Many issues with post-installation on Samsung NP740U3E

Hi all

 

I've managed to get a working OSX installation, albeit one with many issues to fix. Your help would be immensely appreciated!! My full laptop specs are in my signature.

 

My current set up is a UEFI dual boot on my Samsung NP740U3E-A01SG laptop using Clover, with which I boot Windows 8 and Mavericks 10.9.4. I made my USB installed based on vanilla Mavericks from App Store and then installed Clover on the USB's EFI partition. 

 

I also understand that it would be difficult for you guys to help me with so many problems at once, so I have listed them down in priority.

 

The most pressing issue now is the graphics. It would display artifacts which persist until I do a reboot, and the artifacts would appear on random. Sometimes I would be able to boot just fine with perfect graphics, resolution and colour. Other times it would be a mild distortion, so I can still do work on OSX. Yet other times, the artifacts would be so terrible that nothing intelligible can be made out on the screen.

 

Fixes I have tried to no avail: injecting EDID into Clover's config.plist as well as the fix described here: http://www.insanelymac.com/forum/topic/208410-fixing-scrambledstretched-or-wrong-resolution-laptop-display-problems/

 

2. Ethernet. Best I have achieved so far is to have Ethernet connected but unable to get IP address or internet connection. IP address becomes self-assigned and does not result in internet connectivity. Fixes tried: installing Realtek RTL81xx.kext

 

3. Touchpad. I have installed ApplePS2ElanTouchpad.kext but it is still buggy. When I do a click-drag operation, the pointer will hang and I would have to use the USB mouse. Keyboard however works fine. If I uninstall the ApplePS2Elantouchpad kext, both laptop keyboard and touchpad will not work, requiring the use of USB mouse and keyboard.

 

4. Sound. Cannot adjust volume nor play soundtracks.

 

5. Sleep. I read that NullCPUPowerManagement breaks sleep, but is there a way around that?

 

Less important issues to be resolved are:

 

a. Bluetooth remains switched on without the ability to switch off.

 

b. Wireless. Since I am running an Intel wireless card which I know it is unsupported, I have ordered from Ebay a Broadcomm DW1510 to be installed. So I will further update on this point in 3 weeks when it is delivered.

 

Kexts which I have installed: (they are from OSXLatitude Extended Driver Package[EDP] for NP740U3E)
