Ok. Sorry can you suggest me one from the list of supported one? I want to buy the less-pain card possible. Why intel supported cards are not displayed? They are all compatible?

Ok I followed point 5, cleaned all duplicates of kexts. I copied IO80211Family.kext into L/E folder, repaired permissions and built cache but nothing. (I removed airportbmfixup) Now i tried to add the kext into S/L/E but nothing again

Hello, I was able to run Mac Os Catalina on my dell e6220. Everything is working right but not the wifi-card. I don't have intel card but a broadcom one. The card is BCM 43228. I've tried with Airportbrcmfixup kext and also with IO80211FamilyV2.kext but no way to make it work. Any ideas? (The kexts are in Volumes/EFI/EFI/CLOVER/kexts/Other and also in /System/Library/Extensions with Hackintool o Kext Utility installation based). Thank you for your help!!! The card it's a DW1530.

Hi, someone knows how to install Mac Os Big Sur on my dell latitude e6220 using opencore? Here I found the guide for High Sierra maximum and Big Sur only on the e6230 model. If someone has done it with success could you please upload your config.plist file?? Thank you all.
