AirPort BCM 4321 kext for MacOS Sierra on iMac 8,1 (early 2008)?

[TaoTeShaun]

Update... I installed the kexts as you posted, and it doesn't work at all, it recognizes the wifi but crashes immediately. The next I did was erase the IO80211Family.kext and all the variations of it, and install the OI80211Family.kext from Yosemite and it works OOTB!!! just install the KextFix.kext with Kext Utility and thats it. I don't know exactly how it works, but it does. It crashes suddenly but just restart and got the iMac working again...

I Hope this works for someone else with the same issue.

Where can I find KextFix.kext?

Hi bros, I have iMac 8,1 running BCM43xx (assumed that is 4321) on Mojave.
I tested the guidance from Tony's link post #22 not stable because the system keeps crash randomly after using the kext utility from Tony's link. Could you please help to guide how to utilize the suitable kext file? Thanks.
