troorl Posted December 7, 2020 Share Posted December 7, 2020 Hi. I managed to install Big Sur, using Hervé's guide, though I had to remove the SSDT, otherwise it didn't load. I know my custom WiFi controller, DW1510 / BCM94322HM8L, is not supported anymore natively. So I tried two methods: injecting IO80211Family.kext (kernel panic) and AirPortAtheros40.kext & HS80211Family.kext (no effect at all). In both cases I just made a snapshot and cleanup in Propertree without additional editing. Frankly, I've no idea what I'm doing at this point, but a network connection would certainly help. I have the low-res model and the A20 BIOS. If there are other ways to make it work, please let me know. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 7, 2020 Administrators Share Posted December 7, 2020 Obviously, Atheros40 kext is for Atheros cards and would therefore be of no use at all for a Broadcom card! Try this. Link to comment Share on other sites More sharing options...
troorl Posted December 8, 2020 Author Share Posted December 8, 2020 Yay thank! It worked out perfectly! I was serious when I said that I had no clue what I was doing Link to comment Share on other sites More sharing options...
