OC-Little: ACPI Hotpatch Samples and Guides for OpenCore
Overview
OC-Little is a comprehensive resource for OpenCore users, offering ACPI hotpatch samples, guides, and fixes to enhance macOS compatibility on hackintosh systems. This repository, based on OC-Little by Daliansky, provides translated and expanded content, focusing on achieving a "Real Vanilla Hackintosh" experience while maintaining ACPI compliance.
Not an Installation Guide: OC-Little is not a guide for installing macOS. For that, refer to Dortania's OpenCore Install Guide. This repository provides supplementary guides, fixes, and explanations for hackintosh systems.
ACPI Compliance: OC-Little emphasizes methods that maintain ACPI compliance, avoiding techniques like DSDT patching, which deviate from a "Real Vanilla Hackintosh" experience. See this discussion on InsanelyMac for more details.
About OC-Little
OC-Little is a collection of ACPI hotpatches, binary renames, and guides for OpenCore, translated from Daliansky's OC-Little. It complements Dortania's OpenCore Guides and covers topics like ACPI basics, device enabling, USB mapping, graphics fixes, and more. While tailored for OpenCore, most SSDTs and techniques are compatible with Clover.
Translation Notes
Translation Process: Uses AI-based tools (DeepL, Google Translate) with manual copyediting for accuracy.
Restructuring: Organized into logical sections based on issue types, components, and methods.
Improvements: Rewritten confusing sections (e.g., ACPI, USB Port Mapping), added missing descriptions, and included new content (e.g., USB Port Mapping via ACPI, Chapters 7–14, and the Appendix).
Accuracy Note: As the translator does not speak Chinese, minor inaccuracies may exist.
