I was able to perform the update on my Hackintosh via the Combo update. As ALWAYS, after the installer ran I got the "Installation Failed" message, but it was actually installed just fine. (BTW, anyone know why we get the Installation Failed messages when programs install just fine?)
My Rig:
Gigabyte GA-Z68X-UD3H-B3
Intel i5 2500K, 16Gb RAM, two (x2) MSI HD6870 Twin Frozr II with the X-Fire bridge connected.
I too had no audio after the combo update. I keep 2 copies of the AppleHDA.kext files. The original Apple one, and the modified one that has always fixed the issue. I re-installed the original AppleHDA.kext first using Kext Utility. Rebooted and had audio again, but not the correct ports. Then I reinstalled the modified (don't remember where I got them, had the kext for a long time now) AppleHDA.kext file and rebooted. Back to normal. 100% working with no issues. All the MoBo ports are working fine (i.e. Firewire, USB 3.0, USB 2.0, Audio, LAN, etc...). The system profiler sees both MSI HD 6870's just fine and has no issues with the X-Fire bridge in place even though OSX 10.8.5 doesn't use it. Lastly I repaired permissions.
Every combo update since ML came out has killed my audio, but the reinstall of kext files always fixes it fast. Usually if I have an issue its my video cards playing nice and I have to reinstall those kext's.

See this post in my Golden Build description.I'm running off GA Z77 UP5 TH and am concerned about losing my system with this update. Can anyone offer experience or a precise method particular to this board? My thanks extended,
