Lenovo T490 OpenCore 1.0.1 v2.0

Changelog

2024-06-16: macOS 15 Compatibility, new USBMap.kext

I've noticed that Bluetooth was no longer working in macOS 14.5 when using the USBMap.kext. Since BT works fine when injecting ports via ACPI, I recreated the USBMap.kext and also mapped the ports of the Docking Station I have (turns out it has hubs for USB 2 and 3).

Bluetooth doesn't work in macOS Sequia 15.0 Beta (24A5264n) yet but this is because the required kexts haven't been updated by the devs yet.

• OpenCore
  • Updated OpenCore to 1.0.1 nightly
• KEXTS
  • Updated VoodooInput.kext to latest nightly build so the trackpad works
  • Disabled AirportItlmw (incompatible with Sequoia)
  • Enabled Itlwm.kext (use Heliport App to connect to WiFi)
• NVRAM
  • Added -lilubetaall boot-arg → required for now to boot macOS 15

Important

• Reset NVRAM before booting!
