I’m not sure that Windows versus Mac is relevant here, but I can’t check because I don’t have the Mac version. It wouldn’t surprise me a bit if the ever-changing Mac OS no longer supported it, assuming it ever did which I don’t know.

The code for supporting the Frontier Design Tranzport was still there in the Windows version the last time I checked only a couple of years ago. I still have a Tranzport and it actually did work at that time.

The request I’ve been making for a few decades is to support the Mackie Control Surface protocol. If BIAB had that, we could do a lot more than transport control. We could control track volumes with automated faders, and panning with knobs etc. The company did acknowledge this request about five years ago and said it might be possible to build on the code for the Tranzport. I am not aware of anything further. Unfortunately, development of hardware that supports the Mackie protocol appears to have stopped. I would therefore imagine the preferred solution now is to use a tablet (like an iPad). I do this in my DAW, Studio One. At one point it appeared BIAB was going in this direction.
