v1.0.6-rev2: Sleep Freeze Fix & EFI Variants

This revision is a critical update to v1.0.6, specifically addressing system stability during the Sleep/Wake cycle on Ryzen 5900HX and clarifying the EFI versions.

1. Critical Fix: Wake Freeze (ForgedInvariant vs. CpuTscSync)

The primary issue in the previous build was the system completely freezing/hanging shortly after waking from sleep.

  • The Cause: The ForgedInvariant.kext was failing to correctly synchronize the Time Stamp Counter (TSC) across the Ryzen 5900HX cores upon wake. This desynchronization caused the macOS kernel to panic or hang.
  • The Solution: Replaced ForgedInvariant.kext with CpuTscSync.kext.
  • Result: CpuTscSync forces a hard synchronization of the TSC immediately upon wake, completely eliminating the system freeze. Sleep/Wake is now reliable.

2. EFI Versions Explained

This release includes two distinct EFI configurations:

EFI-OC-NOMOD (Standard)

  • Description: The standard OpenCore implementation.
  • Recommended For: Most users who want maximum stability and a vanilla experience.

EFI-OC-MOD (Experimental)

  • Description: Uses the "OpenCore Mod" (No ACPI) variant.
  • Features: Fixes the Blue Screen (BSOD) and fix others issues when dual-booting with Windows or other Oses.

4. General Cleanup

  • Cleaned SSDT, kexts.
  • Cleaned up config.plist boot arguments.
