Lenovo T530 OpenCore 1.0.7 v1.0

Changelog

2026-02-05: Improved ACPI _OSI Handling, Tahoe-ready

• Implemented a new method for cleaner and more reliable _OSI handling on macOS → improves shutdown stability and overall system responsiveness.
• Updated ACPI tables to route OSI checks through the new OSDW method.
• Updated OpenCore and drivers to 1.0.7 nightly
• Updated Drivers and Kexts
• Tested with macOS 14.8.4 (23J319), 15.7.3 (24G419), and macOS 26.3 (25D122)

CONFIG Changes:

• ACPI/Add
  • Added SSDT-OSDW.aml
• Booter/MMIO Whitelist
  • Removed MMIO Whitelist entries → no longer required after OC debug bootlog analysis.
• Kernel/Quirks
  • Disabled DevirtualiseMmio → unnecessary after analysis.

Important

• Reset NVRAM after Deployment
• Apply Root Patches with OCLP in Post-Install to get working graphics acceleration (macOS 12+) and Wi-Fi (macOS 14+)
• Change hibernatemode from 0 to 25 (or 3) in Post-Install via pmset or Hackintool to enable hibernation! (More Details)

Caution

• DON'T install macOS Tahoe yet!
• DON'T update AppleALC.kext → slimmed kext
• DON'T update BrcmFirmwareData.kext → slimmed kext
• DON'T update VoodooPS2Controller.kext → The one by Acidanthera works worse than the original for this TrackPad!
• DON'T update VoodooSDHC.kext
• DON'T use YogaSMC.kext – it crashes the system on boot since it requires Acidanthera's version of VoodooPS2Controller which doesn't work well with the T530's TrackPad.
