Hi,
I updates to 10.8.2 via combo updater, but couldn't boot past the gray startup screen, because of OemSMBIOS.kext. After replacing AppleACPIPlatform.kext with the old one from a previous post in this thread, my system booted without any problems.
Now, as I really don't like having legacy kexts on my system, I tried out various methods to allow me to keep the vanilla 10.8.2 AppleACPIPlatform.kext. The solution was quite easy and had a great benefit to it. I installed Kozleks branch of FakeSMC + optional Kexts for sensors: https://github.com/kozlek/HWSensors
Not only can I now boot with the original 10.8.2 AppleACPIPlatform.kext, without having OemSMBIOS.kext throwing an error, but I also get much more information from my hardware sensors opposed to the original FlakeSMC-Plugins from Multibeast. Furthermore a serial number is generated for my machine (so no problems with iCloud and Appstore) and VT-d can stay enabled in BIOS! This kexts should find their way into the next Multibeast update.
Using the kexts from Kozlek was a win-win for me Please only try at your own risk and backup your system before trying this. This worked great for me, but could kill your installation.
Updated using built in software update. After update I ran multibeast to reinstall ALC898 driver to regain audio.
System:
Gigabyte GA-Z77X-UD5H
Intel Core i5 3570k
Intel HD4000
Corsair Vengeance 8GB DDR3 1600MHz RAM
TP-Link Wifi Adapter (TL-WDN4800)
I got kernel panic after upgraded on my dell precision m4500 laptop from 10.8.1 (kp1.jpg).
I renamed AppleACPIPS2Nub.kext and ApplePS2Controller.kext in /System/Library/Extensions (kp2.jpg). Now my keyboard doesn't work and I cannot test anymore until I get a USB keyboard.
Could anyone help me to workround the AppleRTC issue.
I've seen a lot of people saying if they can't boot they can boot with -x and/or GraphicsEnabler=No
What happens if you can't boot? How can you get the system up and running to do recovery?
I've tried looking through the forums but it seems nobody has the same problem as me. I'm totally lost as to how to get this up and running.
My system just stops. It doesn't seem to be crashed as plugging USB devices in prints logs to the console. I'd just bought Mountain Lion and got it all running nicely when this update killed my machine
EDIT: There is no VT-D option in my BIOS. There is a virtualisation option which I have disabled to no effect.
