Yeah that’s been saving my butt So I installed Sonoma again then used Chris1111’s EFI and used my update SMBIOS and I’m getting a kernel panic

I need set my TDP to 253w or consume go to 350w+ and crash. After that just run fine with XMP on 6800mhz or 7000mhz.

Keep going, you'll get there eventually. A good tip is, when you have a good booting system, copy the bootable EFI to the EFI Partition of a spare USB Drive so that if/when you make changes and have a panic like a boot loop as you described, that USB Drive will rescue your system to a bootable state again. Good luck.

@Slice I have make VodooHDA in github source 4 years ago https://github.com/chris1111/VoodooHDA-Code

@chris1111 Thanks. That is similar to @droples suggestion here. I haven't tried it, but I'm sure it would work. I'm going to test again when OC 1.0.0 is officially released. Thanks again.

Maybe a temporary solution Did you try to use only boot file from OC 0.9.6 to OC 1.0.0 EFI duet simply replace it If it work You are booting to OC 1.0.0 after Duet Init -

We have sources of VoodooHDA and can add here all we want. We just should know what namely.

tks i'll take a look at https://anuragbhandari.com/coding-tech/fixing-headphone-jack-in-ubuntu-20-04-1755/ looks like linux as sof support in kernel. if it's so macos as very low chances to work this tool is nice look at the screenshot this is the default config that the sof driver creates now where does it place the config file... this is a linux discussion about this dmic thing https://bugzilla.kernel.org/show_bug.cgi?id=201251

Hi downlord I totally agree with you about the amazing job done by Tluck could you please share the package for t420 installed on Ventura? best regards

guys only use -allow3d if you wanna test something or see some crashes

@chris1111 Thanks . I have been setting FixupAppleEfiImages since here, but it didn't work for me and I still needed to use OC 0.9.6 legacy boot. I'll try again after OC 1.0.0 is released. EDIT: I have always required HfsPlusLegacy.efi on my HackBookPro6,2 since I created the Open Core solution for it. Since OC 0.9.7, I have assumed that I'm doing something wrong, but never took the time to debug and just reverted to OC 0.9.6 legacy boot.

When I use the -allow3d along with the commands above, the screen stops at the below. WhateverGreen igfx: @ FOD: Failed to route function the function getDisplayStatus WhateverGreen igfx: @ (DBG) platform is snb 0 and list 0XFFFFFF7FAC812C30

I just tried your modified WhenverGreen without the -allow3d flag and it allows me to boot without the blackscreen issue on 14.4.1, framebuffer is enabled, if using 8a71, you get 2048MB, commands below -v keepsyms=1 debug=0x100 -wegdbg igfxfw=2 The Blackscreen after Sleep issue is still there, i have my correct efis configs on usb's, so i use the internal ssd efi for testing, it doesnt actually enter sleep

Ok so I I updated my SMBIOS on Big Sur to 15,2 and was able to get the Sonoma installer after doing so. I remade the installer using chris111’s installer then replaced the EFI made with the installer with my updated EFI. I’m installing right now. Will report back soon. 🤞🏽 edit installed fine. Now I have to get WiFi to work. edit added kext BrcmFirmwareData BcrmPatchRam3 RealtekCardReader RealtekCardReaderFriend wifi not working edit added kext AirportBcrmFixup adding that kext makes the boot time longer Still no luck with WiFi edit removing 5 kext and installing OCLP edit resulting in boot loops

Hello I have X79 nonatree, e5 2650 v2 8 cores 16 thread Works only with cpus=1 both in Big Sur and Monterey, even if turnning of HT in bios, it runs better. I have removed all unused CPU Try all possible work around here Cpustscsync maybe broken on macOS Monterey · Issue #1676 · acidanthera/bugtracker (github.com) Tried CpuTscSync.V1.5.3, CpuTscSync, VooDooTSC, TScAdjustReset kext , ResetTSCAdjust.efi, with no luck, 1. either KP or reboot loop on Monterey 2. system free before logon screen on Big Sur I think it is still TScSync problem on Big Sur Userspace Issues | OpenCore Install Guide (dortania.github.io) Can you please have a look at my attached EFI with pached DSDT inclusive cpus-1-EFI-X79-2650-v2.zip

I have little experience with internal MIC <string>0x90a70130</string> -- analog Mic <string>0x90a6e140</string> -- digital Mic May be you want to patch also Node 27 to join to input 9?

