BOOM! SOLVED! - Well, sort of. I mean I have mt installed now, but it sure was not how I did it before. I downloaded some code from GitHub and figured out how to compile it in Xcode (first time ever using Xcode) and got it all working now.
But if anyone knows what I did last time I would really like to know.
I should probably write this down or something, right?

But now that I want to migrate this date to LTFS I can't remember exactly how I got the TAR tapes mounted and my notes are lacking. And I can't figure out how I figured this out before.. My notes consist of the following…

But obviously I was using mt to control the mounting of the tape and moving the tape from record to record. And I actually remember doing that part. So obviously I had a system that had mt installed. But how? I can't figure out where I got it from for the Mac. Or how I got it installed. I'm not even sure how I was ever that smart.
