Question

I installed Mavericks on my laptop successfully. But, i got a problem on my graphics. My laptop is Lenovo G405s-7577, and the specification:

Processsor :AMD A8 5550 Quad Core

RAM 4 GB

VGA AMD HD8570M

Conexant Smart HD Audio with Dolby Advanced Audio v2

Wireless Atheros AR956x

LAN Atheros AR8172/8176/8178.

 

And, i can't connect to the internet with may wireless and LAN, my graphics is not working, also my speaker is not working, and working only if i plug my headset.

 

Any one can help me?

Thanks.

Remove all nVidia kext (see guide how to do it).

Start with PCIRootUID=0 -v

do you have VooDooHDA kext for sound? Use Slytherin to install it to get sound work. For wifi I doubt this card is yet not working but check google.

@wahidnr

1) Graphics Card (ATI 8750m) - Support almost non-existent

2) Wireless Card (AR956X) - No available kext

3) Sound (Conexant) - Install the Conexant Audio package with Slytherin

 

Your laptop should have integrated Intel Graphics, try focusing on trying to make that work rather than the ATI.

@wahidnr If you don't have integrated graphics (that was the last hope), your graphics acceleration isn't going to work. You will have a laptop stuck at a resolution of 1280 x 768 :(
