I'm at a point where I'm ready to upgrade (currently still have BB 2019 audiophile)....When is the 2023 Mac version expected to be available?

Past actions are no guarantee of future actions.

Having given a disclaimer, PG Music traditionally releases Band-in-a-Box for Mac in June or July.

PG Music normally does not publish release due dates in advance of a release.

As Jim said, June or July. I upgrade every year as a birthday present to myself

It has been as early as March and as late as September. We’ll know when we know.
