Hi!

I have a Sony VAIO SVJ202.
It's a HM76 chipset, Ivy bridge.
CPU: i5 3317U
Mem: 6GB
Audio: Realtek ALC275
Video: HD4000 1600x900, Rev 09
Net: Wi-fi Centrino, LAN - Unknown Realtek

I've installed El Capitan using Clover.
Kexts used on the moment: FakeSMC.kext
Patched DSDT for CPU.

Boot options:
SMBIOS: Tried Macbook, Macbook Air, Mac mini

The problem is in integrated video card, it shows up only 5MB Vram and video is working glitchy and buggy.
I red everything related to this issue...
