the reboot loop and gives a random kernel panic error (most of the times.. otherwise it just reboots).


Can you please help me with what should I be doing? I went to the local apple service center and they asked me to replace my logic board worth around $700. This was before I tried the hardware test myself. I obviously don't want to shell out that much. In any case thank you for your solution.

Yes, and now everything seems to be working properly. Here's what you need to do


1. Shut down your computer (probably need to force shut down, so just hold down the power button until it shuts off).

2. Turn on the computer and press the D key to boot into Apple Hardware Test, and scan your hardware. If you've already done this and determined its not a hardware problem (like I did) then skip this step. Turn off the computer.

3. Press the power button to turn it back on, but immediately after you press the power button press command + r to go into recovery mode.

3. From here you can go into the install OS option. You need an active internet connection to do this. Make sure you can access a wifi network or have an ethernet cable (you can launch safari and try a random website to make sure you have internet). Then you should be able to reinstall the operation system.


After the computer has finished downloading and installing the operation system, it should automatically restart and be working properly. All your files and stuff should still be there.

Steps:


1. Do you want to save your files? You have to reformat your laptop in order to use it again.

2. You open your lower case, buy the screws that you need. BE VERY CAREFUL when you're about to take out your hard drive. I would suggest that you get a screw set so you'll have all the screws that you need in this process.

3. Buy a SATA HDD Enclosure. I think the size of MacBook Pro's hard drive is 2.5 so you should get that one. You also need a another Mac for you to retrieve your files - Windows won't be able to see it.

4. COPY everything that you want.

5. Go to Recovery Mode, Install OS X. Then if it won't work, you go to torrent sites look for "Yosemite Bootable" I think it's a 7GB file so make sure to have a 16GB around. If that's done downloading, download TransMac. Your torrent should come with a instructions on how to copy the file to the USB. After, press alt/option button i think for you to boot your Mac. 😀 NOTE: It's going to be like brand new so this is where the files from your hard drive comes in. Goodluck!
