[SOLVED]Mountain Lion 10.8.1 Update: still waiting for root device

Gigabyte P67A-UD3P-B3 Rev 1.1

Just upgraded 10.8 to 10.8.1. Appears 2 problems - first one with AHCI drivers, second - with PCI.

Sulution in my case: (suppose ML installed on MacPartition, replace with your own):

0. Boot unibeast - run Terminal, run /Application/Safari.app/Contents/MacOS/Safari, download attachment to /Volumes/MacPartition/System/Library/Extensions, Command-Q Safari.

sh$ chroot /Volumes/MacPartition

1. Replace AppleAHCPIPort,kext and IOAHCIFamily.kext from 10.8 backup (previously patched for 10.8, from this View attachment Archive.zip).

sh$ cd /System/Library/Extensions
sh$ rm -fR /System/Library/Extensions/IOAHCIFamily.kext
sh$ rm -fR /System/Library/Extensions/AppleAHCIPort.kext
sh$ unzip Archive.zip

2. Remove npci Kernel Flags from /Extra/org.chameleon.Boot.plist (if exists)

sh$ nano -w /Extra/org.chameleon.Boot.plist

... <key>Kernel Flags</key>
<string>npci=0x3000 darkwake=0</string>

replaced with

... <key>Kernel Flags</key>
<string>darkwake=0</string>

3. Reboot with unibeast, press any key while chameleon logo, choose MacPartition. Do permission repair and cache rebuild with Kext Wizard

4. Reboot from HDD. Mine works.

Goodbye!

Mountain Lion 10.8.1 Update: still waiting for root device [RESOLVED]

Thank you so much for this!
My Mac didn´t boot after 10.8.1 but now its working again

So far this fix has made my previously unbootable install on a GA-Z68Z-D3H-B3. I have not updated to 10.8.2 - yet. I'm going to try that tonight. I'm keeping my fingers crossed that it will still work.

I cannot tell you how much I needed this fix. I've reinstalled so many times and tried so may things that I was ready to just give up and buy a new motherboard. Many thanks!!!!

Progrand, thank you a thousand times!
i had a still waiting for root device on 10.7.5 after having used MultiBeast migration tool!
i was ready to reinstall and i just tried your kernel flag darkwake=0 and it booted really fast!
You saved me from hours of troubles (but i know that i'll manage to create another mess )

Thanks so much!

I did the same thing but from an installation of SL on another partition of my HD (cos i'm a noob and couldn't find the right comands for the terminal)

Worked a treat

I just used the kext files [IOAHCIFamily.kext, AppleAHCIPort.kext] from this post and repaired permissons--using Kext Helper b7 and Kext Utility. I also installed Chimera 1.11.1. I looked at org.chameleon.Boot.plist using Chameleon Wizard but didn't use <string>npci=0x3000 darkwake=0</string> as this wasn't present in my file and I wanted to reboot to test 1st. I'm thinking it was the kexts that fixed my problem with my 10.8.2 clone as the original drive I cloned from never booted so fast even tho it was also an SSD.

THANK YOU!!!!!!!!!!!! I tried EVERYTHING ELSE. I can't thank you enough. I looked all over, tried a lot of different methods. This was fast and easy.

Yes!
This needs to be stickied somewhere.
Perfect, working install now, 100% boot from HDD with everything working
Thank you poster!
