@Sniki Never thought I'd get running Big Sur this fast! Thanks a ton! Everything works just fine, aside from the brightness control, like
@thedomis reported. Likewise, it starts working after closing and opening the lid.
For everyone running a DW1560, to have working WiFi in Big Sur you need to:
- Block (set to Enabled = False OR set MaxKernel to 19.9.9, which is Catalina) or remove AirPortBrcm4360_Injector.kext.
- Enable AirPortBrcmNIC_Injector.kext (set to Enabled = True and clear MinKernel & MaxKernel values).