@jalavoui I imported the scheduler and TGL DMC-related patches from the most recently uploaded NBlue to WEG and applied them. And, the part that calls the solveRequest or routeRequest function for getGPUInfo and _CSR_PATCH uses the SYSLOG syntax to output a log to check whether it was applied properly. // kern_igfx.hpp const unsigned char tgl_dmc_ver2_12_bin[] = { ... }; const long int tgl_dmc_ver2_12_bin_size = sizeof(tgl_dmc_ver2_12_bin); ... class ForceCompleteModeset: public FramebufferModifer { ... public: // MARK: Patch Submodule IMP const uint8_t *_CSR_PATCH_B0plus; const uint8_t *_CSR_PATCH_AX; void init() override; void processKernel(KernelPatcher &patcher, DeviceInfo *info) override; void processFramebufferKext(KernelPatcher &patcher, size_t index, mach_vm_address_t address, size_t size) override; } modForceCompleteModeset; KernelPatcher::RouteRequest request("__ZN16IntelAccelerator10getGPUInfoEv", getGPUInfo, ogetGPUInfo); if (patcher.routeMultiple(index, &request, 1, address, size)) SYSLOG("igfx", "[TGL+] getGPUInfo: Functions have been routed successfully."); else SYSLOG("igfx", "[TGL+] getGPUInfo: Failed to route functions."); // TGL_DMC_ver2_12.bin static const uint8_t f9[] = {0x83, 0xbf, 0x9c, 0x0c, 0x00, 0x00, 0x00, 0x74, 0x1f, 0x4c, 0x8d, 0x35, 0x7c, 0xab, 0x0e, 0x00, 0x41, 0xbf, 0x8b, 0x0c, 0x00, 0x00}; static const uint8_t r9[] = {0x83, 0xbf, 0x9c, 0x0c, 0x00, 0x00, 0x00, 0x74, 0x1f, 0x4c, 0x8d, 0x35, 0x7c, 0xab, 0x0e, 0x00, 0x41, 0xbf, 0x88, 0x18, 0x00, 0x00}; static const uint8_t f9b[] = {0x48, 0xff, 0x05, 0xed, 0x28, 0x0b, 0x00, 0x4c, 0x8d, 0x35, 0x06, 0x79, 0x0e, 0x00, 0x41, 0xbf, 0x91, 0x0c, 0x00, 0x00}; static const uint8_t r9b[] = {0x48, 0xff, 0x05, 0xed, 0x28, 0x0b, 0x00, 0x4c, 0x8d, 0x35, 0x06, 0x79, 0x0e, 0x00, 0x41, 0xbf, 0x88, 0x12, 0x00, 0x00}; KernelPatcher::SolveRequest solveRequest = { "_CSR_PATCH_AX", this->_CSR_PATCH_AX }; KernelPatcher::SolveRequest solveRequest2 = { "_CSR_PATCH_B0plus", this->_CSR_PATCH_B0plus }; if (patcher.solveMultiple(index, &solveRequest, 1, address, size) && patcher.solveMultiple(index, &solveRequest2, 1, address, size)) SYSLOG("igfx", "[TGL+] _CSR_PATCH: Functions have been routed successfully."); else SYSLOG("igfx", "[TGL+] _CSR_PATCH: Failed to route functions."); this->_CSR_PATCH_AX = tgl_dmc_ver2_12_bin; this->_CSR_PATCH_B0plus = tgl_dmc_ver2_12_bin; KernelPatcher::LookupPatch patch { &kextIntelICLLPFb, f2, r2, sizeof(f2), 1 }; patcher.applyLookupPatch(&patch); KernelPatcher::LookupPatch patchb { &kextIntelICLLPFb, f2b, r2b, sizeof(f2b), 1 }; patcher.applyLookupPatch(&patchb); KernelPatcher::LookupPatch patch2 { &kextIntelICLLPFb, f1, r1, sizeof(f1), 1 }; patcher.applyLookupPatch(&patch2); KernelPatcher::LookupPatch patch3 { &kextIntelICLLPFb, f9, r9, sizeof(f9), 1 }; patcher.applyLookupPatch(&patch3); KernelPatcher::LookupPatch patch3b { &kextIntelICLLPFb, f9b, r9b, sizeof(f9b), 1 }; patcher.applyLookupPatch(&patch3b); Test 1 - NootedBlue : Disabled - WhenverGreen : Enabled - IGPU Device Properties : Injected (Platform ID : 0x8A5C0002) - boot-args : -v keepsyms=1 debug=0x100 -wegdbg - macOS Version : macOS Ventura 13.6.5 (22G621) Result : Booting was successful, but graphics acceleration did not work.

