Since the #BCM4360 in my 2013 #MacBookAir is not supported in #OpenBSD or #FreeBSD but is mounted in a slot and can therefore be removed, I wonder if anyone more knowledgeable than me can tell we whether it's possible to exchange it for an #Atheros based card for example. Since there are only two USB ports on the machine, I'd hate to block one for Wi-Fi. Also, the #Realtek one I got works but mysteriously maxes out at 1 MB/s throughput.
