There are many threads on this subject. What we know:

a) BIAB 2019 for Windows is 64 bit and has been out a few months now.

b) A 64 bit version for Mac is supposed to be on its way.

c) No release date has been announced

d) No beta has been released

e) The current versions of BIAB 2018 work well in Apple's currently supported OS: Sierra, High Sierra and Mojave

Since (e) is true, BIAB 2019 for Mac will have to be compatible with OS 10.15 and the developer beta of that OS was released this week, (c) and (d) make a lot of sense to me.

I have my upgrade $$$ budgeted, too.
