macOS 14 Sonoma
As we all know, Apple's macOS 14 has finally targeted Broadcom wireless cards. The BCM94360 / BCM943602 cannot be driven on Sonoma. The current solution is to use OpenCore Legacy Patcher, which can perfectly drive Broadcom wireless cards. The only drawback is that you need to patch with OpenCore Legacy Patcher every time you upgrade the OS. Below is the operation tutorial.
OpenCore Legacy Patcher has preliminary support for macOS Sonoma. Original text: https://github.com/dortania/OpenCore-Legacy-Patcher/pull/1077

Extra: Broadcom Wireless Card Speed Issue
As early as macOS 13, I discovered that some Broadcom wireless cards, although plug-and-play, have low speeds (below 350Mbps) after connecting. At first, I thought it was a wireless router problem, but later I found out that the region code needs to be adjusted.
