Typical boot failture after 10.8.2. update troubleshooting.
Boot in to safe mode (-x), your system should boot this way if you're having this crash
Open Terminal, and type "sudo mv /System/Library/Extensions/FakeSMC.kext/Contents/PlugIns/OemSMBIOS.kext /Users/youraccountname/" (replacing youraccountname with the appropriate account name )
Still in Terminal, type "sudo diskutil repairpermissions /" followed by "sudo kextcache -system-caches" (or repair permissions and update kext caches in any other way you prefer)
Reboot.
For Radeon 6xxx users.
-x
- We see a white screen. Turn sleep mode, wake up.
- Move OemSMBIOS.kext as above
- Profit!
How to restore the sound, see the upper thread.
above opinion may be correct soultion. but I de-assembled OSx machine.
