Morining to everyone,
I've partially solved the problem.
I reinstalled the OS again, not installing the VoodooTSCSync kext, as P1LGRIM said. Everything goes ok.
Then I've installed all the other drivers with multibeast, except for the ethernet one. Everything was fine again, also the ethernet was working, without installing its driver. However, after the reboot of the system (after having installed all the others driver using multibeast) the ethernet has not been recognised anymore !!!!
With this problem I also couldn't login into the apple store and iCloud, because "the identity of my computer could not been verified....." !!!!!
After googling a little bit, I've found a way: I've installed the ethernet driver. After the reboot the system could not boot anymore !!!!!!!! Another time !!!!!!!!
(The Ethernet driver I've installed was: AppleIntelIE1000e v 3.0.4.1a. My Ethernet is integrated in my motherboard, an Asus Saberthooth x79 - ntel® 82579V, 1 x Gigabit LAN Controller(s) )
I've tried other drivers too, but the system always didn't want to boot anymore !!!!!
Reading a little bit on internet, I found the solution for the problem of the "identity of my pc":
"Go into SysPrefs->Network and remove all interfaces, Apply, then remove /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist. Reboot, then add all your network interfaces back, starting with Ethernet."
Ok, this works !!!!!
Now I only have the problem of the boot. Going in verbose mode the problem is this:
[IOBluetoothHCIController][SearchFor TransportEvent........--MissingBluetooth Controller Transport!
A common problem, as I read on internet !!!!
However I tried with this solution found in another post:
"I solved the problem with the missing bluetooth controller transport with the following from InsanelyMac Legend rlf:
Boot -s. When you see the prompt "root:", then:
Type: mount -uw /
Type: cd /System/Library/Extensions
Type: mkdir intel_back
Type: mv AppleIntelHD* AppleIntelF* intel_back/
Type: touch ../Extensions"
But, after the first time, I always have to boot doing this:
Boot -s
Type: mount -uw /
Type: cd /System/Library/
touch ../Extensions
reboot
Isn't there a way to do that automatically???
Can I fix this problem????
Thanks a lot for your precious help.
Have a nice day
Enrico
