Version 2

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 , see my post # 107 on insaneleymac see here: http://www.insanelym...-testing/page-6 .

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 .

Good Luck!
