A tool designed to simplify the creation of OpenCore EFI

1. Comprehensive Hardware and macOS Support
   Fully supports modern hardware. Use Compatibility Checker to check supported/unsupported devices and macOS version supported.

   Component	Supported
   CPU	Intel: Nehalem and Westmere (1nd Gen) → Arrow Lake (15th Gen/Core Ultra Series 2) AMD: Ryzen and Threadripper with AMD Vanilla
   GPU	Intel iGPU: Iron Lake (1nd Gen) → Ice Lake (10th Gen) AMD APU: The entire Vega Raven ASIC family (Ryzen 1xxx → 5xxx, 7x30 series) AMD dGPU: Navi 23, Navi 22, Navi 21 generations, and older series NVIDIA: Kepler, Pascal, Maxwell, Fermi, Tesla generations
   macOS	macOS High Sierra → macOS Tahoe

2. ACPI Patches and Kexts
   Automatically detects and adds ACPI patches and kexts based on hardware configuration.

   • Integrated with SSDTTime for common patches (e.g., FakeEC, FixHPET, PLUG, RTCAWAC).
   • Includes custom patches:
     • Prevent kernel panics by directing the first CPU entry to an active CPU, disabling the UNC0 device, and creating a new RTC device for HEDT systems.
     • Disable unsupported or unused PCI devices, such as the GPU (using Optimus and Bumblebee methods or adding the disable-gpu property), Wi-Fi card, and NVMe storage controller.
     • Fix sleep state values in _PRW methods (GPRW, UPRW, HP special) to prevent immediate wake.
     • Add devices including ALS0, BUS0, MCHC, PMCR, PNLF, RMNE, IMEI, USBX, XOSI, along with a Surface Patch.
     • Enable ALSD and GPI0 devices.

3. Automatic Updates
   Automatically checks for and updates OpenCorePkg and kexts from Dortania Builds and GitHub releases before each EFI build.

4. EFI Configuration
   Apply additional customization based on both widely used sources and personal experience.

   • Spoof GPU IDs for certain AMD GPUs not recognized in macOS.
   • Use CpuTopologyRebuild kext for Intel CPUs with P-cores and E-cores to enhance performance.
   • Disable System Integrity Protection (SIP).
   • Spoof CPU IDs for Intel Pentium, Celeron, Core, and Xeon processors.
   • Add custom CPU names for AMD CPUs, as well as Intel Pentium, Celeron, Xeon, and Core lines from the Rocket Lake (11th) generation and newer.
   • Add a patch to allow booting macOS with unsupported SMBIOS.
   • Add NVRAM entries to bypass checking the internal Bluetooth controller.
   • Properly configure ResizeAppleGpuBars based on specific Resizable BAR information.
   • Allow flexible iGPU configuration between headless and driving a display when a supported discrete GPU is present.
   • Force Intel GPUs into VESA mode with HDMI and DVI connectors to simplify installation process.
   • Provide configuration required for using OpenCore Legacy Patcher.
   • Add built-in device property for network devices (fix 'Could not communicate with the server' when using iServices) and storage controllers (fix internal drives shown as external).
   • Prioritize SMBIOS optimized for both power management and performance.
   • Re-enable CPU power management on legacy Intel CPUs in macOS Ventura 13 and newer.
   • Apply WiFi profiles for itlwm kext to enable auto WiFi connections at boot time.

   and more...

5. Easy Customization
   In addition to the default settings applied, users can easily make further customizations if desired.

   • Custom ACPI patches, kexts, and SMBIOS adjustments (not recommended).
   • Force load kexts on unsupported macOS versions.

1. Download OpCore Simplify:

   • Click Code → Download ZIP, or download directly via this link.
   • Extract the downloaded ZIP file to your desired location.

   

2. Running OpCore Simplify:

   • On Windows, run OpCore-Simplify.bat.
   • On macOS, run OpCore-Simplify.command.

   

3. Selecting hardware report:

   • On Windows, there will be an option for E. Export hardware report. It's recommended to use this for the best results with your hardware configuration and BIOS at the time of building.
   • Alternatively, use Hardware Sniffer to create a Report.json and ACPI dump for configuration manully.

   

   

   

4. Selecting macOS Version and Customizing OpenCore EFI:

   • By default, the latest compatible macOS version will be selected for your hardware.
   • OpCore Simplify will automatically apply essential ACPI patches and kexts.
   • You can manually review and customize these settings as needed.

   

5. Building OpenCore EFI:

   • Once you've customized all options, select Build OpenCore EFI to generate your EFI.
   • The tool will automatically download the necessary bootloader and kexts, which may take a few minutes.

   

   

   

6. USB Mapping:

   • After building your EFI, follow the steps for mapping USB ports.

   

7. Create USB and Install macOS:

   • Use UnPlugged on Windows to create a USB macOS installer, or follow this guide for macOS.
   • For troubleshooting, refer to the OpenCore Troubleshooting Guide.
