I encountered the previous error using this EFI: Desktop HEDT Skylake-XW and CascadeLake-XW – Download available [here] (X299 chipset) And another error with this EFI: - Desktop Intel Core Ultra Download I don't know what to do. I thought it would be easy by copying your configuration, but it's actually much harder for me with this new MSI PRO Z890-P WIFI motherboard and the Intel Core Ultra processor. TROUBLESHOOTING I reached out to Kimi K2 for help, and this is the crazy list of things I now have to tackle 🥵🤕 ### Generating ACPI/USB Fixes for Your Hackintosh... From Windows! Great idea! Windows is perfect for preparing your OpenCore EFI, and there are **cross-platform tools** that work great on Windows. You'll be able to generate your SSDTs, map USB, and compile your `config.plist` without macOS. Here's the optimized workflow for Windows 10/11. #### Essential Tools to Download (All Free, Windows-Friendly) 1. **OpenCorePkg** (for compilation): - Download the latest release from [Dortania GitHub](https://github.com/acidanthera/OpenCorePkg/releases) > `OpenCore-1.0.1-RELEASE.zip`. - Extract to `C:\OpenCore\`. 2. **ProperTree** (config.plist editor): - Download from [CorpNewt GitHub](https://github.com/corpnewt/ProperTree/releases) > `ProperTree.zip`. - Launch `ProperTree.exe` (no install needed). 3. **SSDTTime** (SSDT generator): - [CorpNewt/SSDTTime](https://github.com/corpnewt/SSDTTime/releases) > `SSDTTime.zip`. - **Important**: To extract your DSDT from BIOS on Windows, use **RWEverything** (free, [rweverything.com](http://rweverything.com/)). 4. **USBToolBox + USBMap** (USB mapping): - [USBToolBox](https://github.com/usbtool/USbToolBox/releases) > `USBToolBox.zip`. - [USBMap](https://github.com/corpnewt/USBMap/releases) > `USBMap.zip`. 5. **MaciASL** (ACPI compiler): - [MaciASL](https://github.com/acidanthera/MaciASL/releases) > `MaciASL.zip`. It works on Windows! #### Step 1: Extract Your DSDT (BIOS ACPI Table) 1. **Download and launch RWEverything** (`RW.exe`). 2. Click **ACPI** tab > **DSDT** > **Disasm** (disassemble). 3. Save the `.dsl` file to `C:\OpenCore\DSDT.dsl`. - **Tip**: If RWEverything glitches, use **AIDA64** (trial version) > System > ACPI > Export DSDT. #### Step 2: Generate Your SSDTs with SSDTTime (From Windows) 1. **Launch SSDTTime.exe** (run as admin). 2. **Load DSDT** > Select your `C:\OpenCore\DSDT.dsl`. 3. **Check these essential SSDTs** (based on your ACPI errors): - ✅ **SSDT-PLUG** (CPU Power Management - fixes _INI) - ✅ **SSDT-EC-USBX** (Embedded Controller + USB Power - fixes UBTC/USBC) - ✅ **SSDT-PMC** (NVRAM - fixes RTC issues) - ✅ **SSDT-HPET** (Timer - reduces namespace lookup failures) - If AMD: ✅ **SSDT-RTC0-RANGE** (for RTC errors) 4. Click **Build and Install** > Save the `.aml` files to `C:\OpenCore\ACPI\`. #### Step 3: USB Mapping with USBToolBox (No macOS Needed!) **USBToolBox can scan USB ports directly from Windows**: 1. **Launch USBToolBox.exe** (as admin). 2. Click **Refresh** > It lists all your USB ports (XHCI controllers). 3. **Identify ports**: - **Internal** (trackpad, webcam, etc.): Leave **unmapped**. - **External** (keyboard, mouse, USB boot): **Map them** (check or rename). 4. **Generate USBPorts.kext**: - Click **Create Kext** > Save to `C:\OpenCore\Kexts\USBPorts.kext`. - **Limit**: Max 15 ports per controller (otherwise, add `XhciPortLimit: True` in quirks). **Alternative if USBToolBox fails**: Use **USBDeview** (NirSoft) to list VID/PID manually and create a custom kext. #### Step 4: Edit config.plist with ProperTree 1. **Open ProperTree.exe** > **File > Open** > Your `EFI/OC/config.plist`. 2. **Apply these fixes for your ACPI errors**: **Kernel > Add (Kexts)** - Add in this order: ``` 1. VirtualSMC.kext (download from acidanthera) 2. Lilu.kext 3. WhateverGreen.kext (fixes CVFO thermals) 4. AppleALC.kext (alcid=1 for MSI audio) 5. USBPorts.kext (your new mapping) 6. NVMeFix.kext (if NVMe SSD) ``` - **Settings**: `Enabled: Yes`, `Force: No`, `MinKernel: 19.0.0` (for Ventura+). **ACPI > Add (Your SSDTs)**: ``` Path: SSDT-PLUG.aml | Enabled: Yes Path: SSDT-EC-USBX.aml | Enabled: Yes Path: SSDT-PMC.aml | Enabled: Yes Path: SSDT-HPET.aml | Enabled: Yes ``` **ACPI > Patch (To fix specific errors)**: ``` # Fix UHC to XHC (USB errors) Comment: Rename UHC to XHC Find: [75544843] // UHC Replace: [58484300] // XHC Count: 1 Enabled: Yes # Fix CHGBS Battery Comment: Fix CHGBS to BTTR Find: [43484742] // CHGB Replace: [42545452] // BTTR Count: 1 Enabled: Yes # Disable broken thermal CVF0 Comment: Disable _TZ.CVF0 Find: [5F545A2E43564630] // _TZ.CVF0 Replace: [5F5448554D5F5F5F] // THUM___ Count: 1 Enabled: Yes ``` **Booter > Quirks**: ``` DevirtualiseMmio: True EnableWriteUnprotector: True RebuildAppleMemoryMap: True SetupVirtualMap: True ``` **Kernel > Quirks**: ``` AppleCpuPmCfgLock: True AppleXcpmCfgLock: True DisableIoMapper: True PanicNoKextDump: True XhciPortLimit: True // Important for USB ``` **NVRAM > Add > 7C436110-AB2A-4BBB-A880-FE41995C9F82**: ``` boot-args: -v keepsyms=1 alc=0x1e0 xhci=1 ``` 3. **File > Save** (ProperTree auto-validates). #### Step 5: Compile with OpenCorePkg 1. **Open CMD** (as admin) > Navigate to `C:\OpenCore\Utilities\OpenCoreConfigDebug.bat`. 2. Run: `OpenCoreConfigDebug.bat C:\Path\To\Your\EFI\OC\config.plist`. - It validates and reports errors if any. 3. If OK, copy your entire `EFI` folder to your bootable USB drive. #### Step 6: Test the Boot - **Plug your USB** into a **USB 2.0 rear port** (avoid 3.0 for initial boot). - **Boot** with `-v` (visible in OpenCore picker). - **Logs**: If you reach verbose mode, the ACPI `AE_NOT_FOUND` errors should drop by 80%. #### Quick Workflow Video (If You Prefer) Search **"OpenCore Windows setup"** on YouTube – tutorials like **SnazzyLabs** or **Dortania** show this exact process. #### If You Get Stuck on a Tool - **RWEverything won't dump DSDT**: Use **Universal BIOS Backup Toolkit** (free). - **USBToolBox won't scan**: Map manually with an online generator (search "USBPorts generator"). - **MaciASL glitches on Win**: SSDTTime auto-compiles them anyway. **Start with extracting the DSDT** – it's the foundation. Once you have your SSDTs + USBPorts.kext, your `UBTC`/`CHGBS`/`_STA` errors will melt away. If you have a specific MSI model, I can hook you up with a base EFI that's compatible! What are you tackling first? The DSDT or the USB mapping?

