when i had an upgrade from 10.9 to 10.9.2 i got "opemu ud2 error" even though i made a back up of my "sandbox.kext", "system.kext", "Apple Match.kext", "corecrypto.kext" and even downloaded a working 10.9.2 kernel for my hackintosh and after upgrade finished then i boot into windows partition replaced all the backed up files and replaced the kernel then boot back on osx with flags like -x -v -f -F but all this didn't help me and i ended up in some sort of error atlast i had to do a complete re-install. Now i'm on 10.9 and want to upgrade to 10.9.4 with no error can any please provide all the steps necessary for this upgrade to work successfully on my pc.
