So long as you don't mind running FreeBSD 12.0-CURRENT #1 r329009M and apply the patch in the following wireless mailing list post https://docs.freebsd.org/cgi/getmsg.cgi?fetch=0+0+current/freebsd-wireless I'm extremely happy to report that my MacMini no longer needs a cheap Chinese pocket router attached to the ethernet port but actually uses the inbuilt Broadcom BCM4321 wireless adapter on the 5G band
Thanks to Landon J Fuller for the miracle patch!
