I'm getting installation failed from using the combo updater provided above. I've tried to repair permissions and everything, and it says that some of them will not be repaired. Haven't tried through the app store yet.
Thanks for getting back! I've got good news......problem SOLVED!!!
Just wanted to post solution for UD5 X79 board updated from 10.8.4 to 10.8.5
After much headache and help from thanos4 its working again - thanks thanos4!
Maybe this will help someone else with the X79 board?
Ok here it goes -I did a fresh install of 10.8.5
BTW it should be noted my GTX 650ti card was in the far right slot closest to the CPU. Also have 6 core 3930K CPU. Not sure what video card others use or what slot they have it in, and or cpu but below boot flag worked for me:
I had to use bootflags in USB by pressing space bar then enter "-v -x GraphicsEnabler=No npci=0x3000 cpus=1"
Once in desktop I ran the below Multi Beast 5.5.1 settings for theUD5 X79 with GTX650ti:
1: Under Customization checked GraphicsEnabler=No since I could not boot properly without using that boot flag
2: Instant Menu
3: Easy Beast
4: audio 898 (without DSDT)
5: hnak for network
6: trim enabler 10.8.3 (if you have ssd - I do have a OCZ Vertex 4 and love it)
7: appleACPIplatform rollback-to 10.8.1 Rollback
8: ssdt options-sandt bridge core i7
9: Adjust org.chameleon.Boot.plist in the string in the <string>darkwake=0 </string> line to include "npci=0x2000"like so <string>darkwake=0 npci=0x2000</string>"
10: I added generic usb kext that stork recommends via the kext utility tool from post 2.
11: Did a repair disk permission in disk utility.
now everything works flawlessly ....sound...network. ..ssd - I have RME fireface 800 audio hardware so I dont mess with junky on board audio anyway
Just FYI here is my working org.chameleon.Boot.plist in case it helps some other poor fool update the UD5 X79 board to 10.8.5:
