Spoofing coffeelake was causing my screen to go black while using the computer, so I had to finally figure out how to get kaby lake to work again (it was fine on HS). The key was to realise that I needed to set the index of the framebuffer to get the port-number (as seen in ioreg) that's...

I have a similar system. I just got it working with the macmini8,1 smbios. Even sleep/wake works now! See https://www.tonymacx86.com/threads/framebuffer-patch-for-ga-z270n-hd-630-macmini8-1-smbios.266210/#post-1862402

Just got sleep/wake working! As I said above, my approach was to spoof a coffeelake framebuffer (since that's what the mac mini uses), limit the ports to 1 (since I only use displayport). You may have to experiment with the connectors configuration in fb patcher to get your screen to light up...

With the framebuffer patch below (generated using the wonderful fbpatcher), I get full support for my HD 630 + 4k dell over displayport. I used the 3e9b0007 platform id, patched to limit the FB ports to 1 (my mobo also has hdmi, but I don't use it) and the device id to 3e9b. Since the igpu in...

The usbports.kext is pretty neat and self-contained. No need for an additional SSDT. Before upgrading from HS to Mojave, I first tried to minimize my config. I do wonder why I had to switch from iMac18,1 (worked fine on HS) to iMac17,1. Probably something to do with AppleGraphicsDevicePolicy, as...

Thanks for checking! I started out using usbinjectall, but recently moved to the usbports.kext generated by FBpatcher.

I have a similar box, but using Kaby Lake i7 / HD 630 (no dedicated graphics). For me, that meant I had to switch to the iMac17,1 SMBIOS (took me a while to figure out!) Now 10.4.1 is working as well as 10.13.6. (Was using iMac 18,1 without issues on HS, but that broke KBL graphics accel on...

My experience is with HD630, but since they're relatively similar: have you tried sleep/wake without any running apps? For me, my system wakes fine more than half the time when chrome is not running, while it never comes back when chrome is visible. Some more details...

(And did you try swapping the antenna connectors around? I'm using that adapter and airport card and it works really well.)

I'm guessing the guc firmware is actually needed for proper power management. Last time I posted a link to somewhere my post never surfaced, so I'll just suggest googling for "guc firmware power management". The code in kblgraphics has two code paths, one referring to "springboard" (??? -- only...

Ah, hdmi seems to be less stable

Are you using DisplayPort (like me) or hdmi? Check out the bios settings I have in the readme of my gist. I have a feeling Render Standby being enabled may be part of it. Did you also drop the PegSsdt acpi table (assuming you're not using a separate graphics card)

Not sure how similar our systems are, but I have wake kind of working (sometimes the systems still locks up, and it never works when chrome is running). https://www.tonymacx86.com/threads/kaby-lake-i3-7100-hd630-graphics-is-sleep-possible.222638/#post-1550215

DP. (This and more info, like bios settings, in the README in the gist)
