For anyone running Hackintosh on Sonoma / Sequoia / Tahoe with Broadcom FullMAC WiFi:
I wrote a detailed guide to AppleBCMWLANCompanion (BCMC) based on the official docs + InsanelyMac thread + a Tahoe + BCM43602 success report.
It covers supported OS builds, firmware layout, device properties, AppleVTD/VT‑d, limitations (no AWDL/AirDrop) and when BCMC vs OCLP vs new hardware makes sense.
