Finally I managed to boot my system to HDMI (DP is also working). I have attached my ioreg and config.plist below.

Hello guys, I am back... hope you all are doing well. May I know if there is anything I can test for now?

Good news is that my Framebuffer@3 is back, but the port-number is showing 0x0 but not 0x7, so now my system keeps rebooting. Guess I need a revised "port 0x7 to HDMI" patch to make it work again. Please see my attachment below 6.zip Appreciate if you can help on this again. Hopefully it...

Thank you RehabMan for your time and support. Much appreciated.

Tried to capture below dmesg. Does it help? *** sudo dmesg | grep IGPU [IGPU] Will fallback to host-side scheduling if graphics firmware fails to load [IGPU] Scheduler Tail Coalescing Enabled. [IGPU] Scheduler Tail Coalescing Enabled. [IGPU] Chose to use graphics firmware based on platform...

Okay, so I used Xcode to: 1. remove MatchOS and MatchBuild fields 2. remove old "4 displays" patch which has problem 3. verify both new "4 displays" & "port 0x7 to hdmi" patches ok 4. save config.plist Then rebooted with "-f" boot arg, then rebuilt cache, then rebooted again. Sorry to tell but...

Tried "-f", rebuilt cache again and rebooted, still black screen You mentioned that there might be something wrong in the config.plist Would you please take a look at my post #30 "4.zip"? Thanks.

I am using Clover R4035 but unfortunately I couldn't see the "boot without cache" option according to your FAQ. So I tried 2 things: 1. In Clover, I chose "Boot without injected kexts", then rebuilt cache through command line and rebooted 2. In Clover, I added "-f Kernel=mach_kernel" as boot...

To be exact, I did the following: 1. Disabled the problematic "4 displays" patch in Clover configurator 2. Added a new patch for AppleIntelSKLGraphicsFramebuffer you described above 3. Saved config.plist 3. Rebuilt cache by sudo touch /System/Library/Extensions && sudo kextcache -u /" 4...

1.zip was captured when injecting an invalid IntelGFX value during the boot process (so no graphics acceleration) 2.zip was captured when booting Verbose (black screen on HDMI display but able to enter the OS, so I captured using another PC via VNC) Looks like AppleIntelFramebuffer@3 no longer...

Hi RehabMan, I need your help again please. I updated my system from 10.12.3 (fully functional with graphics acceleration) to 10.12.4 via App Store yesterday. Once the update was done, my PC kept rebooting indefinitely. I could only break into the system by disabling ig-platform-id injection...

Hurray!!! It works like a charm!! Thank you so much RehabMan!

>>You should probably remove the patches you have for the framebuffer and start over with that process... Same result. DP works but still not HDMI. >>You should try other ig-platform-id values, different SMBIOS. Tried all different options available for Skylake in Clover 4003 but no luck...

That's weird. I could see the entire boot up process on the HDMI display until it was about the load the desktop. I also tried to connect my LCD TV but got the same result. When I logged in to it via VNC, the graphic response was the same as a fresh install without hardware acceleration. Is...

Please find the attached debug.zip I captured that when HDMI was the only connection. Looks like the acceleration driver was not loaded, and when I opened "System Preferences" => "Displays" only two options are there : "Scaled" => "1280x1024" & "1024x768" Thanks.
