Hi All,
I managed to get Mountain Lion installed on my M4400, but I can't get the WIFI to work. I have the DW1520 card, and have tried installing the kexts from the OP link into E/E and S/L/E and neither seems to work.
My system is an M4400: 2.53 Ghz QX9300 processor, 8GB RAM, FX770 512MB video card, Broadcom DW1520 WIFI card and 10.8.2 installed. Everything else seems to work fine, but I can't get the WIFI to work. I know the card works because it works fine in Win7.
thanks,
Kevin
