[GUIDE] Install OS X Mountain Lion on Samsung RF4XX/5XX/7XX Notebooks

Hey guys!

Many people have been pressing me for a guide, for installation of OS X Mountain Lion on their Samsung RF-series notebooks. Well, here it is. It is in essence, nearly the same as my OS X Lion guide, with the exception of MultiBeast configurations and a few others… So here goes the guide!


This guide is split into 3 parts: What You Need, The Install, and Work-In-Progress .



The Hardware:-

  • A REAL Mac or a WORKING Hackintosh, with minimum, Mac OS X Snow Leopard 10.6.8
  • An 8GB thumbdrive
  • A USB mouse and keyboard
  • A USB WiFi adapter, I recommend this one

The Software:-

  • A PAID copy of OS X Mountain Lion
  • The latest version of UniBeast for OS X Mountain Lion (v1.5.3) found in the tonymacx86 Downloads page
  • The latest version of MultiBeast for OS X Mountain Lion (v5.0.2) also found in the above-mentioned page
  • The Samsung RF4XX_5XX_7XX Install Files Pack-Mountain_Lion.zip file attached to this post


Now that you’ve gotten everything you need, let’s jump straight into the install, no more delays. Follow the next few steps to get OS X Lion installed on your system.

STEP 1: Preparing your UniBeast drive

  1. Using your Mac or Hackintosh, follow tonymacx86’s instructions to create your UniBeast drive. MAKE SURE YOU SELECT “LAPTOP SUPPORT” when you create your UniBeast drive. I really can’t emphasise this any more.
  2. Plug your Unibeast drive USB 2.0(BLACK) port on your notebook. Plug in a USB mouse as well. Boot up your laptop from your UniBeast drive.

STEP 2: Installing OS X Mountain Lion 

  1. Once you enter the installer, format your drive as GPT (GUID Partition Table), and create a partition formatted as Mac OS Extended(Journaled).
  2. After formatting, proceed with the install. The install will take around 20 minutes. Once the installation completes, reboot your laptop from the UniBeast drive, and select your newly-created OS X partition.

