Hi @ma2thiasfiedler,

This was caused by an issue in 4.0.0.18002.6 where wireless.py skipped injecting IOSkywalkFamily on macOS 15/26.

We fixed this in the latest release. Please update to 4.0.0.18003.1 (or our build 4.0.0.18002.9):

1. Build and install OpenCore to your EFI drive.
2. Reboot.
3. Run Root Patching (Modern Wireless).
4. Reboot again.

Wi-Fi and audio will work normally.