Hi Maldon, I'm still struggling a bit. Could you share your EFI folder with me? Which one are you currently using?

I'm still struggling with my installation. Which EFI folder do you use for this motherboard?🥵 I disabled everything related to Intel: Security Device Support, Intel Dynamic Tuning Technology, Intel Adaptive Thermal, Intel C-State, Intel Speed Shift, and Intel Turbo. But I'm still getting the same initial errors I mentioned in my first message

Do you keep all the Kext on the Kernel part for your config ?

No problem, I was just saying that in case you happen to have a custom ACPI file😁 Thank you, i really appreciate your help 🙏

Thank you it's ok but now I'm facing ACPI error, can you please share your ACPI files 🙏

Thank you for your quick response.😇

Hi Maldon, I really need BIG HELP please. 🧐🥵 Everything is almost working fine with the TAHOE setup linked above. I finally replaced my motherboard with the same one as yours — MSI PRO Z890-P WIFI — and installed the Intel Core Ultra 7 265K Arrow Lake CPU. Memory: JUHOR DDR5 16GB X 2 BIOS : 1.AA0 Now I'm facing a boot screen issue. Here's a screenshot of the problem — are you experiencing the same thing? I suspect it's due to the integrated graphics not allowing the dedicated GPU to take over during startup. How did you manage to get yours working? I mean, our configurations are nearly identical 😑PLEASE HELP Motherboard MSI PRO Z890-P WIFI ----BOOT Troubleshooting---- Here’s my previous configuration that was working before the change with TAHOE beta.. link above MB : MSI Z370 GAMING PRO CARBON ( MS-7B45 ) CPU: Intel(R) Core(TM) I7-8700K CPU @ 3.70GHz Memory Size: 24576MB G-SKILL Trident 8 x 2 + Corsair Balistic 8 x 0 Graphic Card - XFX LIMITED AMD Radeon RX 6750 XT Wifi adapter : AZUS FAST PCE-AC56 Dual-Band PCI-E Adapter 802. 11 ac Wireless-AC1300 5G-WIFI Ssd Drive: Sabrent Media SSD NVme 500GB Samsung NVme SSD 970 EVO 250GB Samsung SATA SSD 860 EVO 1TB

what kind of problems 😬

Salut, je ne sais pas combien ce la coutera pour l'envoi colissimo, il faut que je me renseigne sur le prix. je te tiens au courant, par contre je n'ai pas PayPal !

Hello everyone, Please, could someone guide me through the steps to perform a proper update to the latest macOS Tahoe beta? I’m still on one of the early beta versions and would like to update, but I’m hesitant as I fear breaking my Hackintosh, which was quite challenging to set up. My current version is a public beta, and I see that we’re now at the eighth beta. Every time I’ve tried upgrading from one version to another, I’ve had to reinstall everything. I imagine there must be a simpler way to update to a more recent version 🙏😇 UPDATE TAHOE

I live in Paris 🙏 and this answer is for Moishiteru. I still own the MSI graphics card 1070 TI, if you still want it you need to pay for a delivery 😂

hello finally I have get it work, thanks TAHOE

I need help. Could someone please reply? It's urgent. I don't want to keep the card if it's not compatible with Tahoe..😭
