I successfully installed macOS 10.12 "Sierra" onto my 2008 Mac Pro 3,1 (not officially supported, but works just fine with the Sierra Patcher). The only issue I have run into is that Sierra recognises but won't drive my USB WiFi dongle, which I use primarily to drive my Samsung Smart-TV. The Mac Pro serves an extra duty as the media file server to host movies and tv series. I am aware that there is an internal WiFi card available, though my Mac Pro has never had one installed. Are there any recommendations for adding WiFi to my Mac Pro, that will work with Sierra?
