I hope this is not a continuation of the Booting FreeBSD on iMac posting. I have an old iMac that barely survived flooding in my house during hurricane Harvey. It did sit and stew in a hot, wet environment for 9 days, so I do not know how long it will continue to run. What I would like to do is, if possible, is to turn it into a complete freeBSD command line machine, no GUI necessary (new iMac here), disk partitioning, no dual booting, etc. just for learning and messing around.
