Recently after updating to 10.9.4 everything seemed okay. However, soon after there was a safari, iTunes, etc update in which my hackintosh froze during the download/install. Upon rebooting both programs worked, BUT, now the computer screen will randomly turn black and acts as if it loses signal to the computer because it switches throughout the different input as if nothing were connected.

Can someone help me with this issue? I will try to get the -V list (am i remembering this correctly?) upon boot up to get the terminal error messages.

My Hackintosh specs are as follows...

- iMac 12,2
- CPU: Intel i7 2600k Sandy Bridge (Corsair H80i)
- RAM: 8GB G.SKill Ripjaw 1600
- Optical Drive: Sony Optiarc
- Case: Fractal Define R3
- Motherboard: Gigabyte Z68X-UD3H R3 (UEFI updated)
- System Drive: 128GB Samsung 830 SSD
- Storage Drive: 1TB Hitachi Deskstar
- Graphics: MSi GTX 670 OC (Kuhler 620)
- Power: Corsair TX750M
- Fans: B gears B Blasters

Below is my original Multibeast settings and how I originally installed OSX on my computer starting with ML 10.8.2. Since then I have installed the combo updates and reinstalled USB, TRIM, and audio drivers as recommended.

COMPONENTS


  • Gigabyte Z68X-UD3H-B3 Motherboard (UEFI BIOS)

  • MSI GTX670 (with custom bracket Antec Kuhler 620)
  • G.Skill Ripjaw (2 x 4GB) DDR3-1600
  • 128 GB Samsung 830
  • 1TB Hitachi HDD
  • Corsair TX750M
  • Sony Optiarc optical Drive
  • Fractal Design Define R3 Black w/ USB 3.0

Procedure:


  1. Update BIOS to UEFI (version U1H): Link

  4. UniBeast
    • Follow this tutorial: Link
    • Stop after completing steps 1 and 2.
  5. Boot from flash drive
    • I normally boot in verbose mode just incase (-v)
    • More info: Link
  6. Install Mountain Lion
    • Follow this tutorial: Link
    • Follow: “STEP 3: Install Mac OS X Lion”
  7. Complete initial setup.
  8. Run MultiBeast and select the following options:
    - You must select the "NullCPUPowerManagement" kext in miscellaneous
    - You must select GraphicsEnabler=No
    - DO NOT install "FakeSMC Plugins" an offending kext will hinder you from booting
    - For this build chose iMac 12,2 under System Definitions

  9. The installation will fail, so do the following...
    - Finder -> Go -> /System/Library/Extensions -> Delete "IOUSBAttachedSCSI.kext"
    - Next you will need to rename this offending kext -> /System/Library/Extensions/IOBluetoothFamily.kext/Contents/PlugIns/CSRHIDTransitionDriver.kext

    This may cause Bluetooth to not work properly but you can fix this later. Do the following in terminal to temporarily rename the kext so you can boot.

    Code:
    Type: cd /System/Library/Extensions
    Type: cd IOBluetoothFamily.kext/Contents/PlugIns
    Type: sudo mv CSRHIDTransitionDriver.kext CSRHIDTransitionDriver.kext.bak
    (give your password - the cursor will not move - there will be no feedback - just type the password and <Enter>)

    Type: cd /System/Library
    Type: sudo touch Extensions
  10. Install Multibeast again, this time it will work.
  11. Reboot and enjoy your hackintosh
 
any help?

maybe i should try deleting and installing safari and iTunes?
