In the context of a Mac, the "driver" consists of several integrated components within the system's Kernel Extensions (kexts): Main Driver Extension : Primarily found within IO80211Family.kext , which contains the plugin AirPortBrcmNIC.kext AirPortBrcm4360.kext depending on the system version. : The "1.0" or similar version strings (e.g., 7.77.111.1

The is a historically significant but now obsolete wireless driver. It served Apple’s Macs reliably for several years, offering decent 802.11g and limited 802.11n performance. While it can still be used on PowerPC Macs or early Intel machines running Mac OS X 10.4–10.6, it is not recommended for modern macOS versions, security-sensitive environments, or high-throughput networks. In the context of a Mac, the "driver"
If you don’t want to use OCLP, you can try injecting the legacy kexts manually: While it can still be used on PowerPC
Warning: This method is unstable on macOS Ventura and newer due to security changes (Kernel Integrity Protection). OCLP is strongly preferred.
For Hackintosh users or those reviving legacy Broadcom cards, modifying the 1.0 driver is possible but fragile. Where possible, upgrade to a newer AirPort card (BCM4360 or above) and use the native AirPortBrcm4360 driver for superior performance and stability.
