[GUIDE] Installing Snow Leopard 10.6.8 on Wortmann Terra 4440

1 post in this topic

Recommended Posts



About the system

The Wortmann Terra 4440 has a Clevo M7X0SU motherboard with onboard NVIDIA 9300M GS (256mb) graphics card. It has a Realtek RTL8187b USB WLAN card built in and a Synaptics Touchpad. I've been struggling a bit until I found out how to update to 10.6.8 properly, but heres my solution.


What you get

If everything goes fine, you'll have a 10.6.8 Snow Leopard installation with fully working graphics and audio, a WLAN driver and multitouch gestures on trackpad.


What you need

- SnowLeo 10.6.0 distribution DVD

- Combo update to 10.6.7

- Normal update to 10.6.8

- WLAN driver from here

- Touchpad driver from here


1. Preparing the computer

First, enter your BIOS menu and set SATA AHCI mode enabled.

Tip: If you cant find the AHCI option, look for a option called "Installed O/S". Set it to "VISTA". Now there should be an option "SATA Mode Selection", set this to AHCI.


2. Installing the base system

Boot from the DVD. Go to Utilities -> Disk Utility and create a Mac OS Extended (Journaled) partition on your hard drive. Then close Disk Utility.

Continue the setup, select the partition you just created and click Continue. In the next view click on Customize. A window will pop up with default selections. Keep them and select the following in addition:


System Patches/
Notebook Patches/


Install and reboot your computer.


3. Update to 10.6.7

Install the combo update but don't reboot!

Go to /System/Library/Extensions/ and delete the NVEnabler.kext.

Reboot with "-v -f" flags.


4. Create 10.6.7 extension backup

Open /System/Library/ and create a copy of your Extensions folder.


5. Update to 10.6.8

Install the update but don't reboot!

Go to /System/Library/Extensions/ and delete all the GeForce***.kexts and the NVDA***.kexts.

Open System Preferences -> Chameleon -> Peripherals and tick GraphicsEnabler.

Now copy the following files from your 10.6.7 extensions copy into the Extensions folder:




6. Repairing extensions permissions

Open OSX86Tools from the /Applications/TOOLS/ folder.


- Set Extensions permissions

- Clear Extensions Cache

- Clear User Application Cache

- Clear System Application Cache

- Touch Extensions Folder

and click on Run Selected Tasks. When finished reboot your computer.


7. Installing the WLAN driver

Unpack the WLAN archive. Copy the RTL8187Bl.kext to /System/Library/Extensions/. Then install the UI.pkg and the StartUpItem.pkg. When done repeat step 6.


8. Installing the Synaptics Touchpad driver

Unpack the Touchpad archive. Copy the two kexts to /System/Library/Extensions/ and the Trackpad.prefPane to /Library/PreferencePanes/. When done repeat step 6.


9. Get better audio driver

If your audio rustles or makes strange noise, get the newest VoodooHDA from here.


10. Have fun!

Now things should work fine. If you still have problems, feel free to ask me :)
