fspkwonx86 Posted September 17, 2025 Share Posted September 17, 2025 (edited) Grab these and Install them: Kernel_Debug_Kit_26.0_build_25A5279m.dmg Kernel_Debug_Kit_26_build_25A353.dmg Go to: /Library/Developer/KDKs/KDK_26.0_25A5279m.kdk/System/Library/Extensions Copy AppleHDA.kext to the Desktop, Right Click Copy, Right Click Paste.... Using MyKextInstaller 4.2 it HAS to be 4.2..... Click Install Kext, and Select AppleHDA.kext, when it finishes asking you for the password a hundred times, it'll ask to reboot, when it reboots it'll say Update to macOS Tahoe Successful, asks you for your iCloud Password and when you Log in you will have working AppleHDA. Yes this is for the Build released on Sept 15th. As I can see Opencore, SimpleLoader, and the Newer MyKextInstaller why they don't all work I don't know... this is the only thing that does apparently..

#McFly Posted September 26, 2025 Share Posted September 26, 2025 Users who exclusively utilize the iGPU's HDMI audio, bypassing the motherboard's internal audio controller, are not required to disable System Integrity Protection (SIP) and can successfully boot with a Secure Boot model enabled in OpenCore. The necessary configuration simply involves injecting the hda-gfx property for both the HDA controller and the iGPU within the DeviceProperties section of the OpenCore config.plist. Consequently, the native AppleGFXHDA kext will be loaded as expected. <key>#WARNING - 1</key> <string>This is just a sample. Do NOT try loading it.</string> <key>PciRoot(0x0)/Pci(0x1F,0x3)</key> <dict> <key>hda-gfx</key> <string>onboard-1</string> <key>#your-layout-id-delete-me</key> </dict> <key>PciRoot(0x0)/Pci(0x2,0x0)</key> <dict> <key>#your-configuration-delete-me</key> <key>hda-gfx</key> <string>onboard-1</string> </dict> 2 Link to comment https://www.insanelymac.com/forum/topic/361691-applehdakext-macos-2600-25a354-guide/#findComment-2841327 Share on other sites More sharing options...
fspkwonx86 Posted September 28, 2025 Author Share Posted September 28, 2025 perfect that does apply to any user trying to use kabylake graphics chipsets only i think those use whatevergreen or tahoe may require whatevergreen even on supported chipsets itll work but has no identification Acceleration with no Identification Strings like your using Iris Plus 640 with X-Ram... im posting now the only other required addition for full functionality (basically) on an iMac 18,1 2017 - non retina is now 100% tahoe supported (basically) give or take FeatureEnabler... is we just freaking got Wifi Back 2 Link to comment https://www.insanelymac.com/forum/topic/361691-applehdakext-macos-2600-25a354-guide/#findComment-2841425 Share on other sites More sharing options...

I’m modifying OCLP to use on Tahoe — I just finished compiling everything and will start testing now, just waiting for Time Machine to finish. If everything works as expected, I’ll make a post afterward. 2 Link to comment https://www.insanelymac.com/forum/topic/361691-applehdakext-macos-2600-25a354-guide/#findComment-2842715 Share on other sites More sharing options...

I made a lot of modifications and had to stop for the last few days, my focus was on Wifi BCM and Intel, as no one has managed to make it work yet. Try using the laobamac mod.

(Chinese version, if you have difficulties, use a translator using your cell phone camera) laobamac-OCLP-Mod right now im actually on device-specific dsdt fixes (work cited multiple sources of allllllllll the little fixes that come before you even think about devices new and old cpus and what semantics it all appears as), and since i dont know if this laptop im using right now has the Intel HDA Jumper Pin for BIOS Unlock (Dell) I have to figure out if 1. All EFIs have a BIOS Block, they shift from 4/8/16MB Blocks and the Number of Regions that get flashed pretty basic, broken down into Keys i get that, Changing the Bitmap and running it against UEFIPatch to Unlock MSRs... I have to figure out how to Flash it though... I have an Intel Wifi that ITWLM works but the Bluetooth is the big question.... as for the iMac i have iMac 18,1 Non-Retina 2017 Kabylake running Tahoe and it runs Beutifully with your Broadcom Driver even the KDK Disk Update darwin-development.... I just shut debugging off and i can still do IOKit Level Kext stuff like its able to send a series of VERB commands and report which ones work using AppleHDA Hooking and this is all on Tahoe that its working 2 Link to comment https://www.insanelymac.com/forum/topic/361691-applehdakext-macos-2600-25a354-guide/#findComment-2843940 Share on other sites More sharing options...

BlueToolFixup.kext (2.7.1) I have to do something similar but hit a roadblock in the Touchpad/Trackpad of the Dell System, Alot of OEMs have their own BIOS 1. and Trackpads 2. well NOW atleast they do. so instead of voodooi2c voodoops2 im going to try VoodooRMI... and experiement if that works with getting the Intel Bluetooth working... and finishing my ACPI Works Cited , i figured out the trackpad it requires changing some method names its just unclogging the Device, Renaming some sections and then letting that do its thing with a proper plugin load order Edited November 21, 2025 by fspkwonx86 1 Link to comment https://www.insanelymac.com/forum/topic/361691-applehdakext-macos-2600-25a354-guide/#findComment-2844018 Share on other sites More sharing options...