Can someone please check if I modified WhateverGreen correctly? WhateverGreen.zip WhateverGreen-Sources.zip

@Slice please need little help to last post, thank you!🙏

i added the bytes to sonoma from the kexts you send hope it loads for you shl628 the tgl dmc bin is still a test (i think my code it is not well implemented). but you forgot to add _CSR_PATCH_B0plus part the firmware loop log is just a hack to show apple firmware message updated whatevergreen with sleep patch at this stage i have 2 goals: - framebufer load and avoid black screen (might need connector swap patch for some displays because if on frame zero it hangs the display with backlight calls) - sleep working using internal disk (might need dsdt.aml sleep patch) WhateverGreen.kext.zipWhateverGreen-master.zip

i really hate this pin config thing your changes gave a valid input device sof linux code seems to make 2 DMIC input sources this is a laptop. better focus on internal mic only ?

DMIC devices ? i'm still not sure if a special firmware is need just for the microphone device

I am not familiar with your machine and I don't know if your machine is the same as @chris1111 machine. I suggest you test his EFI Folder (attached in my previous post) on a USB Drive by booting off it and see what result you get. The GitHub link I included above has a few example EFI Folders for the HP Elitebook 840 G4 that you can also try but will need updating to latest files and kexts. If you put your machine 'HP Elitebook 840 G4' in the GitHub search bar, you will see some example EFI Folders. @chris1111 EFI Folder seems to have the latest updated files and kexts. Good luck.

Hi @lorys89 thank you for your help. So I did exactly as you told, and I noticed that when I installed your ALC plug fix the hissing noise totally disappears. Then if I boot the computer to macOS with the headphones jack already plugged I have no hissing noise but the audio is behaving kinda weird ( small echo, music louder than voices and stuff). If I then unplug the jack and replug it the hissing noise reappears but way quieter than original, like 10% of its original intensity, but apart from that, the audio is behaving normally. What I've also noticed is that when no audio is played for like 10 -20 sec or so, a small pop is heard and then no more hissing. The noise reappears as soon as I play some noise or sound. It's like the pin changes its power state then resumes. But I don't understand why after a wake the change in power state fixes the hissing noise. What does your script do actually? Maybe I have to tweet some coefficients specific to Acer.

It was actually very laborious work: I was trying different releases of Nooted Red one by one and finally found that right one. You can find plenty of releases in Actions but you never know which one will work with your machine. I tried the same with Sonoma and what works on Ventura it doesn't boot Sonoma. Finally I was able to boot Sonoma with acceleration as well but I am not happy with that because there is plenty of lags and freezes. It is simply unusable.

@eSaFis there anything I should mess with cuz I don’t have touchscreen?
