https://github.com/acidanthera/opencorepkgA toolset for porting UEFI code to userspace and managing UEFI-based boot processes. Includes specialized drivers, hardware metadata decoders, and tools like GopStop for GOP testing, CrScreenshotDxe for UEFI screenshots, and OpenNetworkBoot for PXE and HTTP boot support.
libhelix-mp3 library. It is used for MP3 decoding within the OpenCorePkg ecosystem. The library is licensed under RCSL/RPSL.OpenCorePkg is an OpenCore bootloader accompanied by a development SDK. The repository includes a collection of UEFI support libraries designed to provide supplemental functionality for Apple-specific UEFI drivers.
Key capabilities provided by these libraries include:
EnableGop is a standalone GOP (Graphics Output Protocol) driver designed for EFI-era (~2009-2012) Mac Pro (4,1/5,1) and iMac firmware. It injects necessary OpenCore components into the firmware to provide pre-boot graphics support for non-natively supported GPUs.
Capabilities enabled by the driver:
ALT key.Requirements:
BootKicker.efi).Warning: This is a Beta release. Incorrect installation can brick your hardware. Always back up your main or GPU firmware before proceeding and ensure you have a reliable recovery method (e.g., SOIC clip and CH341A controller).
Staging directory contains experimental drivers that are not considered production-ready. These drivers are intended for testing or specific use cases but may lack stability or full feature support.FindSerialPort script is a utility used to locate PCIe serial ports on a system and output their corresponding paths. This is useful for identifying hardware paths for serial communication devices.The OpenCorePkg repository provides a wide range of specialized libraries for UEFI development, focusing on Apple-specific protocols, security, and system management. Key functional categories include:
OcAcpiLib (injector/patcher), OcAppleKernelLib (kernelspace injector/patcher).OcAppleBootPolicyLib (Apple bless protocol), OcFirmwarePasswordLib (Apple firmware password protocol).OcDataHubLib (DataHub configuration), OcSmbiosSmbiosLib (SMBIOS data), OcAppleChunklistLib (chunklist handling for DMG hashes).OcAppleDiskImageLib (DMG as UEFI RAM disk).OcConfigurationLib (OpenCore config deserialization), OcSerializeLib (PLIST deserialization), OcXmlLib (XML/PLIST reading), OcStringLib (string management).OcCryptoLib (AES, RSA, MD5, SHA-1, SHA-256).OcFileLib (supplemental I/O), OcVirtualFsLib (UEFI filesystem interception), OcStorageLib (resource storage abstraction).OcBootManagementLib (blessed-based boot management with UI), OcCpuLib (CPU feature scanning), OcRtcLib (CMOS access), OcTimerLib (TSC-based timer).OcGuardLib (sanity checking, overflow math), OcDebugLogLib (debug output redirection).OcMachoLib (Mach-O handling), OcPeCoffExtLib (EFI image management), OcPngLib (PNG decoding).OcDevicePathLib (device path management), OcDevicePropertyLib (Apple device property protocol).AppleEfiSignTool is an open-source utility used to verify digital signatures on Apple EFI binaries. It supports both Apple Fat binaries and standard PE images.
Key Capabilities:
-f option, the tool displays information regarding W^X (Write XOR Execute) and section overlap fixups.OpenHfsPlus driver implements HFS+ filesystem support including bless extensions.OcCompressionLib is a modified version of zlib (based on v1.2.13) adapted for smooth integration into the OpenCore bootloader. To use this library, you must include the specific header and source files listed in the [Sources] section of OcCompressionLib.inf and ensure the following modifications are applied:
OC_INFLATE_VERIFY_DATA macro for optimized performance.z_errmsg.AudioDxe driver provides improved audio support, specifically for Intel HD audio. Note that digital outputs such as HDMI are currently not supported.EnableGop driver is a standalone, firmware-embeddable driver designed to provide GOP (Graphics Output Protocol) support for non-native GPUs on EFI-era Mac Pro and iMac hardware.
