When I turned by old Thinkpad T440s into a hackintosh I bought a Wi-Fi dongle because the Intel AC7260 Wi-Fi + Bluetooth card is not supported by macOS, no Intel cards are. You can get Wi-Fi + Bluetooth card used by Apple as I did in my desktop, but sometimes you do not have much choice. If you use a hackintosh you have to choose your hardware carefully to make sure it is supported by macOS.
