https://sourceforge.net/p/intelgraphicsfixup/svn/8/#diff-3 To anyone who was having issues with WebKit video playback for media with DRM protection on 10.12.4, I forked the original IntelGraphicsFixup project created by vit9696 and submitted a change to the original code which hooks into the...

Has anyone experienced such a thing on Skylake Graphics? When the 10.12.4 update released, I have had issues with video playback within Twitter, YouTube, etc within Safari. It freezes my display entirely for about 0.5 seconds, every 2-3 seconds until I quit Safari/WebKit altogether. Then...

On 10.12.4, there are issues with playback within Safari namely Twitter videos and content that is DRM protected. Anyway to fix this? IntelGraphicsFixup and Shiki are only for Haswell GFX, although the issues they seem to fix are similar in nature.

Solved. Found that in physical NVRAM that the variables were actually stored there, although NVRAM wasn't writable from OS X. Used dmpstore to remove all NVRAM variables with the OS X GUID found from the dump and AppleBacklight finally read the emulated backlight-level NVRAM variable to set the...

Thanks for this thread! After finding that IntelBacklight.kext did not work in the 10.12.4 update, I went for the AppleBacklight injector route and patched my ACPI tables. I created an SSDT-PNLF.dsl file with my PWMMax data, and the external references from SSDT-IGPU, as attached below. After...

Just a quick question Has anyone been able to boot the Apple Logo with a HiDPI resolution? The problem in this case is not with having a HiDPI resolution after second stage boot and login but rather with having the resolution set at the bootloader level. What happens on my machine is that it...

I can confirm issues happening with updating to 10.12.1. In /Library/Updates there is a FirmwareUpdate, FullBundleUpdate and macOS10.12.1.pkg. If I run all three installers individually it spits out that there are other additional components needed to complete installation and doesn't perform...

So, update to this situation. I ordered this machine from Newegg Refurbished much cheaper than the original price and it was supposed to come with a QHD resolution (Model no. HP Spectre x360 4193-dx GOLD). I found that it did not come with a QHD 2560x1440 resolution but rather a standard FHD...

I also tried updating to the 10.10.6 beta and this issue seemed to persist. As far as ig-platform-id goes I wish it was, I've tried the only other ig-platform-id that corresponds to my GPU 0x19160002 and it didn't solve the issue. Any more information that I can provide to you? Everything else...

I decided to give this issue a break, because this was flooding this thread. However, I applied all the "common patches" All the following recommended patches in my ACPI tables are applied "Fix _WAK Arg0 v2" "HPET Fix" "SMBUS Fix" "IRQ Fix" "RTC Fix" "OS Check Fix Win 8" "Fix Mutex with...

What would constitute necessity for patches in my ACPI tables.... from what I have gathered on your guides and threads is that these patches are essential for power management and proper device configuration. Battery Status PNLF GFX0 -> IGPU LPC HECI -> IMEI (simple rename of the device) SSDT...

Here is log when the WindowServer starts up and does arrive... if this helps ********** Bootstrapped Creating a default store:1 SpotLoc:(null) SpotVerLoc:(null) occlude:0 /Volumes/Windows Jun 27, 2016, 5:55:38 PM networkd[160]: -[NETInterfaceManager updateInterfaces] nwi_state_copy() returned...

With the changes suggested, I was able to get significantly faster and more consistent boot times but on some boots the WindowServer refused to arrive (black screen with cursor). Here are the files requested with the changes that you suggested AddHDMI_8000000 was disabled but then removed from...

AddHDMI_8000000 was already set to false, but I removed it from my plist. I use Clover to inject them but that's fine... some kexts have a library dependency i.e. IntelBacklight and VoodooHDA and that is why I put them in SLE. But... how does this relate to my issue?

Here is what you requested... Note I am not using AppleHDA and using Skylake (no AICPM load)

Intel HD GPU's generally have a GOP driver available so I presume that it wouldn't be related to that. But JUST in case, I did that, and right as I started up, the window server didn't arrive... hmm. It just takes a couple of boots to get it finally loaded correctly

No, since I'm only using UEFI loaders to boot up, I disabled the CSM module/Legacy Support... is that supposed to set to enabled?

I've tried IntelBacklight and verified that it was loading... And it didn't resolve the issue. I tried the FakePCIID_Intel_SKL_Graphics + FakePCIID + 0x1912 device id and that didn't help. I also tried the only other ig-platform-id that was for my GPU 0x1960002 (using 0x1960000) and on some...

After setting up Clover correctly I have solved the shutdown/restart issues. I won't say ACPI because an issue has arisen on my end. I went back to this thread because I posted about an issue I was having with specifically HiDPI resolutions... but it seems that the result of the issue is...

First, of all I would like to thank anyone who made this thread, because I was able to successfully get HiDPI resolutions working on my machine. However, I have experienced such a peculiar issue after getting it working. On my HP Spectre x360, I have tested many times and every single time the...
