Read Instructions Carefully
OPEMU : UD2 , this is a BUG in the opcode a part of the AMD kernel .
The only way to fix the problem after an update , I have described several times
You simply need to do a Rollback of Sandbox.kext and System.kext and AppleMatch.kext and Corecrypto.kext from Mavericks 10.9.
Then repair the permissions and reboot your system . that's all!
Each Mavericks kernel has the same bug as all AMD kernel based on the opcode of Sinetek and Andy van Dijk .
As long as the error is not corrected, the rollback must be made after each update .
