I am using clover to inject graphic and hdmi devices. And my video ram is set to 32MB. Here is my config.plist.

View attachment config.plist

Does these kext patches still work in 10.11.x?

Thanks!
 
I suspect if it's a software issue?

I found many reports of the same KP log from users of real macbook.


Hi~

It seems HD4000 driver cause random crashes in 10.11.1.

I am using clover to inject graphic and hdmi devices. And my video ram is set to 32MB. Here is my config.plist.

Does these kext patches still work in 10.11.x?

Thanks!
 
You can remove boot arguments kext-dev-mode=1 (unless dual booting with Yosemite) and rootless=0 as neither of those are used in El Capitan.

The only thing I can think of to try is increasing your IGP minimum size and IGP aperture size. Though if it's a problem on real Macs too, I don't have high hopes.

While IGP aperture size can be set to 512MB, IGP min size should be matched to the ig-platform-id.

And 0x0166000a only allows 32mb.......

Changing it to other values make my machine fail to boot.

I found system report say it has 1536MB VRAM. Should it be 1024MB? How can I change this value?
