mac-fish Posted April 3, 2017 Share Posted April 3, 2017 Hey guys, I'm back to trying to set up my hack after getting tired of yosemite and being too lazy to upgrade for a year now. So I've updated clover to the latest version and got the kexts required for sierra and installed it onto a new partition. It boots and works quite well already, however I can't seem to get the IntelHD driver for Capri to work. On yosemite this worked fine with the igp platform id 016...03 in the clover plist. However this does not seem to work on Sierra anymore. I have verified that I am using the same boot flags. The issue is that the driver seems to load, however i just get a blackscreen on the LVDS as soon as LoginWindow would start. (can't test other outputs right now) So how could this happen? Did the definitions of the connectors according to the platform id change? Do i have to try different platform IDs all over again? The relevant info about the hardware: Generic Ivy Bridge laptop with i7 3720QM GTX675M and Intel HD4000 (Optimus, The GTX675M is disabled by DSDT patch, however in sierra there are some ACPI errors on boot, might be that the ACPI table format is incompatible? it works fine in yosemite...) I've also tried RehabMan's latest FakePCIID and its Intel HD module, but no luck. Any ideas?

mac-fish Posted April 3, 2017 Author Share Posted April 3, 2017 The graphics config will be similar but a lot of Clover users experience this black screen issue after updating to 10.12.4. It seems you'll have to update Clover. Chameleon/Enoch systems do not suffer this black screen issue... Hey Hervé, thanks for the hint, however in the meantime I figured it out myself The problem wasn't clover (It booted just fine as I mentioned, it worked without InjectIntel also). Also the backlight was on when the framebuffer loaded. The problem was I forgot to patch AppleIntelFramebufferCapri.kext, which is necessary for laptop LVDS to work. I applied the same method as described in a post from 4 years ago and it works fine with the Sierra driver as well. (here's the guide, there are many others as well though http://forum.osxlatitude.com/index.php?/topic/2945-guide-for-enabling-vga-and-hdmi-in-intel-hd4000-gpu/ ) Thanks anyway and I hope this will help someone out.
