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!
  • Disable AirportItlwm, enable itlwm and set SecureBootModel to Disabled prior to updating to macOS 14.4 or newer! You can restore the settings afterwards.
  • Don't update the following Kexts:
    • AppleALC
    • itlwm
    • IntelBluetoothFirmware
    • VooodooSMBus
