@atoniodapc

not sure you can just patch the binary for cx20590 support. i posted an appleHDA.kext i created based on 10.8.4 for the Lenovo T420. it has 3 or 4 modified/custom files defining custom platform and layout etc. generally need to replace AppleHDA in /S/L/E. 

 

see posts 

            #241             clover bundle + kexts used for Lenovo T420 

 

or             #216             for just the AppleHDA kext for 10.8.4 

 

            #161             from earlier in that thread - more detail writeup about the kext if interested.

 

Tnks ,

My Bootloader is Clover

i tried this , but it doesn't work

 

It seems that with a simple patch we can change the allocated VRAM:

 

53616d1366190331-unified-appleintelframe

sudo cp -r /System/Library/Extensions/AppleIntelFramebufferCapri.kext ~/Desktop/
sudo perl -pi -e 's|\x00.{1}\x10\x07\x00\x00\x10\x07|\x00\x??\x10\x07\x00\x00\x10\x07|g' ~/Desktop/AppleIntelFramebufferCapri.kext/Contents/MacOS/AppleIntelFramebufferCapri

Change the red ?? with the red number bellow to set the desired amount of VRAM:
10 = 256MB of RAM
18 = 384MB of RAM
20 = 512MB of RAM
30 = 768MB of RAM
40 = 1024MB of RAM
80 = 2048MB of RAM
