The only thing I can says is ... reinstall if it's not working.

 

On the other way, there's other flags you can try (npci=0 -v -f pcirootuid=0 ...)

Yeah currently doing that onto another HDD but had to recreate the boot usb as its gone corrupt :(

Knew i should have backed up  :lol: so im gonna get it going on the other hdd and experiment with the broken install see if i can bring it back to life, if not wipe that drive and mirror new install to that so i got 2 and then get rid of windows and use that 500gb as a data disk as windows now hates me and gone mega slow,

 

Will try those flags tho and get back to you:)

I have updated to Mavericks 10.9.2.

I have renamed my mach_kernel as mach_kernel_ok

I have made a backup of /System/Library/Extensions as Extensions.ok

I have updated with OSXUpdCombo10.9.2.dmg

After applying the update I have rebooted with the Niresh Mavericks USB Installer.

Then enter in Terminal and renamed the mach_kernel as mach_kernel_bad.

Renamed mach_kernel_ok as mach_kernel

Moved /System/Library/Extensions as  /System/Library/Extensions.bad

Moved /System/Library/Extensions.ok as  /System/Library/Extensions

 

Boot again with -v -x -f flags

After that repaired permissions with Kexts Wizard and Rebuilded System Caches.

Reboot again and that's all.

 

Regards  ;)

Ok, I have cocked up the update 4 times now. Can anyone find a good video guide or tell me in more detail?

 

Thanks
