Lenovo T490 OpenCore 0.9.7 v3.0

Changelog

2023-11-24: Optimized HDMI handshake and other improvements

• Updated OpenCore to 0.9.7 (commit c65fb5b)
• Updated Drivers and Kexts
• Tested successfully with macOS Monterey to Sonoma 14.2 beta 3
• ACPI
  • Deleted SSDT-EXT3-LedReset-TP, because a) it does not work and b) YogaSMC fixes the pulsing Power Button LED after wake.
• CONFIG
  • ACPI/Patch
    • Added _PTS to ZPTS(1,N) and _WAK to ZWAK(1,S) renames because SSDT-PTSWAK and SSDT-EXT fixes actually require them so that the “Else” portion of the construct is executed if macOS is not running! All other T490 EFIs overlooked this!
  • DeviceProperties
    • Changed Device-ID of the Intel HD 630 spoof
    • Added Key disable-agdc property to Framebuffer-Patch → Disables Apple Graphics Device Control (AGDC) → Drastically reduces handshake time when connecting an external display via HDMI. Becasue AGDC causes issues on HDMI when using device-id spoofs.
  • Kernel/Add
    • Re-enabled YogaSMC. The previous issue (High CPU spikes) were caused by Intel Power Gadget’s EnergieDriver.kext which is no longer compatible with macOS 14.2+. So uninstall it, if it’s still present on your system!
• KEXTS:
  • Replaced itlwm.kext. The previous version didn’t work in 14.2 b3

NOTES:

• For deployment, follow the instructions on my repo
• Don't update the following Kexts:
  • AppleALC
  • itlwm
  • IntelBluetoothFirmware
  • VooodooSMBus (for now)
