Apple posted update for new MBPs
Inside we have two new kexts (and some bundles for it), and these kexts have device ids of supported devices
AppleIntelHDGraphicsFB.kext – 0x00468086 0x00428086 (It is the framebuffer)
AppleIntelHDGraphics.kext – 0x00448086 0x00468086 (it is the accelerator)
These devids is for
0042 Core Processor Integrated Graphics Controller (clarkdale’s (desktop) core i3/i5 gpu)
0044 Core Processor DRAM Controller
1025 0347 Aspire 7740G
0046 Core Processor Integrated Graphics Controller (it’s probably arrandale’s (mobile) core i5/i7 gpu)
Good luck in trying these kexts!
