Great Project thanks! works pretty well except wifi on my 13 inch 2019 mbp Maybe because it uses the BCM4377 and i can't find any information about linux support. brcmfmac doesn't even attempt to load.

output when i run: ioreg | grep RequestedFiles

"RequestedFiles" = ({"Firmware"="C-4377s-B3/formosa.trx","TxCap"="C-4377s-B3/formosa-X3.txcb","Regulatory"="C-4377s-B3/formosa-X3.clmb","NVRAM"="C-4377s-B3/P-formosa-X3_M-SPPR_V-u__m-3.1.txt"})

so i copied these files, renamed them according to the guide and put them into /lib/firmware/brcm. then i tried adding into brcmfmac source files (just replaced the chip_id and hw_id in wifi.patch). After compiling brcmfmac sees the chip and loads the firmware, but no interface is created. output of dmesg | grep brcmfmac:

Finally the support has arrived