STEP 3: Setting up and finalizing your OS X Install

  1. Once you enter OS X, remove your UniBeast drive to make space for a USB keyboard. At the network prompt, select “My computer does not connect to the internet”. Everything else is up to you. Log in to your desktop. Remove the USB keyboard, and plug in the UniBeast drive once again. Leave it plugged in until step 12.
  2. You notice that OS X is now running at your notebook’s maximum resolution. In the Samsung RF notebooks, the Intel HD 3000 graphics processor is hardwired to be default, which OS X takes advantage of. Even without NVIDIA Optimus, the integrated graphics will still be the default processor-there’s no option in the BIOS to change this. So you cannot enable the discrete NVIDIA GPU, if you have one.
  3. Close any mouse/keyboard prompts that appear when you log in. To prevent such future annoyances, select System Preferences -> Bluetooth. Click on Advanced. Un-check the top two checkboxes.
  4. This step ONLY applies if you purchased the ASUS USB-N10 WiFi adapter. Without this adapter, your only choice for Internet connectivity is a wired Ethernet connection, which works out of the box. Open the Install Files Pack that you downloaded, and navigate to the Zips directory. Open 1-RTL8192SU_MacOS10.6_1079.zip and install the necessary files. Reboot your computer back to OS X.
  5. Plug in the ASUS USB-N10 Wifi adapter. Open System Preferences, and select Network to configure your wireless adapter. Click Apply, and close System Preferences. Open the Applications folder and look for Wireless Utility. This application configures and connects to your wireless network.
  6. THIS PARAGRAPH IS IMPORTANT. DO NOT MISS IT. Open the Zips folder you extracted before, and open 2-DSDTEditor_Mac.zip. Go to this site (you need to sign up first) and download the patch specific to your notebook model. Open DSDT Editor, and select File -> Extract DSDT. Then, go to Patch -> Open… from the menu bar. Select the text file that you just downloaded from the Olarila forum in the popup window. Then, a new popup window will appear, and click Apply. After that, from the menu bar, select IASL -> Compile. You will see a new popup window appear, which alerts you to any errors in your patched DSDT. If there are any errors, just click on Fix Errors. Finally, go to IASL -> Save AML as… and name your DSDT file as DSDT.aml, and save it on your desktop. For more information on creating and editing your own DSDTs, see this thread. REALLY SIMPLE!
  7. In the Zips folder, navigate to 3-VoodooHDA Zips. Open the 4-VoodooHDA-2.7.3.pkg.zip file, and install. DO NOT REBOOT. Navigate to /System/Library/Extensions, and look for VoodooHDA.kext. Copy to your desktop, and DELETE VoodooHDA.kext from /System/Library/Extensions. DO NOT MISS THIS STEP.
  8. Open 5-VoodooLoader_InstallerBETA.zip which is in the same folder, and install. Open the Applications folder, and look for VoodooLoader. Right-click, and select “Show Package Contents”. Open Contents, and go to Resources. Delete the VoodooHDA.kext you see there. Then, copy the VoodooHDA.kext from your desktop to the Resources folder. Enter your password where prompted. DO NOT REBOOT YET.
  9. Navigate to the Zips folder again, and open 6-Battery Mountain Lion.zip. You see two kexts there, copy them to your desktop. Use Kext Utility (Google it) to install these kexts to /System/Library/Extensions. DO NOT REBOOT YET.
  10. Download Apple’s OS X Mountain Lion 10.8.1 Client Update, and install. DO NOT REBOOT YET. Open MultiBeast and select these options:
    • UserDSDT or DSDT-Free Installation
    • Drivers and Bootloaders -> Drivers -> NullCPUPowerManagement
    • Drivers and Bootloaders -> Drivers -> PS/2 Keyboard/Mouse/Trackpad
    • Drivers and Bootloaders -> Drivers -> USB 3.0 – 3rd Party UNTESTED
    • Customisation -> System Definitions -> MacBook Pro -> MacBook Pro 8,1
  11. Launch Kext Utility to fix any wrongly-set permissions.
  12. FINALLY, reboot your notebook from your hard drive. You can remove the UniBeast drive now. Chimera should automatically kick in, and if you followed all these instructions correctly, you should see the OS X Mountain Lion login screen, without running into any problems.

STEP 4: Customisation and slight bug fixes

When you log in to OS X Mountain Lion, you see a small VoodooLoader window spring up, and close soon after. Then you may or may not hear an incredible whining sound, that can make you deaf, literally. This whining sound tells you that VoodooHDA works fine, and just that the plist values are set horribly wrong. To get rid of this whining, go to System Preferences, and you should see a VoodooHDA preference pane there. select it, and look for an iGain slider. Drag it all the way to the left. You have to do this every time you reboot, so to save time, go here to see a comprehensive guide on editing the plist files of VoodooHDA. Note that VoodooHDA isn’t in /S/L/E, and you have to Unpack the VoodooLoader application and look for the kext. THIS IS A VERY IMPORTANT RULE: TO EDIT KEXTS, ALWAYS COPY THEM TO THE DESKTOP. Copy the kext to your Desktop, and right click, selecting Show Package Contents. Open Contents, and open Info.plist. It is out of the scope of this guide to show how to edit the VoodooHDA plist file so go to the abovementioned link to see how to edit VoodooHDA.


The Samsung RF series of notebooks are decent enough for hackintoshing. However, there are a few pressing issues that we need to address.The PS/2 Keyboard/Mouse/Trackpad option in MultiBeast only enables the keyboard. I noticed that when booting from only UniBeast, without Chimera installed, both the keyboard and trackpad works, with no problem. However, after completing all the steps, you may notice you need a USB mouse.Secondly, the VoodooHDA Audio solution is only temporary- I’m working on enabling the built-in ALC269 chipset with AppleHDA. Updates coming soon. For more info on patching AppleHDA for the ALC269 chipset, see this link.Hackintosh and DSDT pros, please help in these areas. Your help will really be appreciated. Thanks a lot.
